Product details

Overview

STM32L152C-DISCO from STMicroelectronics is a Discovery kit built around the STM32L152RCT6 ultra-low-power Arm® Cortex®-M3 microcontroller (256 KB Flash, 32 KB RAM, 8 KB EEPROM, LQFP64), featuring an on-board ST-LINK/V2 debugger, 24-segment LCD, four LEDs, two push-buttons, linear touch sensor, and touchkeys - designed for rapid prototyping of battery-powered IoT and portable sensing applications.

For engineers reviewing the STM32L152C-DISCO datasheet, STM32L152C-DISCO pinout, STM32L152C-DISCO application, or STM32L152C-DISCO equivalent, this board delivers validated hardware reference, SWD debug access, LCD/touch peripheral integration, and STM32Cube firmware support - enabling immediate evaluation of low-power modes, sensor interface, and human-machine interaction on the STM32L1 platform.

Technical Context

The kit implements a complete evaluation environment for the STM32L152RCT6 MCU, integrating its full I/O accessibility via LQFP64 extension header and supporting all ultra-low-power features including Stop/Standby modes with RTC and LCD controller retention. It uses ST-LINK/V2 firmware to provide dual-mode USB interface: Virtual COM port for serial communication and SWD for debugging and programming.

Power architecture supports flexible sourcing - from USB VBUS (5 V), external 3 V/5 V supplies, or internal LDO regulation - with dedicated IDD measurement points enabling accurate current profiling during sleep/wake transitions and peripheral activation.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	Arm Cortex-M3 @ 32 MHz - deterministic real-time execution with Thumb-2 instruction set for efficient code density and power control.
Memory	256 KB Flash + 32 KB RAM + 8 KB data EEPROM - sufficient for complex sensor fusion, secure boot, and persistent configuration storage in field-deployed devices.
LCD Driver	24-segment × 4-common integrated LCD controller - enables direct drive of segmented displays without external glass drivers, reducing BOM count for portable instrumentation.
Debug Interface	On-board ST-LINK/V2 with SWD and Virtual COM port - eliminates need for external debugger; supports flash programming, real-time variable monitoring, and UART-based host communication.
Touch Interface	Linear touch sensor + 4 capacitive touchkeys - provides intuitive user input with hardware-accelerated acquisition and noise-immune filtering via STM32's TSC peripheral.
Power Options	USB VBUS, external 3 V/5 V, or ST-LINK regulated supply - allows validation across battery, adapter, and USB-powered operating conditions with measurable current paths.

FAQ

Does STM32L152C-DISCO support programming and debugging without additional hardware?

Yes. The board integrates ST-LINK/V2 firmware on-chip, providing full SWD-based debugging and flash programming over USB. No external debugger is required - connection via standard USB Mini-B cable enables immediate use with STM32CubeIDE, IAR, or Keil toolchains.

Can the on-board LCD be used with custom glass or only the included display?

The 24-segment × 4-common LCD interface is exposed via dedicated pins on the MCU and matches standard segment/common drive configurations. While the board ships with a DIP28 24-segment LCD module, the driver supports external glass with identical multiplexing - verified in STM32L1 Reference Manual Section 29 (LCD Controller).

What low-power modes can be validated using this Discovery kit?

All STM32L152R-series low-power modes are accessible: Sleep, Stop with RTC/LCD active, Standby with wake-up from touchkey or RTC alarm, and Ultra-Low-Power Run mode. Current consumption down to 350 nA (Standby + RTC) is measurable via the onboard IDD test points and documented in AN4228.

Is the linear touch sensor compatible with STM32CubeMX-generated code?

Yes. The linear touch sensor is managed by the Touch Sensing Controller (TSC) peripheral, fully supported in STM32CubeMX v6.10+ and STM32CubeL1 firmware package. Configuration generates HAL_TSC APIs for position calculation, calibration, and noise rejection - no manual register-level coding required.
