Active 8-bit MCU for extended-temperature embedded control
The STM8L151G6U3TR is an 8-bit microcontroller from STMicroelectronics' STM8L EnergyLite series, built around a 16 MHz STM8 core.
Memory split and peripheral set that reduce external BOM
The 1 KB EEPROM block is separate from the program Flash — calibration coefficients, node IDs, and fault logs survive a firmware update without a dedicated external serial EEPROM.
Package and footprint for space-constrained designs
The 26 general-purpose I/O pins are enough for a keypad matrix, a few LED indicators, and a serial bus without a port expander.
STMicroelectronics lists the STM8L151G6U3TR as Active. The part is ROHS3 compliant.
