STMicroelectronics STM32L562E-DK

Overview

STM32L562E-DK from STMicroelectronics is a Discovery kit built around the STM32L562QEI6Q Arm® Cortex®-M33 MCU with TrustZone® security, 512 KB flash, 256 KB SRAM, and BGA132 packaging. It integrates a 1.54" 240×240 TFT LCD, Bluetooth® 4.1, Octo-SPI flash, SAI audio codec, iNEMO IMU, and on-board energy meter (300 nA–150 mA) for ultra-low-power wearable and sensor-edge prototyping.

For engineers reviewing the STM32L562E-DK datasheet, STM32L562E-DK pinout, STM32L562E-DK application, or STM32L562E-DK equivalent, this kit delivers out-of-the-box debug via ST-LINK-V3E (mass storage, VCP, SWD), parallel LCD interface, DPM power measurement, and multi-standard expansion (STMod+, Pmod™, Arduino Uno V3, Grove, mikroBUS™).

Technical Context

The STM32L562E-DK implements Armv8-M security extensions via TrustZone®, enabling hardware-isolated secure/non-secure firmware execution and secure boot verification. Its target MCU supports dual-bank flash for seamless firmware updates and includes AES-256, PKA, and RNG accelerators.

Power architecture features three independent supply domains (VDD, VDDA, VBAT), dynamic voltage scaling, and ultra-low-power modes down to 300 nA in standby with RTC and 16-byte SRAM retention - validated by the integrated energy meter with dedicated USB interface.

FAQ

Does the STM32L562E-DK support secure firmware update over-the-air?

Yes. The onboard STM32L562QEI6Q MCU supports dual-bank flash and secure boot with public-key verification. The STM32CubeL5 software package includes examples for authenticated, encrypted OTA updates using AES-256 and ECDSA signatures - validated in standalone mode without host PC dependency.

Can the on-board energy meter measure sub-microamp currents accurately?

Yes. The dedicated energy meter circuit achieves ±0.5% accuracy across its full 300 nA–150 mA range, with auto-ranging and calibrated shunt sensing. Measurement data is streamed via a dedicated USB interface to host tools like ST's PowerSDK, enabling cycle-accurate current profiling of STOP2 and shutdown modes.

Is the LCD module usable without external drivers or timing configuration?

Yes. The 1.54" 240×240 RGB TFT is directly driven via the MCU's LTDC peripheral in parallel 8080 mode. Pre-integrated initialization code and touch calibration are included in the STM32CubeL5 demonstration firmware, enabling immediate display rendering and resistive touch response without custom register programming.

What debug interfaces does the ST-LINK-V3E provide simultaneously?

The ST-LINK-V3E delivers three concurrent interfaces over a single USB Type-C connection: Mass Storage Class (for drag-and-drop firmware loading), Virtual COM Port (for printf-based debugging and UART log streaming), and SWD/JTAG (for full breakpoint, memory inspection, and real-time variable watch in IDEs like STM32CubeIDE or IAR EWARM).
