RF Transceiver Modules And Modems Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the required host interface matches the design, as the component supports SPI, SDIO, I2C, and UART. Ensure the voltage supply range aligns with the 1.8V to 3.6V specification. Check for moisture sensitivity requirements during storage and handling. Validate that the operating temperature range meets the environmental conditions of the target application.

RF Transceiver Modules And Modems Selection Notes

Select this module for designs requiring a complete, certified Wi-Fi solution with minimal external components. It is suitable for space-constrained projects due to its integrated PCB antenna and small footprint. Consider the available interface options if the host processor lacks specific peripherals. The component is appropriate for applications needing reliable 2.4GHz connectivity with moderate data throughput requirements.

RF Transceiver Modules And Modems Part Context

This part belongs to the ATWILC1000 series, which are RF System-on-Chip (SoC) solutions combining radio, baseband, and MAC link controllers. The series is designed for Bluetooth coexistence and offers high performance in a low-power package. The MR110 variant specifically denotes a reference design module format intended for rapid prototyping and production deployment in IoT ecosystems.

RF Transceiver Modules And Modems Replacement Considerations

The ATWILC1000-MR110UB is a related module variant using a uFL connector instead of an integrated PCB antenna. Designers should verify antenna type compatibility and interface pinouts when substituting. Other family members like the ATWILC3000 offer different feature sets and require separate evaluation.
