Highly Integrated 2.4GHz Wi-Fi + BLE IoT SoC
TXW813 integrates a 2.4GHz Wi-Fi baseband, RF front end, PA, LNA, RF balun, antenna switch, and power management blocks for Wi-Fi IoT products, reducing external components and system design complexity.
IEEE 802.11 b/g/n Support, Up to 72.2Mbps
The chip supports 1T1R Wi-Fi and is compatible with IEEE 802.11 b/g/n, OFDM, DSSS, and CCK. It supports 20MHz standard bandwidth plus 5MHz/10MHz narrow bandwidth, with a PHY rate up to 72.2Mbps.
Flexible Wireless Modes with Secure Connectivity
Wi-Fi supports STA, AP, AP+STA relay, STA+STA, frame aggregation, RX STBC, and WPA/WPA2/WPA3 security. BLE supports fast provisioning and Wi-Fi/BLE PTA coexistence for smart home, gateway, and low-power connected devices.
High-Performance MCU with Low-Power Modes
TXW813 integrates a CK803 32-bit CPU running up to 240MHz and 272KB SRAM. It supports RTC, 32KHz crystal, 17 timers, watchdogs, temperature sensor, LVD detection, LP/ULP low-power modes, around 28uA ULP current, and multi-IO wake-up.
Complete Peripheral Interfaces for Product Expansion
The chip provides up to 20 GPIOs, 12-bit ADC/DAC, analog comparator, QSPI, USB2.0 High Speed Device, SDIO2.0 Device, SD Host, SPI, IIC, UART, IIS/PCM, PDM, IR transceiver, and multiple PWM channels for sensors, audio, storage, debugging, and production programming.
Security, Package, and Industrial Environment Support
Built-in AES-128/192/256, SHA256, CRC, SPI Flash firmware encryption, and TRNG improve device security. The QFN32 4×4 package supports -40°C to 85°C operation, and TXW813-320 integrates 2MB Flash for compact IoT terminals.
