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 2 controller, two SAI ports, four I C buses, six USART ports, three SPI interfaces, one CAN FD controller, one SDMMC interface, two 12-bit ADC, two 12-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 2 modulators, smartcard, CANFD transceiver, I C, EEPROM), and to 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. DB3617 - Rev 2 page 2/6
