Santa Clara, CA-based Redpine Signals has introduced its Pine1-LP Wireless LAN (WLAN) Platform, claiming that it’s the world’s lowest power licensable 802.11b/g platform.
In operation, it draws less than 170mA [377mW] for the complete SDIO/SPI based WLAN reference design during a 54Mbps FTP download. VoIP calls draw only 12.5mA [35.6mW].
The company says that the platform can be built into low power, cost sensitive applications such as single and dual-mode mobile handsets, PDAs, digital cameras, MP3 players, gaming and printing platforms.
The Pine1-LP IEEE 802.11b/g reference design includes a baseband (BBP), media access controller (MAC), Analog Front End (AFE), an 802.11b/g RF transceiver and Power Amplifiers (PA), as well as SDIO and SPI host interfaces.
The SDIO interface is specifically designed to support full 54Mbps 802.11g data rates.
The Pine1-LP MAC, which supports the new 802.11i (security) and 802.11e (QoS) standards, is based on a unique programmable packet engine which off-loads all WLAN packet processing and TCP checksum calculations from the host resulting in lower power and increased system performance.
The platform has support for Bluetooth co-existence in the 2.4GHz band with popular Bluetooth chips.In addition, it includes an extensive suite of firmware and driver support for Linux, Windows CE 5.0 and other popular operating systems.
