Procurement Notes
Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets the necessary automotive quality standards for your application. Check for any end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.
Selection Notes
Select this model when an automotive-qualified MCU with programmable analog resources is required. Ensure the design utilizes the available 24 I/O pins and fits within the 8 kB Flash constraint. Verify that the 24 MHz processing speed satisfies the real-time performance requirements of the target embedded system.
Part Context
This component belongs to the Infineon PSoC 1 family, specifically the CY8C21x45 series designed for automotive environments. It integrates a Harvard architecture CPU with reconfigurable analog and digital blocks, allowing designers to replace multiple discrete components with a single programmable chip.
Replacement Considerations
Consult official datasheets for cross-referencing with other CY8C21x45 variants. Verify pin compatibility and resource availability before substituting with similar models from the same product family.
