概述

Description

STM32F446MEY6TR is an STM32F4 family microcontroller from STMicroelectronics. It uses the ARM Cortex-M4 core with a hardware floating-point unit and DSP instructions, and runs up to about 180 MHz. The device family provides flash and RAM sizes that vary by variant; check the exact datasheet for the MEY6TR part. It offers a broad set of peripherals suitable for embedded control and multimedia, including serial interfaces (USART/UART, SPI, I2C), USB OTG, CAN, SDIO, multiple timers, ADCs, DAC, DMA, CRC, RNG, and often LCD/TFT support depending on package. The MEY6 suffix encodes the specific package, temperature range, and packaging (TR = tape and reel). This MCU is well-suited for motor control, USB-enabled devices, audio/video, and display applications. For precise specifications—memory sizes, available pins, and per‑pin capabilities—refer to the official STM32F446 datasheet, reference manual, and the product page. If you want, I can pull the exact numbers for MEY6TR.
