Application Specific Microcontrollers Procurement Notes

This part number is listed as discontinued or end-of-life by the manufacturer. Availability is limited to surplus distributors such as Rochester Electronics LLC. Verification of lot date codes and storage history is recommended due to the component's obsolete status. Buyers should confirm functional integrity through testing before integration into production designs.

Application Specific Microcontrollers Selection Notes

Engineers selecting this component should note its specific pinout and electrical characteristics defined in the official datasheet. As an older generation Cypress MCU, it may require migration planning if long-term supply stability is critical. Alternative modern equivalents from Infineon or other vendors should be evaluated for future-proofing, considering interface compatibility and performance requirements.

Application Specific Microcontrollers Part Context

The CY8CTMA300E series represents Cypress's TrueTouch technology combined with an 8-bit MCU. These devices were designed to simplify human-machine interface designs by integrating capacitive touch sensing directly with the processing unit. The manufacturer was acquired by Infineon Technologies, which continues to support legacy documentation for existing customers.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements are not publicly confirmed for this specific suffix. Engineers should consult Infineon's current portfolio for updated TrueTouch MCUs. Cross-referencing with CY8CTMA100 or CY8CTMA200 series devices may provide functional similarities, though pinouts and software architectures differ.
