Procurement Notes

Verify the specific suffix LTXI confirms the 24 MHz speed grade and TQFP package variant. Confirm RoHS compliance status and check for any recent lifecycle notices or obsolescence warnings directly from Infineon's official documentation before procurement.

Selection Notes

Select this component when a mixed-signal microcontroller with high configurability is required. Ensure the design utilizes the available GPIO count and that the 24 MHz clock speed meets timing requirements. Verify power supply voltage ranges match the application's battery or rail specifications.

Part Context

This part belongs to the PSoC 1 family, designed for applications requiring flexible hardware acceleration. It combines a standard 8051-compatible core with Field-Programmable Analog Blocks (FPAB) and Digital Interconnects, allowing designers to create custom peripherals without external components.

Replacement Considerations

Check Infineon's official cross-reference tools for direct pin-to-pin replacements within the PSoC 1 series. Consider newer generations like PSoC 3 or 4 if enhanced performance or updated toolchains are needed, noting architectural differences.
