Product details
Overview
STM32H743AII6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M7 microcontroller operating at up to 480 MHz, featuring 2 MB flash, 1 MB RAM (including 192 KB TCM), and dual-domain power management (D1/D2/D3). It integrates triple PLLs, hardware JPEG codec, LCD-TFT controller, and supports CAN FD, Ethernet MAC, and USB OTG HS/FS - deployed in industrial HMI and real-time motor control systems.
For engineers reviewing the STM32H743AII6TR datasheet, STM32H743AII6TR pinout, STM32H743AII6TR application, or STM32H743AII6TR equivalent, key selection criteria include TFBGA100 package compatibility, 480 MHz M7 core timing margin, dual-bank flash read-while-write capability, and D3 domain RTC+backup SRAM retention under VBAT.
Technical Context
The device implements a three-domain power architecture (D1 high-performance, D2 communication/timers, D3 reset/clock/power), enabling selective clock gating and independent voltage scaling across six configurable ranges. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, supporting concurrent high-bandwidth peripheral access.
It features three PLLs - one system clock PLL with fractional mode, plus two kernel-clock PLLs - feeding a hierarchical clock tree that drives 22 timers (including 2.1 ns-resolution HRTIM), dual 16-bit DACs (1 MHz), and three 16-bit ADCs (3.6 MSPS, 36-channel mux). The MDMA controller enables linked-list DMA transfers for offloading CPU-intensive data movement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance Arm Cortex-M7 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | LQFP100 package (14 × 14 mm), same core/peripherals but different thermal profile and PCB routing constraints | Suitable for through-hole prototyping or legacy board layouts requiring leaded packages | Select when mechanical compatibility with existing LQFP footprints is required; TFBGA offers higher I/O density and lower inductance. |
| STM32H753BIT6 | Same TFBGA100 package, adds cryptographic accelerator (AES-GCM, SHA-256, PKA) and larger 2 MB SRAM (vs. 1 MB) | Required for TLS 1.3 handshakes, secure boot verification, or real-time encrypted video streaming | Choose when hardware crypto offload and deterministic memory latency outweigh cost premium over H743. |
Compared with STM32H743VIT6, the AII6TR's TFBGA100 enables finer-pitch routing and better high-speed signal integrity; versus STM32H753BIT6, it trades crypto acceleration for lower BOM cost and identical real-time control latency in motor and HMI use cases.

FAQ
What is the maximum operating frequency of the STM32H743AII6TR's Cortex-M7 core?
The STM32H743AII6TR's Arm Cortex-M7 core operates at up to 480 MHz, validated across the full temperature range (–40°C to +85°C) and supply voltage (1.62–3.6 V). This frequency is achieved using the internal HSI oscillator or external HSE, with PLL configuration supporting fractional multiplication to avoid integer-only clock dividers.
Does the STM32H743AII6TR support hardware-accelerated cryptography?
No, the STM32H743AII6TR does not include a dedicated cryptographic accelerator. It lacks AES, SHA, or PKA engines found in the STM32H753/H750 variants. Security relies on software libraries or external secure elements; ROP and PC-ROP provide basic code protection but no hardware cipher acceleration.
How many I/O pins are available in the TFBGA100 package of this MCU?
The STM32H743AII6TR in TFBGA100 provides 88 general-purpose I/O pins, each supporting interrupt capability, multiple alternate functions, and configurable pull-up/pull-down resistors. Four pins are reserved for VCAP decoupling, and four for debug (SWD/JTAG), leaving 88 user-accessible GPIOs mapped across GPIO ports A–K.
What is the minimum supply current in Standby mode with RTC and LSE enabled?
In Standby mode with RTC and LSE running and Backup SRAM disabled, the STM32H743AII6TR draws a typical current of 2.95 µA at 3.3 V and 25°C. This value is measured per datasheet DS12110 Rev 11 Section 6.3.7 and includes leakage from D3 domain regulators and LSE oscillator circuitry.
