CYW43903 WICED™ IEEE 802.11 a/b/g/n SoC with an Embedded Applications Processor


The Cypress CYW43903 embedded wireless system-on-a-chip (SoC) is uniquely suited for Internet-of-Things applications. It supports all rates specified in the IEEE 802.11 b/g/n specifications.The device includes an Arm Cortex-based applications processor, a single stream IEEE 802.11n MAC/baseband/radio, a power amplifier (PA), and a receive low-noise amplifier (LNA). It also supports optiomal antenna diversity for improved RF performance in difficult environments.

The CYW43903 is an optimized SoC targeting embedded Internet-of-Things applications in the industrial and medical sensor, home appliance markets. Using advanced design techniques and process technology to reduce active and idle power, the device is designed for embedded applications that require minimal power consumption and a compact size.
