ti cc3220sf datasheet for security rf-wm-3220sfb1 ieee802.11b/g/n 13dbm 300m 2.4ghz wi-fi module interface
rf-wm-3220b1 series is a low power wi-fi soc module which is based on ti simplelinktmwi-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.
start your internet-of-things (iot) design with a wi-fi certified™ wireless module. the simplelink™ wi-fi® rf-wm-3220b1 series is a system-on-chip (soc) solution, that integrates two processors of an application processor arm® cortex®-m4 mcu and a network processor mcu with all wi-fi® and internet logical layers. rf-wm-3220b1 series modules are compatible with each other.
