Product details

STM8L151C8U6 — 8-bit MCU from the STM8L EnergyLite family

Memory and peripheral set for sensor and control tasks

The 4 KB RAM supports typical control loops and data buffering. A brown-out detect, power-on reset, and watchdog timer are integrated for reliable operation in noisy environments.

This surface-mount package is suited for compact PCB layouts where board space is constrained. The exposed pad aids heat dissipation when the MCU drives higher I/O loads or operates near the upper temperature limit. The package supports up to 41 general-purpose I/O lines.

For designs requiring a second source, the STM8L151C6U6 (64 KB Flash, 2 KB EEPROM, same package) is a pin-compatible alternative within the same family.

Frequently asked questions

What is the difference between the STM8L151C8U6 and the STM8L151C6U6?

Both are pin-compatible 8-bit MCUs in the same 48-UFQFN package and STM8L EnergyLite family. The STM8L151C8U6 offers 64 KB Flash and 2 KB EEPROM, while the STM8L151C6U6 has 32 KB Flash and 1 KB EEPROM. The RAM, peripheral set, and supply range are identical.
