W801 RISC-V WiFi/BLE combo from Winner Micro
W801 is a WiFi/BLE IoT SoC manufactured by Winner Micro, which is based in Beijing, China. It has rich on-chip peripherals. The key features are: 2.4GHz IEEE802.11b/g/n Bluetooth/BLE 4.2 dual mode Integrated 32bit C-Sky V2 core General Purpose IO: GPIO/ADC Rich communication interfaces: UART/SPI/I2C Special interface: I2S/7816/SDIO UI interface: LCD/Touch sensor Memory interface: PSRAM Security module: TEE with hardware encryption algorithms Built-in DSP Built-in FPU Code protection 2MB XIP flash memory with code encryption, signature, secure debug, secure OTA GCC support PS: C-Sky V1 was M-core from Motorola semiconductors, and C-Sky V2 was upgraded and revised. Assessment: XIP flash may have some restriction on execution speed and power consumptions. Some time critial code has to run in the RAM ADC precision is low and sampling rate is low. Lack of documentations and supports, although it is quite cheap. A complete SDK/toolchain is ready for OSHW community, but it is helpful for...
