Product Introduction

Overview

The STM32L151VBH6D is an ultra-low-power microcontroller from STMicroelectronics, based on the ARM® Cortex®-M3 32-bit RISC core. It operates at a frequency of up to 32 MHz and delivers 33.3 DMIPS. This MCU is designed for low-power applications, featuring a comprehensive set of power-saving modes and a wide range of peripherals and interfaces.

The device includes high-speed embedded memories such as up to 128 Kbytes of Flash memory, up to 16 Kbytes of RAM, and up to 4 Kbytes of true EEPROM. It also features a memory protection unit (MPU), reset and supply management, and ultra-safe, low-power brownout reset (BOR) with 5 selectable thresholds.
