Microchip Technology, Inc. RF and Wireless - RF Transceiver ICs ATWILC1000B-UU-Y

The ATWILC1000B-UU-Y is a compact IEEE 802.11 b/g/n RF transceiver IC designed for low-power mobile applications. It supports a single spatial stream in the 2.4 GHz ISM band, achieving a maximum PHY rate of 72 Mbps. The device integrates a Power Amplifier (PA), Low Noise Amplifier (LNA), and a T/R switch, contributing to its efficient performance and reduced bill of materials. This IC features multiple host interfaces, including Serial Peripheral Interface (SPI) and Secure Digital Input Output (SDIO), and operates with an external 26 MHz crystal. It is available in a Wafer Level Chip Scale Package (WLCSP) format, measuring 3.24 x 3.24 mm. The operating temperature range is from -40¬8C to +85¬8C, with a supply voltage of 1.62V to 3.6V for I/O and 3.0V to 4.2V for the power supply. Power management capabilities include a deep power-down mode with typical consumption of less than 1 OºA and a doze mode at 380 OºA, allowing for efficient energy use during operation. The ATWILC1000B-UU-Y supports various security protocols, including WEP, WPA, and WPA2, making it suitable for secure wireless communication applications.
