Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product catalog to ensure compatibility with required temperature ranges and supply voltages. Confirm that the 144-pin MQFP package matches your PCB footprint design. Check for any obsolescence notices or recommended alternative components in official Infineon documentation before finalizing procurement plans.

Selection Notes

Select this derivative when 32 KBytes of program memory is sufficient for the application code. Ensure the system design accommodates the 144-pin MQFP package constraints. Verify that the 40 MHz maximum frequency meets the timing requirements of the external peripherals and memory interfaces integrated into the design.
