STM32L552E-EV
Description
The STM32L552E-EV Evaluation board is designed as a complete demonstration
and development platform for STMicroelectronics Arm® Cortex®-M33 core with
TrustZone® and the ARMv8-M mainline security extension.
The STM32L552E-EV Evaluation board is based on an ultra-low-power
STM32L552ZET6QU microcontroller with 512 Kbytes of Flash memory and
256 Kbytes of SRAM, one external memory interface supporting an LCD interface,
one Octo-SPI memory interface, one USB Type-C™ FS with Power Delivery
controller, two SAI ports, four I²C buses, six USART ports, three SPI interfaces, one
CAN FD controller, one SDMMC interface, 2x12-bit ADC, 2x12-bit DAC, two
operational amplifiers, two ultra-low comparators, four digital filters for sigma-delta
modulator, up to 16 timers, touch-sensing capability, and debugging supported by
SWD, JTAG and ETM interface.
The full range of hardware features on the board helps the user to evaluate all the
peripherals (USB FS, USART, digital microphones, ADC and DAC, dot-matrix TFT
LCD, LDR, SRAM, octal Flash memory device, microSD™ card, sigma-delta
modulators, smartcard, CAN FD transceiver, I²C, EEPROM), and develop
applications. Extension headers allow easy connection of a daughterboard or
wrapping board for a specific application.
An ST-LINK/V2-1 is integrated on the board, as embedded in-circuit debugger and
programmer for the STM32 MCU and the USB Virtual COM port bridge.

1.1 Product marking
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference design or in production.
“E” or “ES” marking examples of location:
• On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the STM32
datasheet “Package information” paragraph at the www.st.com website).
• Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number
and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
