Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'LQIT' against official Cypress documentation to confirm package type and temperature range. Confirm RoHS compliance status as legacy components may have varying environmental declarations. Check for obsolescence notices from Infineon Technologies, the current owner of the Cypress portfolio, before finalizing procurement plans.

Application Specific Microcontrollers Selection Notes

Select this part when an integrated solution combining MCU logic with configurable analog/digital peripherals is required. Ensure the design utilizes the available 48 pins for necessary I/O and communication lines. Compare pin compatibility with other PSoC 3 variants if footprint constraints exist. Verify that the internal Flash and SRAM capacities meet the application's code and data storage needs.

Application Specific Microcontrollers Part Context

This component is part of the PSoC 3 family, which bridges the gap between traditional MCUs and FPGAs. Cypress Semiconductor was acquired by Infineon Technologies AG. The PSoC architecture allows designers to customize hardware peripherals via software tools, reducing the need for external discrete components in mixed-signal designs.

Application Specific Microcontrollers Replacement Considerations

Direct replacements should be sought within the PSoC 3 family or the subsequent PSoC 4/5LP families if pin-to-pin compatibility is not guaranteed. Consult Infineon's cross-reference guides for equivalent parts with updated supply chains. Verify that any substitute maintains the same package dimensions and electrical characteristics.
