STMicroelectronics STM32F427VIT6

Overview

STM32F427VIT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 180 MHz (225 DMIPS), featuring 1 MB flash, 256 KB SRAM + 4 KB backup SRAM, and integrated USB OTG HS/FS, 10/100 Ethernet MAC, and dual CAN 2.0B interfaces. It targets high-performance industrial control, motor drives, and embedded vision systems requiring real-time processing, connectivity, and graphics acceleration.

For engineers reviewing the STM32F427VIT6 datasheet, STM32F427VIT6 pinout, STM32F427VIT6 application, or STM32F427VIT6 equivalent, key selection criteria include its 100-pin LQFP package, 180 MHz CPU clock, dual CAN + Ethernet + USB OTG HS support, LCD-TFT controller capability (shared with F429 series but disabled in F427), and ART Accelerator™ enabling zero-wait-state execution from flash.

Technical Context

The STM32F427VIT6 implements an Arm Cortex-M4 core with hardware FPU and Memory Protection Unit (MPU), paired with ST's Adaptive Real-Time Accelerator (ART Accelerator™) for deterministic flash execution. Its multi-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without contention.

It integrates a flexible external memory controller (FMC) supporting SDRAM, NOR/NAND, and PSRAM; a 12-bit, 2.4 MSPS ADC (triple interleaved up to 7.2 MSPS); two 12-bit DACs; and a true random number generator (RNG). Debug is supported via SWD and JTAG with Cortex-M4 Trace Macrocell™.

FAQ

Is STM32F427VIT6 pin-compatible with STM32F429VIT6?

Yes - both use identical LQFP100 packages and share full pin-to-pin compatibility across all I/Os, power, clock, and debug signals. The only functional difference is that the F427 disables the LTDC and related RGB interface pins (e.g., R/G/B lines, HSYNC, VSYNC), which remain NC or repurposed as GPIOs.

Does STM32F427VIT6 support USB OTG High-Speed operation?

Yes - it integrates a dedicated USB OTG HS controller with on-chip full-speed PHY and ULPI interface, supporting 480 Mbps operation when paired with an external HS transceiver. The internal FS PHY handles full-speed (12 Mbps) directly without external components.

What is the maximum operating temperature for STM32F427VIT6?

The STM32F427VIT6 is rated for industrial temperature range: –40°C to +105°C ambient. This is validated per ST's DS9405 specification and confirmed in Section 6.3.1 (General Operating Conditions) of the official datasheet Rev 13.

Can the FMC interface drive DDR SDRAM?

No - the Flexible Memory Controller (FMC) supports SDR SDRAM (single-data-rate), PSRAM, NOR, NAND, and SRAM, but does not support DDR (double-data-rate) SDRAM due to lack of differential clock and bidirectional DQS strobe handling. Use external DDR controller ICs or migrate to STM32H7-series for DDR support.
