The ISM43362-M3G-L44-E/U is an embedded 2.4 GHz  Wi-Fi  module. The Wi-Fi module hardware consists of a Cypress BCM43362, an integrated antenna or optional external antenna, and a STM32F205 host processor that has a standard SPI or UART interface capability.

The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires a simple AT command set to establish connectivity for your wireless product. The module has a very small 14.5mm x 30mm surface mount footprint and has full FCC and CE module certification. This product is targeted for low cost embedded wireless applications and enables a quick, easy and cost effective method adding WiFi connectivity to your platforms. A summary of the key module features:

• 802.11 b/g/n Compatible based on Broadcom MAC/Baseband/Radio device.
• Fully contained TCP/IP stack thus minimizing host CPU requirements
• Configurable though AT commands.
• Host interface:  UART, SPI up to 25 MHz
• Network features ICMP ( Ping), ARP, DHCP,TCP, UDP
• Low power operation (3.3V supply) with built-in low power modes.
• Secure WiFi authentication WEP-128, WPA-PSK (TKIP), WPA2-PSK
