MICROCHIP WILCS02UE-I/100 Wi-Fi Module, U.FL Connector, Link Controller, 2.4 GHz, ADC, DAC, GPIO, PTA, SDIO, SPI, UART

WILCS02UE-I/100 is a Wi-Fi Link controller module with U.FL connector for external antenna. The WILCS02 is a fully RF and Wi-Fi Alliance®-certified wireless module based on the WILCS02IC. The device provides Secure Digital Input Output (SDIO) or Serial Peripheral Interface (SPI) to interface with the host controller. The WILCS02IC is a single chip 2.4GHz and IEEE 802.11b/g/n-compliant solution with integrated High Power Amplifier (HPA), Low-Noise Amplifier (LNA) and Radio Frequency (RF) switches for TX/RX control. It is a Link Controller IC with a hardware-based security accelerator.
