Product Overview
The TXW816 is a low-power, high-performance, highly integrated 2.4GHz Wi-Fi + Small Wireless multi-mode IoT SOC chip, integrating IEEE 802.11 b/g/n baseband and RF (Radio Frequency) circuits, including Power Amplifier (PA), Low Noise Amplifier (LNA), RF balun, antenna switch, and Power Management Module, among others.
The TXW816 Wi-Fi baseband implements Orthogonal Frequency Division Multiplexing (OFDM) technology and is backward compatible with Direct Sequence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) technologies. It supports IEEE 802.11 b/g/n protocols. It supports 20MHz standard bandwidth and 5MHz/10MHz narrow bandwidth, providing a maximum physical layer rate of 72.2Mbit/s.
The TXW816 chip integrates a high-performance 32-bit microprocessor, with built-in MJPEG (supporting VGA/720P). It provides rich peripheral interfaces such as DVP, USB2.0 High Speed Device, SDMMC Host, SDIO2.0 Slave, RMII MAC, SPI Master & Device, UART, IIC, IIS, PDM, IR Send/Receive, PWM, GPIO, and ADC/DAC. It supports running programs on SPI Flash. It supports RTOS and third-party components, and comes with an open, easy-to-use development and debugging environment.
The TXW816 series includes multiple models, offering the mainstream QFN48 package type. Depending on the package type, the peripheral resource configuration within the device varies. Some packages support built-in PSRAM and Flash.
