RF Transceiver ICS Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted to limited stock or surplus channels only. Verify part authenticity and storage history carefully due to end-of-life status. No new production units are available directly from Infineon. Ensure compatibility with existing designs before procurement.

RF Transceiver ICS Selection Notes

Select this part for legacy designs requiring integrated RF and MCU capabilities in sub-1GHz bands. Consider the obsolete status when planning long-term production runs. Evaluate alternative components if future supply stability is critical. The specific package and interface requirements must match the target PCB layout constraints.

RF Transceiver ICS Part Context

The PMA7107 belongs to the SmartLEWIS family of radio microcontrollers from Infineon Technologies. This series targets cost-effective wireless solutions for simple data transmission tasks. The XUMA1 suffix indicates the specific tape and reel packaging configuration used for automated surface-mount assembly processes.

RF Transceiver ICS Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should evaluate newer generations of RF MCUs from the same manufacturer or competitors offering similar ISM band support and memory configurations.
