Cypress MicroSystems Strategy
Provide a Single Chip Programmable Solution for
small electronic products
Leveraging Cypress Semiconductors World leader
position in USB – 80% world Market share in the
respective market.

Current Embedded Marketplace:
• Each part covers small
functionality
• Families tend to cluster;
second sourcing leads to
overlaps
• Customers believe they
need custom micros
Cypress Strategy:
• Provide part numbers that
each cover MORE
functionality (i.e., cover
hundreds of competitive
devices)

53
How to Place User Modules
Try-out the modules individually first
 See how restrictive they are, then return to place
PSoC Designer will only allow the modules to be placed where
the chip can support them
PSoC Designer will not prevent a placement that may create a
conflict for resources
 Example: If you have an ADC and temperature sensor, they both
use the comparator bus. There is only one comparator bus per
column, therefore these two UMs must reside in separate
columns in order to be used simultaneously.
Read the UM Data Sheets for details
Use the Cypress MicroSystems Online Resources
 www.cypressmicro.com/support
54
Place User Modules
Place the two selected UM’s in the default positions.

Configure Global Resources
CPU_Clock: Set to 12MHz
32K_Select: Set to Internal
 Not using an external crystal
PLL_MODE: Set to Disable
 PLL can only be enabled when 32K_Select is External
(crystal)
Sleep_Timer: Set to the default value of 512_Hz.
24V1= 24MHz/ N: Set to 16
 This divides 24MHz by 16 = 1.5MHz
24V2=24V1/N: Set to 16
 This divides the 24V1 by 16 (1.5MHz/16=94kHz)
Analog Power: Set to SC On/Ref Low
 This is required to power up any of the analog blocks,
depending on the number of analog functions. A Ref
Med or Ref High may be required (and will increase
power consumption)
56
Configure Global Resources
Ref Mux: Set to (Vcc/2) ±Bandgap (the default)
Op-Amp Bias: Set to Low (the default)
 This is not recommended as anything but low
A_Buff_Power: Set to Low (default)
 This selects the power level of the analog output buffer
 There is a tradeoff between drive output
power and power consumption.
Low is adequate for most projects
SwitchModePump: Set to Off
VoltMonRange:
Set to 5.0V
VoltMonThreshold: Set to 80%
57
Configure User Modules
PWM_1: We want to generate a 1/5 duty cycle
User module parameters can be configured in two ways:
through the GUI or through the User Module Parameters
window. In this class we will use the User Module Parameters
window in the left bottom corner.

Electronic Ballast
For Flourescent Lamps Using PSoC
PSOC is ideal for
electronic ballasts:
control the lamp drive circuit
can also add connectivity.
Benefits:
Reduced circuit complexity/
lower build cost.
Digital dimming, networking.
Better “manufacturability” as
PSOC ballasts are the first
TRUE digital ballasts.

 Drives motor
UART
 Used to upload speed value to PC and download mode
to the PSoC
Baud rate clock
 57.6 kb/s
Communication interval timer
 2 Hz interrupt. Loads speed value into UART, updates
PWM.
PGA
 Connects thermistor network to ADC.
Delta-Sigma ADC
 Converts thermistor input.
95
PSoC firmware
LUT A
 Contains gain so that small temperature change results
in large change in fan speed.
LUT B
 Manual mode, increase in PWM duty cycle proportional
to movement of slide control in Lab View.
UART Interrupt Service Routine (ISR)
 Eliminates polling that may waste throughput.
Communication timer ISR
 2 Hz, updates PWM compare register, sends PWM duty
cycle to Lab View.
Main
 Initialize user modules, handles commands from Lab
View
Design will run without PC communication link
