Procurement Notes
Verify the specific ordering suffix against official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets. Check for continuity of part numbers as Cypress products are now part of the Infineon portfolio. Ensure development tools like PSoC Designer are compatible with the selected device variant.
Selection Notes
Select this component for designs requiring integrated capacitive sensing capabilities alongside standard microcontroller functions. Consider the 8-pin SOIC package constraints for pin availability. Evaluate the 12 MHz processing speed against application requirements. Verify that the 8 KB flash and 512 bytes SRAM meet memory needs.
Part Context
This device belongs to the CY8C20x34 series of PSoC Programmable System-on-Chips. These devices are designed to replace multiple traditional MCU-based system components with a single chip. The architecture includes configurable analog and digital blocks, a fast CPU, and programmable interconnect.
Replacement Considerations
Consult the official datasheet for alternative part numbers within the CY8C20x34 family. Verify pin compatibility and functional equivalence before substitution. Ensure any replacement maintains the required operating voltage and temperature specifications.
