TI CC3200 RF-WM-3200B3 Low Power Wi-Fi Module
RF-WM-3200B3 Wi-Fi module is based on TI CortexTM-M4 core Wi-Fi SoC CC3200. It is of 63 pin, 17.50 mm x 20.50 mm, and 1.27 mm pitch LGA package, fully pin-to-pin compatible to TI CC3200MOD. This Wi-Fi module features the best-in-class low power consumption performance, integrates powerful crypto engine for fast and secured WLAN connections with 256-bit encryption, and supports WPA2 personal and enterprise security. This module complies with 2.4 GHz 802.11 b/g/n standards. Its TCP/IP stack that runs on chip supports up to 8 simultaneous TCP, UDP, or ROW sockets, or 2 simultaneous TLS v1.2 or SSL 3.0 sockets. It can run in Station, AP or Wi-Fi DirectTM connection modes. This module has integrated an SPI Flash, a sleep clock crystal, and a fast clock crystal. It supports a wide supply voltage range from 2.3 V to 3.6 V. It has a pin-out of peripherals of 8-bit parallel, I2S, SD/MMC, UART, SPI, I2C, ADC, DMA and GPIOs interfaces. It also comes with a preprogrammed data communication protocol over its serial port and an AT commands set to simplify customers’ operations on Wi-Fi configuration.
