TI CC3220SF Long range ultra-low power consumption RF-WM-3220B1 2.4GHz Wi-Fi Module
RF-WM-3220B1 series is a low power Wi-Fi SoC module which is based on TI SimpleLinkTM Wi-Fi? SoC CC3220S / CC3220R / CC3220SF, which has a built-in ARM CortexTM-M4 core processor with a user-dedicated 256 KB of RAM and an optional 1 MB of serial flash, a network processor MCU runs all Wi-Fi? and internet logical layers, and a variety of peripherals including parallel camera interface, I2S, SD/MMC, UART, SPI, I2C, ADC and GPIOs. The ROM-based subsystem of RF-WM-3220B1 includes an IEEE 802.11 b/g/n radio, baseband, and MAC with a powerful crypto engine. The module supports station, access point with support of four stations, and Wi-Fi Direct? modes. The device also supports WPA2 personal and enterprise security and WPS 2.0. The Wi-Fi Internet-on-a-chip includes embedded IPv4 and IPv6 TCP/IP protocols. The power-management subsystem includes integrated DC-DC converters supporting a wide range of supply voltages. This subsystem enables low-power consumption modes, such as the hibernate with RTC mode requiring less than 4.5 μA of current. The module design provides 3 options for antenna integration, including surface mounted chip antenna, an IPEX interface for connecting an external antenna, and a RF pad for soldering onto the base board and routing to an on-board antenna. RF-WM-3220B1 series is pin-2-pin compatible with RF-WM-3200B1.
