The STM32L151VCT6 from STMicroelectronics is a 32MHz ARM Cortex-M3 MCU with 256KB flash and 32KB RAM. It operates from 1.8V to 3.6V in a 100-LQFP package. Featuring Cap Sense, DMA, I2S, and low-power modes, it suits portable and touch-based applications.

  • Low power: Designed for battery-operated devices with multiple sleep modes.
  • Cap Sense: Integrated touch sensing reduces external components.
  • LQFP package: Easier to solder and inspect than BGA, ideal for prototyping.
  • Peripheral set: DMA, I2S, PWM, and WDT cover diverse needs.

Portable Instrumentation

Use low-power modes and 1.8V operation for handheld meters and loggers.

Touch-Enabled Panels

Implement capacitive touch interfaces for consumer appliances with Cap Sense.

Industrial Control

Run control loops with PWM and WDT in a 100-LQFP package for easy PCB routing.

Smart Meters
