1 Device Overview
1.1 Description
RF-WM-3200B1 is a low power Wi-Fi SoC module which is based on TI SimpleLink Wi-Fi SoC CC3200, which has a
built-in ARM Cortex
TM
-M4 core processor, and variety of peripherals including parallel camera interface, I
2
S, SD/MMC,
UART, SPI, I
2
C, ADC and GPIOs. The subsystem of RF-WM-3200B1 includes an IEEE 802.11 b/g/n radio, baseband,
and MAC with a powerful crypto engine for fast, secure Internet connections with 256-bit encryption. The module
supports station, access point, and Wi-F
i Direct™ modes. The device also supports WPA2 personal and enterprise
security and WPS 2.0. The Wi-Fi Internet-on-a-chip includes embedded TCP and UDP 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 7 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-3200B1 is pin-2-pin compatible with RF-WM-3220B1 series.
