Product details
Overview
STM32F427VIT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 180 MHz (225 DMIPS), featuring 1 MB flash memory, 256 KB SRAM (including 64 KB CCM), and integrated USB OTG HS/FS, 10/100 Ethernet MAC, and dual CAN 2.0B interfaces. It targets high-performance embedded applications such as industrial HMI, motor control gateways, and networked edge devices requiring real-time processing and rich peripheral integration.
For engineers reviewing the STM32F427VIT6TR datasheet, STM32F427VIT6TR pinout, STM32F427VIT6TR application, or STM32F427VIT6TR equivalent, key selection considerations include its LQFP100 package, 168 I/Os (164 at 90 MHz), triple 12-bit ADCs (2.4 MSPS each), LCD-TFT controller support (up to 4096×2048), and hardware IEEE 1588v2 Ethernet timing.
Technical Context
This MCU integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from flash at 180 MHz, alongside a Memory Protection Unit (MPU) and dual-bank flash supporting read-while-write. Its multi-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without contention.
The device features a dedicated Ethernet MAC with IEEE 1588v2 hardware timestamping, two independent USB OTG controllers (one FS-only, one HS/FS with ULPI), and a Chrom-ART Accelerator™ (DMA2D) for efficient 2D graphics composition - all coordinated via a 16-stream DMA controller with FIFO buffering and burst support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F429VIT6 | Same core, memory, and peripherals but adds LCD-TFT controller (LTDC) and Chrom-ART Accelerator™ - not present in F427 series | Required for direct RGB/TFT panel driving; unnecessary if display handled externally or via HDMI bridge | Select F429 only when native LCD-TFT interface is needed; otherwise F427 offers identical control/connectivity at lower cost |
| STM32H743VIT6 | Cortex-M7 core (480 MHz), double-precision FPU, 2 MB flash, 1 MB RAM, enhanced security (AES/SHA/PUF), and dual-core capability (Cortex-M4 + M7) | Targeted at AI-edge inference, advanced vision, or safety-critical systems requiring ASIL-B compliance and higher throughput | Choose H743 only when >225 DMIPS, dual-core isolation, or hardware crypto acceleration is required - F427 remains optimal for cost-sensitive real-time control |
Compared with STM32F429VIT6, the STM32F427VIT6TR omits LTDC but retains identical Ethernet, USB, CAN, and ADC capabilities - making it ideal for non-display-centric control nodes. Against STM32H743VIT6, it trades peak performance and security features for lower power, simpler toolchain adoption, and proven qualification in industrial deployments.

FAQ
What is the maximum operating frequency and corresponding performance metric?
The STM32F427VIT6TR operates at up to 180 MHz with a measured performance of 225 DMIPS (Dhrystone 2.1), achieving 1.25 DMIPS/MHz. This rating is validated with ART Accelerator enabled and code executed from flash memory - confirmed in ST's DS9405 Rev 13 datasheet Section 2.1 and Table 2.
Does this MCU support hardware encryption or secure boot features?
No, the STM32F427VIT6TR does not integrate hardware AES, SHA, or PUF modules. It lacks dedicated cryptographic accelerators or secure ROM-based boot loaders. Secure boot must be implemented in software using external trusted elements or via external secure EEPROM - unlike later STM32H7 or STM32L5 series.
What are the key differences between STM32F427 and STM32F429 variants?
The primary difference is the presence of the LCD-TFT controller (LTDC) and Chrom-ART Accelerator™ (DMA2D) in STM32F429 devices - absent in F427. All other core specs (CPU, memory, USB, Ethernet, CAN, ADC, timers) are identical. Pin compatibility exists within same package types (e.g., LQFP100), but LTDC-related pins are no-connection on F427.
Is the STM32F427VIT6TR qualified for automotive applications?
No, the STM32F427VIT6TR is rated for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. ST offers automotive-grade derivatives under the STM32F427xxI or STM32F427xxA suffixes with extended temperature support and additional reliability testing - this part number carries the 'T' (industrial) grade designation per ordering code conventions in DS9405 Section 8.
