STM32H743BIT6 Detailed explanation of pin function specifications and circuit principle instructions

The STM32H743BIT6 is a microcontroller from STMicroelectronics, part of the STM32H7 series. This series is known for its high-performance ARM Cortex-M7 cores. The "STM32H743BIT6" specifically refers to a particular model within this series, where the "H7" indicates the high-performance series, "43" denotes the family, "B" indicates the package type, "IT" refers to the temperature range and specific variants, and "6" is for the pin count.

Here’s a breakdown of the detailed specifications you requested:

1. Package Type & Pin Count

The STM32H743BIT6 is in a LQFP (Low-profile Quad Flat Package), and it typically comes with 176 pins. However, to clarify, there are variants of the STM32H743 series with different pin counts, and you mentioned 200 pins, which is incorrect for this particular model. The STM32H743BIT6 is available in a 176-pin package, which is more common for this series.

2. Pin Functionality

I will provide the function descriptions for all 176 pins of the STM32H743BIT6 in a tabular format.
