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...

I am back AGAIN Thanks to GFW, I have not been updated my blog for years.  Now I can access my blogspot account. Recently, the semiconductors market has changed a lot. After Huawei has been blacklisted, more and more chips are not allowed to sell to China anymore. Since the supply chain has been blocked for over two years, a lot of Chinese semiconductors companies stared their IPO and more products are released to the market as well as other areas, there chips include the following sectors: Memory: NOR/NAND flash, SSD, DRAM, SRAM, MRAM, EEPROM CPU: CPU for desktop, server, thin-server, gateway SoC: SoC for mobile, camera, TV and consumer video/audio, router and etc MCU: MIPS/ARM/RISC-V/8051 based MCU FPGA: entry level FPGA and CPLD NPU: standard alone APU or embedded NPU IP Logic: standard logic Discrete: power, IGBT and RF IP: EDA, IP vendors Market Trend I had worked for Philips/NXP semiconductors for 15 years. I know if the margin of a chip is lower than 30%, most of the se...
