The board is supplied by VBAT voltage in the range of 8 V to 18 V. The MCZ33905 provides 5 V to Hall
interface. The MCU and on-board logic are supplied by either 3.3 V or 5 V, depending on the assembled
SBC version. The board is populated with the 3.3 V SBC version by default.
The MCU generates one PWM signal for each phase. An additional on-board logic is used to split the
PWM signals to control power stage top and bottom switches separately. A PWM dead time is inserted by
additional hardware, if required.
The Fault logic triggers the DC bus undervoltage and DC bus overcurrent faults, and turns OFF the power
stage top and bottom switches. The circuitry behaviour depends on the selected configuration. For more
info, see Chapter 3.3, “Board Fault Management".

Interface Description
Chapter 2 Interface Description
The following chapters summarize the on-board connectors and header pin-outs, signal meanings and
MCU pins assignments.
2.1
Power Supply J1
The MC9S12G128 Controller Board can be supplied either by using the 2.1 mm DC power plug J1 or the
UNI-3 connector (J31, pin 19).
The controller board provides 5 V for a Hall interface and 3.3 V for on-board logic. Both voltages are
generated by the MC33905 SBC. Proper operation is monitored by LEDs D3 for the 5V line and D7 for
the 3.3V line (see Table 1-2).
The board is designed to operate in the voltage range from 8 V to 18 V. The board is protected against a
reverse battery.
2.2
UNI3 Interface J31
The Unified Interface Version 3 (UNI-3) defines the interface between the MC9S12G128 Controller Board
and the BLDC motor power stage.
The list of UNI-3 signal is as follows:
• Control signals:
— PWM phase A, B, C top and bottom switches control
— Brake signal control
— Power Factor Correction (PFC)
• Monitor signals
— DC-bus voltage
— DC-bus current
— Phase A, B, C current
— Zero-cross signals
— Back-EMF phase A, B, C
— Temperature monitoring
• Power Supply +12V
• Serial line - a bidirectional communication line between the Controller Board and Power Stage
The Table 2-1 defines the UNI-3 pin-out and pin assignment to the MCU.

Chapter 3 Design Consideration
This chapter provides an additional information on functional blocks of the MC9S12G128 controller
board.
3.1
MC9S12G128 Features
The MC9S12G-Family is an automotive 16-bit microcontroller product line focused on
low-cost, high-performance and low pin-count [2.]. This family is intended to bridge between high-end
8-bit microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS-Family.
The MC9S12G-Family is targeted at generic automotive applications requiring CAN or LIN/J2602
communication.
The MC9S12G128 MCU 100 LQFP features follows (see Figure 3-1):
• CPU12V1 core
• Memory
— 128 KB of Flash memory
— 4096 bytes of EEPROM
— 8192 bytes of RAM
• Clock modules:
— External oscillator
— Internal 1MHz RC oscillator
— PLL
• Connectivity:
— MSCAN, 1 module
— SCI, 3modules
— SPI, 3modules
• 16-bit timer, 8 channels
• 8-bit PWM, that can be configured as either 8 channel 8-bit PWM or 4 channel 16-bit PWM.
• 10-bit ADC, 16 channels
• MCU Supply voltage from 3.13 V to 5.5 V
• Execution speed 50MHz
The MC9S12G128 Controller Board is designed to use MCU PWM3, PWM5, PWM7 channels as power
stage phase A, phase B and phase C signals. The PWM1 channel is used primarily for proper timing of the
power stage DC-bus current and BLDC motor Back-EMF ADC conversion.

PWM /HS and LS Signal Split and Phase Dead Time Generation
The MC9S12G128 MCU PWM module generates one PWM signal per each phase. The power stage
requires separate PWM signals for each phase top and bottom switch.
The Figure 3-2 shows how the PWM signals are generated for motor phase A. The other motor phases are
controlled using the same logic circuitry.
The PWMA signal is split using the dual AND gate U3 into:
• PWMA_/HS signal:
— turn ON the power stage top switch, when reaches a low level
— turn OFF the power stage top switch, when reaches a high level
• PWMA_LS signal:
— turn ON the power stage bottom switch, when reaches a high level
— turn OFF the power stage bottom switch, when reaches a low level
In case of need to turn OFF the top and bottom switch simultaneously, the CTRLA signal is driven by
MCU low level and PWMA signal is driven high level.
The RC cell and diode are present on-board to insert a dead time approximately 2 micro seconds into the
phase PWM signal. Optionally this can be disabled using on-board jumpers, see Section 1.3, “Board
Jumper Configuration.”

Board Fault Management
The Faults can be processed either by MCU software or by an on-board hardware. The action depends on
jumper configuration, see Figure 3-3. and Table 1-1 J26, J27, J28, J29.
There are two sources of Fault condition (U6 comparator output high level):
•
•
/FLT_DET0 - fault is triggered whenever the signal level is below limit set by R57
FLT_DET1 - fault is triggered whenever the signal level is above limit set by R69
The /FLT_DET0 can be used for the DC bus undervoltage fault detection. The FLT_DET1 is designed for
the DC bus overcurrent detection.
The jumper J29 selects the source of overcurrent fault. Either the on-board comparator or the power stage
overcurrent fault signal, e.g. when using the MC33937A, determine the fault condition.
In fact, there are three options of fault processing, i.e. turning OFF power stage the top and bottom
switches:
1. MCU using the /IRQ pin - MCU software is responsible for the power stage switches turn OFF
2. Power Stage Enable pin - when the fault is captured by U8 the RS Flip-Flop, the EN signal goes
low. The power stage is responsible for turning OFF the switches.
3. on-board hardware - when the fault is captured by the U8 RS Flip-Flop, the U7 and U9 turn OFF
the power stage top and bottom switches.
For configuration, see Table 3-1.

Hall Sensor Interface
The Hall sensor interface is used for BLDC sensor based motor control applications. The Hall sensors are
used to determine the actual motor rotor sector.
The on-board interface provides the 5V power supply voltage to supply the sensors. The Hall interface
inputs are designed to support an open collector as well as push-pull Hall sensors outputs (see Figure 3-4).
A single pole RC low pass filter is present to reduce a signal noise.
For a detailed JP1 connector signal description, see Table 2-3.
Figure 3-4. Hall Sensor Interface
The Figure 3-5 shows the Hall sensor signal alignment to BLDC motor Back-EMF signal. The Hall
sensors detect the rotor flux, so their actual state is not influenced by stator current. The Hall effect outputs
in BLDC motors divide the electrical revolution into three equal sections of 120°. In this so-called 120°
configuration, the Hall states 111 and 000 never occur.
Based on the Hall sensor signal, the BLDC motor commutation table is developed. An example is shown
in Figure 3-6. The right-hand side of the table shows the Hall sensors signal, while the left side applied
phase voltage.

The board is designed to be supplied either by the UNI-3 interface or by using the on-board J1 connector,
power supply voltage from 8 V to 18 V. When using board as a standalone EVB, connect the power supply
to J1. In case of board operation with the power stage, it is recommended to supply board using UNI-3
interface.
The MC9S12G128 Controller Board (blue board) is designed for operation with the FSL MC33937A
based 3-Phase low voltage power stage (green board), see Figure 5-1. The complete 3-phase BLDC
Sensor/Sensorless Development Kit can be ordered at http://www.freescale.com/AutoMCDevKits.
