The STC8H1K08 is a microcontroller from the STC (Shanghai Sinowealth Technology) family of microcontrollers. These microcontrollers are commonly used in a variety of embedded applications due to their cost-effectiveness and robust feature set. Here are some key features and specifications for the STC8H1K08.

For Full project:


These microcontrollers boast an instruction speed that is about 12 times faster than traditional 8051 microcontrollers, with most instructions executing in just one clock cycle. They support clock frequencies up to 36MHz and operate within a voltage range of 1.9V to 5.5V. Standard peripherals include a 10-bit ADC, analog comparator, multiple timers, PWM, UART, SPI, and I2C. Additionally, they feature a built-in bootloader, enabling firmware uploads directly via UART without requiring an additional programming device.
