Description

The access line ultra-low-power STM32L031x4/6 family incorporates the high-performance Arm Cortex-M0+ 32-bit RISC core operating at a 32 MHz frequency, high-speed embedded memories (up to 32 Kbytes of Flash program memory, 1 Kbytes of data EEPROM and 8 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals. The STM32L031x4/6 devices provide high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation, and several low-power modes.
The ultra-low-power STM32L031x4/6 family includes devices in 6 different packages from 20 to 48 pins. The description below gives an overview of the complete range of peripherals proposed in this family.
