XR809 is a highly integrated low-power WLAN Microcontroller System-on-Chip (SOC) solution designed for Internet of Things (IoT), Wearable equipment, Machine-to-Machine (M2M), Home automation, Cloud Connectivity and Smart Energy applications. The XR809 application subsystem is powered by an ARM Cortex-M4F CPU that operates up to 160MHz. It supports an integrated 384KB SRAM and 2MB Flash ROM. It also includes many peripherals, including UART, TWI, SPI, PWM, IrDA (T/R), SDIO and auxiliary ADC. The WLAN subsystem contains the 802.11b/g/n radio, baseband and MAC that designed to meet both the low power and high throughput network application. The SoC is designed for networked low-power embedded applications. It has an integrated network processor with a large set of TCP/IP with IPv4/IPv6 based services. These services can be accessed via a serial UART/SPI link connected to an external host CPU.
