Wi-Fi I/O for embedded systems

29 April 2009 Telecoms, Datacoms, Wireless, IoT

ZeroG Wireless has developed the ZG2100M ‘Wi-Fi I/O’, an easy-to-implement, low-power, low-cost Wi-Fi solution. Providing Wi-Fi connectivity for nearly any electronic device, the solution consists of ZeroG’s ZG2100 single-chip Wi-Fi, pre-certified modules, and the Easy-Fi software suite.

ZeroG technology has been developed specifically for integrating into the many microcontroller-based systems that have limited processing power, few memory resources and minimal or no operating systems, while requiring modest resources from the host system.

The ZG2100M is a module based on ZeroG’s single-chip ZG2100 Wi-Fi transceiver supporting data rates up to 2 Mbits per second. The ZG2100 is optimised for low duty cycle, low-power applications, featuring four different power modes, low leakage and a fast wake-up architecture. The device is also a true single-chip solution, with a complete on-chip MAC, power amplifier, baseband and hardware acceleration to support WEP, WPA and WPA2.

A key component of the Wi-Fi I/O is Easy-Fi software. The Easy-Fi suite includes a small and easily ported driver with a footprint that uses as little as a few hundred Bytes of RAM from a host microcontroller, and less than 10 KB of ROM. The driver includes a comprehensive suite of commands that allow it to run easily in small or no-OS systems.
