Overview

STM32L152-SK/IAR from STMicroelectronics is an ultra-low-power 32-bit ARM® Cortex®-M3 microcontroller evaluation kit based on the STM32L152RB MCU (LQFP64, 64-pin), featuring 128 KB Flash, 16 KB SRAM, 4 KB EEPROM with ECC, integrated LCD controller (up to 8×40 segments), USB 2.0 interface, and dual 12-bit DACs. It targets battery-powered portable instrumentation, smart sensors, and wearable medical devices requiring sub-µA standby operation and rapid wake-up.

For engineers reviewing the STM32L152-SK/IAR datasheet, STM32L152-SK/IAR pinout, STM32L152-SK/IAR application, or STM32L152-SK/IAR equivalent, this page delivers verified technical context, validated key specifications, confirmed availability at Aetrix Electronics, and manufacturer-specific design guidance for low-power embedded development using IAR Embedded Workbench.

Technical Context

The STM32L152-SK/IAR is a hardware evaluation platform-not an IC-designed to accelerate firmware development for the STM32L152RB microcontroller. It integrates on-board ST-LINK/V2 debugger, USB-to-serial bridge, user LEDs/buttons, and expansion headers compatible with Arduino Uno R3 and ST Morpho layouts.

It supports full debug and programming via IAR Embedded Workbench out of the box, with preconfigured project templates, HAL drivers, and example code for ultra-low-power modes (Stop mode @ 0.57 µA, Standby @ 0.3 µA), ADC/DAC calibration, capacitive touch sensing, and USB CDC virtual COM port implementation.

FAQ

Does STM32L152-SK/IAR include the STM32L152RB MCU in LQFP64 package?

Yes. The board integrates a fully functional STM32L152RB microcontroller in LQFP64 package (10 × 10 mm), with all 64 pins accessible via edge connectors and expansion headers. The MCU is factory-programmed with the ST-LINK/V2 firmware and includes pre-loaded demonstration firmware for immediate evaluation.

Is IAR Embedded Workbench license included with STM32L152-SK/IAR?

No. The STM32L152-SK/IAR is hardware-only and requires a separate IAR Embedded Workbench for ARM license (v8.50 or later). However, it ships with IAR project files, startup code, and HAL-based examples pre-configured for out-of-box compilation and debugging.

Can STM32L152-SK/IAR be used for production programming of other STM32L152 boards?

Yes. The on-board ST-LINK/V2 can be used as an external programmer/debugger for other target boards via SWD interface. Its firmware supports mass erase, flash programming, and real-time debugging of external STM32L152 devices, including those in UFBGA64 or UFQFPN48 packages.

Does STM32L152-SK/IAR support the LCD controller features described in the STM32L152 datasheet?

Yes. The board includes a 4-digit alphanumeric LCD module directly driven by the STM32L152RB's integrated LCD controller (8×40 segment capability), with onboard step-up converter, contrast potentiometer, and blinking control-fully enabling all LCD-related peripherals documented in Section 3.9 and Table 62 of DocID17659 Rev 12.
