Procurement Notes
Verify the exact suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SSOP-20 configuration. Confirm RoHS compliance status through current manufacturer certificates before integration into production designs.
Selection Notes
Select this component when an 8-bit MCU with integrated CapSense capability is required. It is suitable for designs needing a balance of processing speed and low power consumption. Consider the 20-pin form factor for space-constrained layouts requiring limited I/O expansion.
Part Context
This part belongs to the PSoC 1 CY8C21xxx series, designed for cost-sensitive applications. It combines digital logic with programmable analog blocks on a single chip. The series is known for its flexibility in handling both digital control and analog signal conditioning tasks efficiently.
Replacement Considerations
Check for direct pin-compatible upgrades within the same PSoC 1 family. Verify if newer revisions offer improved performance or extended temperature ranges without altering the board design.
