Description

The STM8L050J3M3 is an ultra-low-power 8-bit microcontroller from STMicroelectronics, based on the STM8 core. It operates at up to 16 MHz and features 8 KB Flash, 1 KB RAM, and 128 B EEPROM. Designed for energy-efficient applications, it supports multiple low-power modes (Halt, Active-Halt, Wait) with current consumption as low as 350 nA in standby.
Key peripherals include:
- 10-bit ADC
- Timers (16-bit & 8-bit)
- SPI, I²C, UART interfaces
- 12 GPIOs
It comes in a 20-pin SOIC package and is ideal for battery-powered devices like sensors, wearables, and IoT nodes. The STM8L series emphasizes cost-effectiveness while maintaining robust performance in power-sensitive designs.
For development, ST provides STVD/STM8CubeMX and supports programming via SWIM (Single-Wire Interface Module).
