Evaluation board with STM32L4R9AI MCU
Introduction
The STM32L4R9I-EVAL board is designed as complete demonstration and development
®
®
platform for the STMicroelectronics Arm
Cortex
-M4 core-based STM32L4R9AI
microcontroller with four I²C buses, three SPI and six USART ports, CAN port, two SAI
ports, 12-bit ADC, 12-bit DAC, internal 640-Kbyte SRAM and 2-Mbyte Flash memory, two
Octo-SPI memory interfaces, touch-sensing capability, USB OTG FS port, LCD-TFT
®
controller, MIPI
DSI host controller, flexible memory controller (FMC), 8- to 14-bit camera
interface and JTAG debugging support.
The STM32L4R9I-EVAL, shown in
Figure
3,
Figure
4, and
Figure
5, is used as a reference
design for user application development before porting to the final product.
The full range of hardware features on the board helps the user to evaluate all the
peripherals (USB, USART, digital microphones, ADC and DAC, TFT LCD, MIPI DSI
display, LDR, SRAM, NOR Flash memory device, Octo-SPI Flash memory device,
microSD™ card, sigma-delta modulators, CAN transceiver, 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 the embedded in-circuit debugger and
programmer for the STM32 MCU and the USB virtual COM port bridge.
