XR872AT

圖像采集編碼WiFi芯片;

XR872 delivers a highly integrated high performance Wi-Fi wireless System-on-Chip (SoC) solution designed for Artificial Intelligence and Internet of Things (AIOT) applications, such as smart audio, face detection and recognition, Machine-to-Machine (M2M), Smart Home, Cloud Connectivity and Smart Energy. \r\n\r\n\r\n\r\nThe XR872 application subsystem is powered by an ARM Cortex-M4F CPU that operates up to 384MHz. It supports an integrated 416KB SRAM and 160KB ROM, a QSPI interface to SIP up to 16MB Flash, a OPI interface to SIP 4MB PSRAM. Integrated I-cache enables Execute In Place (XIP) from flash and PSRAM, and integrated D-cache enables read and write from PSRAM. It also includes many peripherals, including UART, TWI, SPI, DMIC, AUDIO CODEC, PWM, CIR (T/R), CSI, SDIO and auxiliary ADC. \r\n\r\n\r\n\r\nThe Wi-Fi subsystem contains the 802.11b/g/n baseband, MAC and radio with integrated PA, LNA, Switch and harmonic filter, which is design to meet both the low power, high integration and high performance network application. A novel digital RF transmitter is design using XRADIOTECH’s MPDTM technology to deliver higher output power and maintain higher efficiency, and also to keep the chip not sensitive to antenna mismatch but always have good EVM at different VSWR. \r\n\r\n\r\n\r\nThe SoC is optimized for low-power operation by using several low-power state and fast wake-up times from hardware to software. Multiple power domains and clocks can be shut down individually. The application subsystem and Wi-Fi subsystem can be put into low-power states independently, supporting a variety of application use cases. Also an optional external DC-DC regulator can provide voltage from 1.5V to 2.5V for whole VDD_ANA power domain with on chip DC-DC control signal, without sacrificing standby power consumption even using high quiescent current DC-DC.
