Ultra-Low Power Wi-Fi Solutions from Renesas Electronics

Wi-Fi is the most widely deployed wireless LAN technology with the greatest amount of infrastructure in corporations as well as residential markets. Wi-Fi products from various vendors are interoperable: the Wi-Fi Alliance has certified hundreds of interoperable devices. Wi-Fi provides a platform to support IP (Internet Protocol) on Embedded systems. High levels of encryption and security via WPA2 allow these solutions to meet stringent enterprise IT requirements allowing for ready acceptance by IT departments worldwide.

Renesas partners with Qualcomm, Redpine, Silex, Longsys and Gainspan to provide easy-to-use Wi-Fi solutions. Longsys, Silex, Redpine and Gainspan provide Wi-Fi modules that provide key Wi-Fi Components (baseband, radio, power amplifier, antenna) integrated into a single module. These modules interface to any Renesas MCU through an SPI or UART interface and are directly integrated into the Renesas Synergy Platform via the Wi-Fi Framework.
