What the STM8S001 does
The STM8S001J3 is an 8-bit microcontroller featuring a 16 MHz core, 8-Kbyte Flash memory, and 128-byte EEPROM. It includes a 10-bit ADC, three timers, and communication interfaces supporting UART, SPI, and I2C. The device operates on a 2.95 V to 5.5 V supply with an internal 16 MHz RC oscillator. It offers up to 32 interrupts and supports low-power modes including active-halt and halt. Designed for embedded control applications, this MCU provides robust I/O design and on-chip debugging capabilities within a compact SO8N package.
