The STM8L101G3U6A: No last-time-buy risk or forced redesign for this order code.
16 MHz core — enough for sensor fusion and control loops
The 16 MHz clock rate on this 8-bit STM8 core is typical for the EnergyLite family. It handles sensor polling, UART/I²C/SPI communication, and simple control loops without breaking a sweat.
Memory budget: 8 KB Flash, 1.5 KB RAM, 2 KB EEPROM
8 KB of program Flash is tight but workable for a single-purpose controller — think a fan motor driver or a temperature monitor. The 2 KB EEPROM is a real advantage: calibration constants, fault logs, or configuration parameters survive power loss without external storage. 1.5 KB RAM limits buffering, so plan for small packet sizes on the UART.
Package: 28-UFQFPN, 4x4 mm
The 28-pin UFQFPN (4x4 mm) is a compact QFN-style package with an exposed pad.
