1.2 Description
RF-WM-3220B1 series is a low power Wi-Fi SoC module which is based on TI SimpleLink
TM
Wi-Fi
®
SoC CC3220S /
CC3220R / CC3220SF, which has a built-in ARM Cortex
TM
-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, I
2
S, SD/MMC, UART, SPI, I
2
C, 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.
