RZ/T1 Real-Time Motion Control Processor
Networking and Servo Drive Capabilities
Single-chip Solution for Precise
Motor and Servo Control
Engineers designing industrial systems from
advanced robotics, automated machines,
and motion systems require real-time
deterministic operation, high computational
performance, as well as network connectivity.
These enable overall system improvement
while reducing operational costs and saving
energy.
Key Features
■■ARM Cortex R4F CPU with
Tightly Coupled Memory for
real-time performance
■■Single/double precision
floating point improves
control loop arithmetic and
reduces memory footprint
The RZ/T1 processor addresses these needs
by combining the processing power and
real-time architecture to manage tighter
control loops, network connectivity to
support the latest industrial communication
protocols, and hardware integrated highspeed encoder interfaces, all to effectively
function as a servo solution on a single chip.
Built around the ARM® Cortex®-R4F core
running at up to 600 MHz with doubleprecision floating-point arithmetic, the
Renesas RZ/T1 processors readily
handle complex control algorithms.
Tightly coupled memory (TCM)
allows definitive real-time response
processing. The CPU gets highspeed access to code and data without
passing through cache memory.
■■Renesas R-IN Engine supports
multiple industrial protocols such
as EtherCAT, Profinet, Ethernet/IP,
Modbus TCP and more
■■Embedded encoder interface
supports both incremental and
absolute encoders
Motion in Real-Time - The integration of a high performance
processor, industrial networking support, and built-in encoder
interface reduces cost and time to market.
Industrial automation designs are
increasingly implementing network
connectivity via deterministic, openstandard networks such as EtherCAT®,
EtherNet/IP™ and PROFINET. Traditionally, this functionality has mandated
a separate ASIC with dedicated
communication functionality. RZ/T1

How to Achieve ‘Zero’ Stand-By Power Consumption in an
Offline AC/DC Converter
By: Giacomo Mercadante, Mirko Sciortino and Vittorio Giammello, STMicroelectronics
Regardless of the application or size, all industrial systems that
incorporate electronic controls or monitoring face a similar problem –
how do signals flow between sections, under harsh factory conditions?
One established solution is also the most simple: a two-wire slow
speed digital bus, called I2C.
Regulations which are in place today, or which are set to come into
force in the near future, are forcing manufacturers of electronic equipment to reduce stand-by power consumption in devices sold in almost
every developed region of the world.
Many kinds of appliances sit in an idle state most of the time. Today,
they normally waste energy simply because the user doesn't turn off the
mechanical switch, leaving the connection with the mains power line open.
Perhaps the heart of your system is a metal enclosure, rugged, and ready
for the factory floor? Or, the pieces of your system are spread out, and
interconnected with electrical cables? Perhaps you need to know about the
real world, with limit switches or temp sensors? Or, a human operator is
reading your data on displays, and pressing buttons manually.
In all of these cases the major components must be interconnected in a
reliable and simple way, to keep down costs and improve reliability. The I2C
bus, and the vast array of available direct connect I2C bus components, is a
sure solution to your interconnect needs.
Although the I2C bus has been around for a long time (back to the 1980s),
it remains a popular answer to today’s slow speed (up to 1MHz) digital data
interconnections, and uses only two wires (clock and data). There are LCD
and LED controllers, temp sensors, and GPIO (General Purpose Input/Output
to read many single switches or LEDs), plus when the bus must go further
than the originally intended single or small cluster of PCBs there are bus
buffers to boost the signal.
An important hurdle in system design, which is often built around a specific
core (CPU, MPU), is the fear of running out of IO ‘pins’ or channels. GPIO
is a handy solution, offering the designer many new pins by extending the
existing I2C bus with one or more GPIO devices. Better yet, the latest
offering of GPIOs operate directly from low voltage IO pins on today’s CPUs
and MPUs.
An often overlooked but important feature of industrial systems is time
keeping, important because as data moves around, the timestamp has to
remain valid and accurate. With an accurate and stable Real-Time Clock
(RTC) that consumes little power, uses minimal board space and has a local
battery backup, savvy designers will save the day in the event of utility
power loss.
Over the life of the I2C specification, many electronic components have
been introduced with much lower supply and signal voltage requirements;
in particular, more powerful CPUs and MCUs operate from one to two volts
instead of the five volts in vogue when I2C was invented. The NXP I2C catalog
includes many voltage level translators to bridge these disparate needs.
For those harsh industrial systems there is something new, a more robust
interconnection using the same protocol combined with the known reliable
addition of differential signaling – called dI2C. Take a look at PCA9614, the
easy way to upgrade I2C in an electrically noisy application.
We’ve refreshed some of the first components designed for I2C connections,
such as the ubiquitous LM75 temp sensor, which is replaced by the lower
cost and better accuracy PCT2075.
Now, however, there is a solution which solves this problem without having
to change the behavior of the user: the Zero Power mode in the VIPer0P,
an offline AC/DC converter from STMicroelectronics. Its clever on/off
management enables extremely low input power consumption even when
appliances are connected to the mains in an idle state.
In fact, as soon as the equipment completes its working cycle, it can be
automatically turned off and immediately switched on again only when
required. The control of the Zero Power mode is automatic with a microcontroller, or manual using a tactile low voltage button or remote-control
system. In fact, thanks to the VIPer0P’s Zero Power mode, mechanical
switches can be eliminated, saving bill of materials cost.
A simplified block diagram of the VIPer0P converter is shown in Figure 1.
It consists of an 800V MOSFET with on-resistance rated at 20Ω, and a fixed
frequency current mode PWM controller with overcurrent protection.
It operates at a jittered fixed frequency, reducing EMI filtering requirements.

Two different part numbers are available: the ‘L’ version is optimized for a
60kHz switching frequency, and the ‘H’ version for 120kHz. The user can
choose the frequency which best balances efficiency and transformer size.
The VIPer0P is also equipped with a light load management scheme which
ensures it achieves good efficiency even when supplying a load as small as
a few milliamps.
In the steady state, the IC supports either self-supply or an external supply.
Since it has a wide input voltage range of 5V to 30V, it can operate from an

Zero Power Mode for Stand-By Operation
A key feature of the VIPer0P IC is its Zero Power mode, an idle state in
which the device is totally shut down, the output voltage is zero, and the
residual power consumption from the mains is kept below 4mW at 230V
AC (see Table 1). All the IC’s functional blocks are turned off except those
needed to exit the mode. Microcontroller management of the operation of
the Zero Power mode is shown in Figure 2.
Figure 2: The operation of Zero Power mode may be managed by a microcontroller
An evaluation kit, the STEVAL-ISA174V1, shows that a power supply with
a built-in VIPer0P easily meets the demand of energy regulations such as
the European Union’s Code of Conduct for the efficiency of external power
supplies, and the IEC 62301 standard for zero power consumption in
stand-by mode. Moreover, the evaluation kit demonstrates pre-compliance
with IEC standards for EMC, EMI, surge current, burst-mode current, and
in-application ESD. The evaluation board implements a non-isolated flyback
topology, delivering about 7W across a dual output: 800mA on the -5V
output, 400mA on the +7V output. It uses the VIPer0P L version.
Values for the light-load and no-load power consumption of the equivalent
single output 12V/6.8W converter are shown in Table 1. Its active mode
efficiency, which is defined as the average of the efficiencies measured at
25%, 50%, 75% and 100% of maximum load, is 81.6% at a nominal 115V
AC input voltage, and 81.5% at 230V AC. This means that the single output
equivalent converter complies with the EU Code of Conduct and with US
Department of Energy standards.

In Figure 3, just as in the case of the MOSFET

that substantially affect IGBT performance. Here,
they are Ccg and Cge, respectively. Now, unlike the

by a resistor, here the conductive path is a PNP
structure that transitions from a high impedance
in the OFF state to a saturation voltage Vce(sat) in the

While good MOSFET and IGBT datasheets can
have well over 25 electrical parameters, here
we will limit our discussion to the most critical
parameters that must be considered for nearly every
application. Where possible, we will compare
and contrast the MOSFET and IGBT parameters
“in tandem”.

MOSFET, the Vds is the maximum voltage
between the drain (+) and the source (-) that
the device is rated to withstand in the OFF
state. Vce(max) is the analogous spec for the
IGBT. There is some temperature dependency
here, so care must be taken to account for the
thermal effects of transients. Units are in volts
measured across the drain source or collector
emitter terminals.
2.MOSFET RDS(ON) & IGBT Vce(sat) : For the MOSFET,
RDS(ON) is the Drain-to-Source ON State resistance. Units are in ohms measured across the
drain - source terminals. This parameter has
a POSITIVE temperature coefficient which allows MOSFETs to load share very easily when
connected in parallel. For the IGBT, Vce(sat)
is the saturation voltage when the device is
in the ON state. Units are in volts measured
across the collector emitter terminals. Vce(sat)
has a NEGATIVE temperature coefficient
which means it is hard to get
IGBTs to load share in parallel configurations.
This also makes them subject to thermal
runway. However, Vce(sat) does NOT increase
substantially for increasing current, which is
one of the IGBTs main performance advantages
over MOSFETS/IGBTs.
Figure 5: MOSFET/IGBT driver circuit
A MOSFET/IGBT drive circuit is often “asymmetric”
in that it presents very different impedances in
the ON mode vs. the OFF mode. That is, when
PWM is high, current is driven through R1 to turn
on the MOSFET/IGBT. To turn it OFF, PWM goes
low and current is pulled through R2. R1 is usually
substantially greater than R2 since the ON time is
often “throttled back” to control EMI while there
is a need to hold the gate low against the Miller
Capacitance effect.
4.I _ave and I_Pulse: These are the drain/collector average and pulse currents, respectively,
that the power device can sustain in the ON
state under a set of defined conditions including gate drive voltage, case temperature and
test current duty cycle. Units are in amps. This
parameter is limited by junction temperature
and, subsequently, the thermal impedance
and RDS(ON) /Vce(sat) of the device.
5.Maximum Power: This is a measure of the
maximum power the device can dissipate
1.800.FUTURE.1 • www.FutureElectronics.com
The most common cause of power MOSFET
and IGBT device failure is running the die at
an excessive temperature. To avoid this, it is
important to consider two critical design
concepts. These are Safe Operating Area (SOA)
and Transient Thermal Response.
Transient Thermal Response is the effect
that transients load currents have on the die
temperature in raising it from its “DC” value
towards, but hopefully not beyond, it’s safe
thermal limiting value. Here, the relevant
graph has a family of curves where each curve
corresponds to pulse duration. See Figure 7.

In Figure 6, the power device Safe Operating Area
for a range of conditions is shown. There are three
distinct regions. At the far right, the device is limited
by its ability to dissipate the average power +
the pulse power. In the middle region, the device
is strictly current limited. In the region on the left,
the device is not thermally limited, but rather
is functionally limited by voltages induced by
excessive currents, which in turn, would cause
operational problems.

As MOSFET and IGBT devices continue to
evolve, their relative advantages with respect to
one another will shift over time. However, due
to their respective strengths and weaknesses,
some generalities are likely to apply for some
time to come. In Figure 9, we see that there
are four regions where one device or the other
is fairly dominant. While the edges of these
regions are always somewhat in flux, their broad
outlines are not. For the region in the middle
that is bounded by the other for regions, specific
priorities of the application at hand are what
tips selection one way or the other.

IGBTs dominate here
To use a “Transient Thermal Response” graph,
follow these simple steps. First, calculate the
peak power through the power device during the
transient by multiplying the peak current and voltage
values. Then determine the pulse duration and duty
cycle. (tp, T & “§”, respectively). Next, locate the
t p of your test pulse on the X-Axis and follow a
vertical line from that point up to the appropriate
“§” curve on the chart. From that intersection
point, follow a horizontal line over to the vertical
“Y” axis to determine the “Ztr” for the particular
device under your given transient conditions. Now,
multiply the Peak Power value of the transient that
you calculated earlier by the “Ztr” value you just
found from the graph. The product of these two
terms is the value, in Kelvins or “°C” of the thermal
transient induced in the die by the load transient.
Finally, to get the resulting Peak Die Temperature,
this transient temperature value must be added to
the pre-transient “DC” value.

Safe Operating Area can be thought of
as the range or set of voltage and current
values across which a given device under given
conditions can be expected to operate without failure. Often, a family of curves will be
presented together with a range of load current
pulse conditions represented. See Figure 6.
Vds, Vde MAX limited
Again, at the simplest level, an IGBT can be
thought of as a MOSFET driving a PNP Bipolar
transistor. Here, the MOSFET gate acts to pull
current from the base of the PNP transistor
thereby turning it ON. Thus, the IGBT is something of a voltage dependent current source.
As in the case of the MOSFET model above,
the MOSFET inside the IGBT has similar input
capacitances that affect performance.

while its case is held to a given temperature.
Units are in watts. It is an indication of the
thermal impedance of the package and the
thermal limitations of the device material. It is
measured at a specified set of conditions such
as Vgs/Vge= 10V, Ids/Ice= 10A, case = 25°C.
6.Vth for MOSFETs: This is the Vgs at which the
channel resistance (Rds) has decreased from
fully OFF to within a specified percentage of
its fully ON value. Units are in volts measured
across the gate - source terminals. For IGBTs,
this is the Vge at which the device is fully
in saturation such that Vce is at a minimum.
Units are in volts measured across the collector
emitter terminals. Test conditions such as
Ids/Ice, Vds/Vce, Vgs/Vge are given in the
data sheet.
Key Application Points
This region is limited by RDS(ON)
or Vce(sat) respectively.
This is an operational, rather
than thermal, limit.
In Figure 1, the resistance (Rds) is a function
of the gate - source voltage. However, internal
parasitic capacitance between the terminals,
represented by Cgs & Cdg, must also be considered.
There is also an “intrinsic” body diode that is
effectively in parallel with the drain-source channel.
This diode has generally very poor performance
characteristics in that it is relatively slow to turn
off and has a high forward voltage, so for high
performance applications, a separate “fast recovery”
diode must be added in parallel with the FET.
Gate

Gate
3.Qg in both MOSFETs & IGBTs: This is a
measure of the total charge needed to raise
the gate to its full rated Vgs or “ON” voltage.
Units are in nCoulobs. In the past, values
were only given for Cgs/Cge and Cdg/Ccg
which, along with Vth (threshold voltage)
and the MOSFET drain/IGBT collector voltage,
collectively determine Qg. These two internal
capacitances are very influential in determining
the dynamic behavior of the MOSFET/IGBT.
For example, Cdg/Ccg, also known as the
Miller Capacitance, provides “negative
feedback” to the Gate, especially during fast
switching events. Thus, when trying to turn
the FET/IGBT ON by raising the gate voltage,
the voltage at the drain/collector will fall very
quickly. This, in turn, will pull charge away
from the Vgs/Vge via the Cds/Ccg and thus
tend to turn the device OFF again. Care must
be taken in the drive circuit to see that there is
sufficiently low impedance present to hold the
gate ON against this effect. Further, Cgs/Cge
has the effect of slowing down changes in Vgs
and thus changes in the channel resistance.
This, in turn, slows down the switching of the
MOSFET/IGBT and increases switching losses.
Maximum Device Current (Amps)
A Simplified MOSFET Model
At the simplest level, a MOSFET can be thought
of as a voltage dependent resistor. Referring
to Figure 1 below, the voltage between the
gate and the source determines the resistance
between the drain and the source. However, we
must consider a number of other elements in
order to arrive at a useful conceptual model of
any MOSFET component.

Power MOSFETs and IGBTs are actually fairly
complex devices with a number of parameters
that must be well understood to properly
apply them. In this article, we will review the
important operational parameters and key
application issues for each device. We will
then compare and contrast the performance
and applicability of MOSFETs vs. IGBTs and
discuss when to use one vs. the other.

Figure 10: MOSFET vs. Voltage
In Figure 10, we compare the voltage vs. current
transfer function for MOSFETs & IGBTs. Due to the
linear nature of the drain-source conductive channel
in the ON state, MOSFETs have a linear transfer
function. However, when an IGBT is in the ON state,
there is a three layer bipolar (PNP) structure in
saturation and thus its curve is non-linear and very
steep above a certain Vce(sat) voltage. Therefore,
there is a “crossover” point above which higher
device currents will result in lower losses in the
IGBT than in the MOSFET. The value of this
“crossover” point is changing with yearly process
and design improvements for each device.
