Product details
Overview
STM32L552E-EV from STMicroelectronics is an evaluation board built around the STM32L552ZET6QU ultra-low-power Arm® Cortex®-M33 microcontroller with TrustZone® security, featuring 512 KB Flash, 256 KB SRAM, Octo-SPI, HyperRAM, USB Type-C™ FS with PD controller, and dual-channel sigma-delta modulator for power metering.
For engineers reviewing the STM32L552E-EV datasheet, STM32L552E-EV pinout, STM32L552E-EV application, or STM32L552E-EV equivalent, this board supports full peripheral validation-including TFT LCD with touch, SAI audio codec, ST-MEMS microphones, CAN FD, RS-232, Smartcard, microSD™, and multiple expansion interfaces (STMod+, Pmod™, motor-control, audio daughterboard).
Technical Context
The board implements a complete reference design for secure, low-power embedded applications using Armv8-M architecture with TrustZone®, enabling hardware-isolated secure and non-secure firmware execution. It integrates dual 12-bit ADCs, two 12-bit DACs, two op-amps, four sigma-delta digital filters, and hardware cryptographic accelerators (AES-256, PKA, RNG).
It provides parallel-interface 2.8" 240×320 TFT LCD with resistive touch panel, on-board ST-LINK/V2-1 debugger supporting SWD/JTAG/ETM trace, and flexible power routing via USB VBUS, ST-LINK, or external supply with on-board current measurement capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm® Cortex®-M33 with TrustZone® - enables secure boot, isolated execution environments, and hardware-enforced memory protection |
| MCU Package | LQFP144 - standard surface-mount package with 144 pins, compatible with industrial reflow profiles and prototyping |
| Memory | 512 KB Flash + 256 KB SRAM - sufficient for complex RTOS-based applications with secure/non-secure partitioning |
| Display Interface | Parallel RGB 8080 - drives 240×320 262K-color TFT LCD directly without external video controller |
| External Memory | 512-Mbit Octal-SPI Flash + 64-Mbit Octal HyperRAM + 16-Mbit SRAM - enables high-speed code/data offload and graphics buffer storage |
| Connectivity | CAN FD + RS-232 + USB Type-C™ FS + SDMMC + Smartcard socket - supports industrial communication, legacy serial, secure card reading, and removable storage |
| Debug Interface | Integrated ST-LINK/V2-1 - provides SWD/JTAG/ETM trace, Virtual COM port, and mass storage programming without external tools |

FAQ
Does STM32L552E-EV support CAN FD communication?
Yes. The board includes a dedicated CAN FD transceiver connected to the STM32L552ZET6QU's CAN FD controller, with DB9 connector and termination resistors pre-installed. It supports data rates up to 5 Mbps and frame payloads up to 64 bytes, validated using ST's X-CUBE-CANFD software stack and included demonstration firmware.
What display resolution and interface does the onboard LCD support?
The board integrates a 2.8-inch TFT LCD with 240 × 320 pixel resolution and 262K-color depth, driven via 16-bit parallel RGB 8080 interface. Touch functionality uses resistive overlay with dedicated ADC channels and calibration firmware in STM32CubeL5 examples.
Is ST-LINK/V2-1 debugger accessible for external target programming?
Yes. The on-board ST-LINK/V2-1 can be configured as an external programmer/debugger via solder bridges SB12–SB15. When disconnected from the onboard MCU, it exposes SWDIO, SWCLK, NRST, and GND pins on the CN4 debug header, fully compatible with STM32CubeProgrammer and third-party IDEs.
Can the board run power metering demonstrations out of the box?
Yes. It includes dual-channel sigma-delta modulators (SDM) with anti-aliasing filters and dedicated digital filters, preloaded with power-metering demo firmware. The LDR, potentiometer, and coin-cell backup enable real-time voltage/current sampling, RMS calculation, and energy logging to HyperRAM or microSD™.
