The STM32L151CBT6A is a low-power 32-bit MCU from STMicroelectronics, featuring an ARM Cortex-M3 core at 32MHz. It provides 128KB flash and 32KB SRAM, suitable for mid-range embedded applications. The device operates from 1.8V to 3.6V and includes Cap Sense for touch sensing, along with DMA, I2S, PWM, and WDT peripherals. Housed in a 48-LQFP package, it is designed for energy-efficient and space-constrained designs.

  • Integrated Cap Sense: Eliminates external touch controller, saving cost and board space.
  • Low power operation: Optimized for battery-powered devices with multiple low-power modes.
  • Balanced performance: 32MHz Cortex-M3 handles typical control tasks efficiently.
  • Rich peripheral set: I2S, DMA, PWM, and POR provide design flexibility.
  • Wide temperature range: -40°C to 85°C suits industrial environments.

Touch-Sensitive Control Panels

Integrated Cap Sense allows direct capacitive touch button implementation without external ICs, reducing BOM cost.

Smart Meters

Low power consumption and 32MHz processing are sufficient for metering calculations and communication protocols.

Alarm Systems

Multiple wakeup sources and WDT ensure reliable operation in security applications with long standby periods.

Portable Instrumentation

The 1.8V minimum supply enables operation from two alkaline cells, simplifying power design.

Building Automation

I2S interface supports audio processing for intercom or voice-command systems.

Medical Monitoring

DMA and analog peripherals facilitate continuous patient vitals monitoring with low power draw.
