Product details

16 MHz 8-bit core with EnergyLite architecture

The ST STM8L151R8T6TR is a 16 MHz 8-bit MCU from the STM8 EnergyLite series, built around the STM8 core.

Memory mix and peripheral set

The 64 KB Flash (64K x 8) and 2 KB EEPROM (2K x 8) give firmware and calibration data separate non-volatile spaces — the EEPROM is rated for 100k write cycles typical, so you can store tuning parameters or counters without wearing the Flash. The 4 KB RAM (4K x 8) is modest; keep interrupt stacks and buffers lean.

Internal oscillator means no external crystal for the core clock, though an external clock can be used if tighter timing is needed.

Frequently asked questions

What is the closest pin-compatible alternative to STM8L151R8T6TR?

The STM8L151R8T6TR is a 64-pin LQFP variant of the STM8L151 family. Pin-compatible siblings exist with different Flash and RAM densities (e.g., 32 KB or 128 KB Flash) within the same package footprint, but the exact pinout and peripheral mapping should be verified against the STM8L151 reference manual.

What is the programming interface for STM8L151R8T6TR?

The STM8L151R8T6TR supports SWIM (Single Wire Interface Module) for in-circuit programming and debugging. It also boots from internal Flash with a strapping option.
