Overview

The STM32L151CCT6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M3 core, operating at frequencies up to 32MHz. It integrates 256KB of Flash memory, 32KB of RAM, and 8KB of true EEPROM into a compact 48-pin LQFP package. The device is specifically engineered for energy-sensitive applications, featuring a specialized internal multispeed low-power oscillator and a variety of power-saving modes.

Why Choose This Part

The STM32L1 series offers a unique combination of 256KB Flash and a dedicated 8KB data EEPROM, which reduces the need for external non-volatile memory. Its ultra-low-power architecture consumes as little as 0.29 uA in standby mode, while the Cortex-M3 core provides efficient 32-bit processing at 32MHz.

Applications

Battery-Powered Medical Devices
Utilizes the low-power sleep modes and integrated EEPROM for logging patient data and maintaining state in portable health monitors.
Industrial Sensor Nodes
Leverages the 12-bit ADC and multiple communication interfaces like I2C and SPI for remote monitoring systems with long battery life requirements.
Smart Metering
Ideal for gas and water meters that require high reliability, hardware ECC on Flash memory, and low standby currents to last years on a single cell.
Handheld USB Peripherals
Built-in USB 2.0 connectivity and capacitive touch sensing support make it suitable for low-power consumer interface devices.
