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.
