Teh ATWILC3000-SHLD is a WILC3000 evaluation kit. This evaluation kit is a hardware platform to evaluate the ATWILC3000-MR110CA module. The ATWILC3000 is a single chip IEEE 802.11 b/g/n RF/Baseband/MAC link controller with support for Bluetooth 4.0. This module supports single stream 1x1 802.11n mode providing up to 72Mbps throughput. The ATWILC3000-SHLD features fully integrated power amplifier, LNA, switch and power management. Implemented in 65nm CMOS technology, the ATWILC3000-SHLD offers very low power consumption while simultaneously providing high performance and minimal bill of materials. It utilizes highly optimized 802.11-Bluetooth coexistence protocols and provides multiple peripheral interfaces including UART, SPI, I2C and SDIO. The only external clock sources needed for the ATWILC3000-SHLD is a high speed crystal or oscillator with a wide range of reference clock frequencies supported (14-40MHz) and a 32.768KHz clock for sleep operation.
