16 MHz STM8 core with EnergyLite architecture
The STMicroelectronics STM8L101F1U6ATR is an 8-bit microcontroller from the STM8L EnergyLite series, built around a 16 MHz STM8 core.
Memory and peripheral budget for control-loop tasks
With 2 KB Flash and 1.5 KB RAM, this MCU targets firmware footprints typical of sensor readout, simple motor commutation, or IR remote decoding. The 18 GPIOs, combined with I²C, SPI, and UART, give enough headroom to interface with a small display, a few sensors, and a serial link without needing external expanders.
