The STMicroelectronics STM8L151C8T7 is an 8-bit MCU from the STM8 EnergyLite family, built around the STM8 core running at 16 MHz. With 41 I/O lines and a peripheral set including DMA, PWM, a watchdog timer, and brown-out detection, it fits as a central controller in sensor nodes, motor control boards, or handheld instruments.
Memory and analog integration
The 64 KB Flash and 4 KB RAM support a Modbus slave stack or a PID loop. The 2 KB EEPROM stores calibration constants or fault logs without external serial memory.
