ATWILC3000A-MU-T

RF Transceiver ICS Overview

The ATWILC3000A-MU-T is a single-chip IEEE 802.11 b/g/n link controller with integrated Bluetooth 5.0, manufactured by Microchip Technology. It combines RF, baseband, and MAC functions in a 48-VFQFN package. The device operates at 2.4GHz with a maximum data rate of 72.2Mbps. Key electrical parameters include a transmitter output power of 19dBm and receiver sensitivity of -98dBm. Supply voltage is 3.6V, with receive current at 92mA and transmit current at 325mA. It supports I2C, SDIO, SPI, and UART interfaces, features 18 GPIOs, and operates within a temperature range of -40°C to 85°C.

RF Transceiver ICS Feature Summary

• Integrates IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.0 protocols on a single chip
• Combines RF transceiver, baseband processing, and medium access control functions
• Supports multiple serial communication interfaces including SPI, SDIO, I2C, and UART

RF Transceiver ICS Applications

• IoT sensor nodes requiring combined Wi-Fi and Bluetooth connectivity
• Smart home devices needing low-power wireless communication
• Industrial automation equipment with mixed protocol requirements

RF Transceiver ICS Procurement Notes

Verify the specific datasheet revision (e.g., DS70005427B) against your design requirements, as specifications may evolve. Confirm that the 48-VFQFN exposed pad thermal management meets your PCB layout capabilities. Ensure compatibility with the required operating temperature range of -40°C to 85°C for your application environment. Cross-check interface pin assignments for SPI, SDIO, or UART configurations before finalizing the schematic.

RF Transceiver ICS Selection Notes

Select this component when both Wi-Fi and Bluetooth 5.0 are required from a single silicon solution to reduce board space. Consider the 19dBm output power if long-range transmission is necessary. Evaluate the 325mA peak transmit current against your power supply capacity. Choose this part over separate chips if system complexity reduction and cost efficiency are primary design goals.

RF Transceiver ICS Part Context

This part belongs to the ATWILC3000 family of SmartConnect Wireless Network Controllers. It serves as an evolution of earlier WILC series devices, offering enhanced Bluetooth integration alongside standard Wi-Fi capabilities. The ATWILC3000A variant specifically supports Bluetooth 5.0, distinguishing it from older versions that may support only Bluetooth 4.0. It is designed for applications demanding compact, low-power wireless solutions.
