Overview

The STM32L152CBT6A is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M3 core, operating at frequencies up to 32MHz. It features 128KB of Flash memory, 32KB of RAM, and 4KB of true EEPROM, integrated with a dedicated LCD driver for low-power display applications.

Why Choose This Part

The device excels in power-sensitive designs by offering seven low-power modes and a high-efficiency Cortex-M3 core. It includes 5V tolerant I/Os and integrated EEPROM, reducing bill-of-materials cost and complexity compared to external memory solutions.

Applications

Battery-Powered Medical Devices
Ideal for portable glucose meters and heart rate monitors due to its wide 1.65V to 3.6V supply range and low standby current.
Utility Metering
Utilizes the integrated LCD driver and RTC for water or gas meters requiring decade-long battery life.
Industrial Sensor Nodes
Leverages 12-bit ADC/DAC capabilities and various serial interfaces for remote monitoring in low-duty cycle environments.
