GainSpan has released wireless connectivity solutions said to make it quick and easy to add ultra-low-power Wi-Fi to embedded systems that use any Renesas 8/16/32-bit microcontrollers.

Now, Renesas Electronics users can add Wi-Fi connectivity using GainSpan’s GS1011M and GS1500M low-power Wi-Fi modules and develop their solutions with the Wi-Fi adapter boards, evaluation boards and drivers.

The Wi-Fi adapter boards come in two configurations: the WAB-GW-1011MIP Wi-Fi is an ultra-low-power 802.11b solution based on the GS1011MIP module; the GS1011 chip has a standby current as low as 1.2 µA and a wake-up latency from standby of less than 10 ms, suitable for battery-operated applications; the WAB-GW-1500M is a low-power 802.11b/g/n solution and includes the GS1500M module. The boards provide both UART and SPI interfaces, making it possible to connect to any Renesas microcontroller using simple AT commands. Additionally, the boards have built-in flash for reliable over-the-air firmware upgrade, factory restore configuration and data storage such as for web pages.

The GS1011MIP and GS1500M modules mounted on the boards provide easy system integration and minimal use of host resources. The modules are preloaded with serial to Wi-Fi firmware with complete Wi-Fi functionality including security, WPS and provisioning features running on the module as well as the networking stack, an embedded HTTP server with network configuration pages, and limited AP capability for ease of provisioning. The host microcontroller is hence offloaded from Wi-Fi and networking functionalities and could be dedicated to user applications.
