Cypress MicroSystems Strategy

4 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.

The M8C Core in PSoC is used in the USB product



Proven Technology – 185+ million M8 microcontrollers sold

Microcontroller 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)

PSoC™ System on Chip Benefits

How do I know where to place the User Modules?

How does PSoC Designer help me?

How to Place User Modules

54 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



55

Place User Modules

Place the two selected UM’s in the default positions.

PWM16_1 – Digital Blocks DBA00/DBA01 PWM16_2 – Digital Blocks DBA02/DBA03 Recommend to put the PWM’s in the Basic Digital Blocks to Save the Digital Com Blocks

Configure Global Resources

56 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)

57

Configure Global Resources

Ref Mux: Set to (V cc /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%

Configure User Modules

58 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.

- Set Clock to 24V2 (94kHz) - Set Enable High to keep the PWM always running - Set Period to 65535 (1.4Hz) - Set PulseWidth to 13107 - Compare Type Less Then Or Equal Interrupt Type Terminal Count - Set Output to Global_OUT_2

PWM_8



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.

96

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
