Wi-Fi 802.11b/g/n Wireless Combo Module
Dual Band Wi-Fi… Bluetooth… NFC… Small Footprint
The ISM4334X-M4G-L44 is an embedded Serial to Wi-Fi module that operate in
the 2.4 & 5 GHz spectrum. The Wi-Fi modules hardware consists of a ARM M4
host processor with 1 MB flash, Broadcom BCM43340/1 Dual-Band (2.4 GHz / 5
GHz) 802.11 g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0, and NFC
including support for Bluetooth and Wi-Fi co-existence.
The module provides SPI and UART interfaces enabling easy connection to an
embedded design. The Wi-Fi module requires no operating system and has a
complete integrated TCP/IP Stack that only requires a simple AT command set
(IWIN) to establish connectivity for your wireless product minimizing develop-
ment time. The simple AT command, the low-cost, the small foot-print design
(14.70 x 34.22 mm), and the ease of design-in makes it ideal for a wide range of
embedded wireless appli
cations.
Main Features
Soft Access Point for up to 3 clients for
configuration and ad-hoc networks
Host interfaces: UART, SPI up to 25 MHz.
Network features ICMP ( Ping), ARP,
