Overview
The STM32L152VBH6 is an ultra-low-power microcontroller from STMicroelectronics, part of the STM32L151x6/8/B and STM32L152x6/8/B series. It features the high-performance ARM® Cortex®-M3 32-bit RISC core operating at a frequency of up to 32 MHz, achieving 33.3 DMIPS. This MCU is designed for low-power applications, offering a comprehensive set of power-saving modes and a wide range of enhanced I/Os and peripherals connected to two APB buses.
The device includes high-speed embedded memories such as up to 128 Kbytes of Flash memory with ECC, up to 16 Kbytes of RAM, and up to 4 Kbytes of true EEPROM with ECC. It also features an 80-byte backup register and an integrated LCD controller (except for STM32L151x/6/8/B devices) that can drive up to 8 multiplexed LCDs.
The STM32L152VBH6 operates from a 1.8 to 3.6 V power supply, with an extended temperature range of -40°C to +85°C, and up to 105°C in low power dissipation state.
