Evaluation board with STM32L476ZGT6 MCU

Introduction

The STM32L476G-EVAL evaluation board is designed as complete demonstration and 
development platform for STMicroelectronics ARM

®

 Cortex

®

-M4-core-based 

STM32L476ZGT6 microcontroller with three I²C buses, three SPI and six USART ports, 
CAN port, SWPMI, two SAI ports, 12-bit ADC, 12-bit DAC, LCD driver, internal 128-Kbyte 
SRAM and 1-Mbyte Flash memory, Quad-SPI port, touch sensing capability, USB OTG FS 
port, LCD controller, flexible memory controller (FMC), JTAG debug port.

 

STM32L476G-EVAL, shown in 

Figure 1

(1)

, can be used as reference design for user 

application development, although it is not considered as final application.

A full range of hardware features on the board helps users evaluate all on-board peripherals 
such as USB, USART, digital microphones, ADC and DAC, dot-matrix TFT LCD, LCD glass 
module, IrDA, LDR, SRAM, NOR Flash memory device, Quad-SPI Flash memory device, 
microSD card, sigma-delta modulators, smartcard with SWP, CAN transceiver, EEPROM, 
RF-EEPROM. Extension headers allow connecting daughterboards or wrapping boards.

ST-LINK/V2-1 in-circuit debugger and flashing facility is integrated on the mainboard.
