Product Overview
TXW812 is a low-power, high-performance and highly integrated 2.4GHz Wi-Fi plus low-power wireless multimode IoT SoC. It integrates the IEEE 802.11 b/g/n baseband and RF circuits, including the PA power amplifier, LNA low-noise amplifier, RF balun, antenna switch and power management modules, making it suitable for compact connected devices with strict power and cost targets.
The TXW812 Wi-Fi baseband implements OFDM and remains backward compatible with DSSS and CCK, supporting the IEEE 802.11 b/g/n protocol family. It supports 20MHz standard bandwidth as well as 5MHz and 10MHz narrow-band configurations, with a maximum PHY rate of 72.2Mbit/s for flexible tradeoffs among throughput, coverage and power consumption.
The chip integrates a high-performance 32-bit microprocessor and provides USB2.0 High Speed Host/Device, SDMMC Host, RMII MAC, SPI Master & Device, UART, IIC, IIS, PDM, IR Send/Receive, PWM, GPIO, ADC/DAC and other peripheral interfaces. It also supports SDIO2.0 Slave up to 50MHz, runs programs from SPI Flash, and includes RTOS support, third-party components and an open development and debugging environment for fast product delivery.
