Evaluation board with STM32F446ZE MCU

The STM32446E-EVAL evaluation board has been designed as a complete demonstration and development platform for the STMicroelectronics ARM® Cortex®-M4 with FPU core-based STM32F446ZET6 microcontroller with SPDIF input, four I2C, four SPI, three I2S, two SAI, two CAN, three 12-bit ADC, two 12-bit DAC, up to 17 timers, USB OTG HS and FS, camera interface, FMC and QuadSPI interfaces, SDIO interface, 512KB Flash memory and 128KB SRAM, JTAG and ETM trace debugging support.

The full range of hardware features on the board can be used to evaluate all peripherals (USB HS & FS, USART, IrDA, CAN, digital microphones, audio codec, ADC and DAC, color LCD glass with touchscreen, SDRAM and QuadSPI Flash memories, I2C EEPROM, RF EEPROM, MicroSD card) and develop user’s applications. Extension headers make it possible to easily connect a daughter board specific application.

An ST-LINK/V2-1 is integrated on the board, as embedded in-circuit debugger and programmer for the STM32 MCU.
