RF Transceiver ICS Procurement Notes

Verify the specific suffix 'MU-Y' against the official Microchip datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required operating voltage range of 1.62 V to 4.2 V. Confirm that the 128 KB program memory meets application requirements. Check for any recent product change notifications or errata sheets relevant to this specific variant before finalizing procurement.

RF Transceiver ICS Selection Notes

Select this component when a complete Wi-Fi solution with integrated power management is required. The ATWILC1000B-MU-Y is suitable for designs needing Bluetooth coexistence support. Consider the 2.4 GHz frequency band and 72.2 Mbps data rate limits. Evaluate the 63 mA receive current against battery life constraints. Compare against the broader ATWILC100x family if different memory sizes or interfaces are needed.

RF Transceiver ICS Part Context

This part belongs to the ATWILC100x series of RF SoCs from Microchip Technology. These devices are designed as single-chip radios/basebands/MAC link controllers. The series includes variants like the ATWILC1000A/B optimized for low-power mobile use and the WILC100/ATWILC1001A for IoT modules. All share common architectural features such as integrated PA, LNA, and switch capabilities.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other ATWILC1000 variants only if pinout and electrical specifications match exactly per official Microchip guidelines.
