Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature range. Ensure compatibility with required programming interfaces and voltage levels before procurement. Check for moisture sensitivity level requirements during storage and handling.

Application Specific Microcontrollers Selection Notes

Select this model when 16 kB of program memory and 2 kB of RAM are sufficient for the application logic. The 34 I/O count and integrated CapSense capabilities make it suitable for devices requiring direct touch interaction without external sensors. Confirm that the SSOP-48 package fits the PCB layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the Infineon PSoC 20xx6A family, which combines programmable analog and digital blocks with an 8-bit CPU. The CY8C20546 variant specifically offers higher memory capacity compared to lower-end models like the CY8C204xx series, while maintaining low power consumption characteristics typical of the PSoC 2 architecture.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the CY8C20xx6A series with equivalent or greater memory sizes, such as the CY8C20546A if available. Verify electrical specifications and firmware compatibility before substitution.
