Procurement Notes

Verify the specific suffix against official ordering guides to confirm package type and tape-and-reel specifications. Ensure the selected variant meets the required AEC-Q100 grade and temperature range for your target application environment. Cross-reference the datasheet revision history for any errata or functional updates relevant to this part number before finalizing procurement.

Selection Notes

Select this component when an automotive-qualified MCU with configurable analog and digital resources is required. The CY8C22345 offers high integration by combining an 8-bit CPU with flexible PSoC blocks, reducing bill-of-materials count. Consider the 48-pin SSOP package constraints and verify that the available GPIO count and peripheral configurations align with the system design requirements.

Part Context

This device belongs to the Cypress/Infineon PSoC 1 family, specifically the CY8C22x45 series designed for automotive applications. It utilizes the Harvard architecture M8C processor and features a unique programmable system-on-chip architecture. This allows designers to replace multiple fixed-function components with a single customizable chip, optimizing space and power consumption in automotive electronics.

Replacement Considerations

Consult the official Infineon product selection guide for direct cross-references. Verify compatibility regarding pinout, memory size, and automotive qualification grades when considering alternative microcontrollers.
