Product details

The STM32L051C6T6 is an STMicroelectronics ultra-low-power 32-bit MCU built around the ARM Cortex-M0+ core running at 32 MHz. The 1.65 V minimum supply voltage lets it run directly from two alkaline cells or a single Li-ion through most of its discharge curve, saving a boost converter. Typical applications include battery-powered sensors, IoT edge nodes, portable medical devices, and industrial control panels where every microamp counts. The 48-LQFP package with 37 I/O gives enough GPIO for a keypad, a small display, and a few serial peripherals without needing a port expander.

Peripherals and connectivity

The 10-channel 12-bit ADC handles analog inputs like thermistors or potentiometers without an external converter.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L051C6T6?

The STM32L051C8T6 is pin-compatible and offers 64 KB Flash instead of 32 KB, in the same 48-LQFP package with the same supply range and peripherals. It is a drop-in alternative if the firmware requires more code space.
