ISM43907-WM-L170 Serial-to-WiFi Evaluation Board


The ISM4370-WM-EVB is an embedded wireless evaluation board that is used to evaluate  2.4 & 5.0 GHz  Wi-Fi  module. The Wi-Fi module hardware consists of a Cypress 43907 SOC with ARM Cortex-R4 clocked at 320 MHz , 2 MB of SRAM and 640 KB ROM, all clocks, T/R switch and duplexer available for the applications processor, SPI or UART interface capability.

The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires the Cypress WICED SDK set to establish connectivity for your wireless product.  This product is targeted for 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:

  • ARM Cortex-R4 clocked at 160 MHz (in 1× mode) or up to 320 MHz (in 2× mode).
  • 2 MB of SRAM and 640 KB ROM available for the applications processor.


The ISM43907-EVB is an embedded wireless evaluation board that is used to evaluate the  802.11 b/g/n eS-Wifi module.  The evaluation board consist of a Wi-Fi module with host processor, supported by Cypress’s WICED SDK.

  • 802.11 b/g/n Compatible based on Broadcom MAC/Baseband/Radio device.
  • Fully contained TCP/IP stack thus minimizing host CPU requirements
  • Network features ICMP ( Ping), ARP, DHCP,TCP, UDP
  • Secure WiFi authentication WEP-128, WPA-PSK (TKIP), WPA2-PSK
