Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check revision markings against datasheet specifications to ensure compatibility with existing designs. Validate electrical characteristics against recommended operating conditions before integration into final assemblies.

Microcontrollers Selection Notes

Select this model when 36 KB of non-volatile storage and 1 KB of RAM are required for complex control algorithms. Choose the QFN-32 package for compact surface-mount designs. Ensure design accommodates the specific I/O circuit types, particularly high-current outputs on Port 6. Verify that the external clock source meets the 32.5 MHz maximum requirement if utilizing the highest machine clock frequency.

Microcontrollers Part Context

This component belongs to the CY95630H series of general-purpose single-chip microcontrollers. Originally developed by Cypress Semiconductor, now part of Infineon Technologies, the series shares the F2MC-8FX core architecture.
