Product details
Overview
STM32F427IGH6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 180 MHz (225 DMIPS), featuring 2 MB flash memory, 256+4 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 medical devices requiring real-time processing and rich peripheral integration.
For engineers reviewing the STM32F427IGH6TR datasheet, STM32F427IGH6TR pinout, STM32F427IGH6TR application, or STM32F427IGH6TR equivalent, key selection considerations include its UFBGA176 package, 168 I/Os (166 5 V-tolerant), triple 12-bit ADCs (7.2 MSPS interleaved), LCD-TFT controller support, and ART Accelerator™ enabling zero-wait-state execution from flash.
Technical Context
The device 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 dual USB controllers (OTG_FS + OTG_HS with dedicated DMA), IEEE 1588v2-capable Ethernet MAC, and a flexible external memory controller supporting SDRAM, NOR/NAND, and PSRAM - enabling complex connectivity and display subsystems in single-chip designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance ARM Cortex-M4 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F429IGT6 | Same package (LQFP176), identical core/peripherals, but adds LCD-TFT controller (LTDC) and Chrom-ART Accelerator™ | Required for direct RGB/TFT panel driving without external controller; unnecessary if display handled externally | Select STM32F429IGT6 only when native TFT-LCD interface is needed; otherwise STM32F427IGH6TR offers cost and BOM simplification |
| STM32F437VIT6 | LQFP100 package (64 I/Os), same flash/SRAM, but lacks Ethernet MAC and USB OTG HS; retains dual CAN and FMC | Suitable for space-constrained, lower-I/O designs where Ethernet/HS USB are not required | Choose STM32F437VIT6 for compact form factor and reduced PCB layer count; trade-off is loss of high-speed connectivity and 104 fewer I/Os |
Compared with STM32F429IGT6, STM32F427IGH6TR saves cost and layout area by omitting LTDC while retaining full Ethernet, USB HS, and FMC capability; versus STM32F437VIT6, it delivers 74 additional I/Os and integrated 100BASE-TX PHY support - critical for industrial gateway scalability.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32F427IGH6TR 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 under conditions of ART Accelerator™ enabled, zero-wait-state flash execution, and includes FPU overhead. The core supports SIMD and DSP instructions for accelerated signal processing.
Does this part include hardware support for IEEE 1588 Precision Time Protocol?
Yes - the integrated 10/100 Ethernet MAC includes full IEEE 1588v2 hardware timestamping capability, supporting both one-step and two-step clock synchronization modes. Timestamp resolution is 1 ns, with hardware capture on PTP event frames (Sync, Delay_Req, Pdelay_Req, Pdelay_Resp) without CPU intervention.
What are the key differences between STM32F427IGH6TR and STM32F429IGH6TR?
The STM32F429IGH6TR adds an integrated LCD-TFT controller (LTDC) and Chrom-ART Accelerator™ (DMA2D) for direct RGB panel driving and 2D graphics acceleration. Otherwise, both share identical core, memory, USB OTG HS/FS, Ethernet MAC, dual CAN, ADC/DAC, and FMC specifications. The F427 variant omits LTDC to reduce cost and power in non-display applications.
Is the UFBGA176 package RoHS and REACH compliant?
Yes - STM32F427IGH6TR is manufactured in an ECOPACK2-compliant process, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 requirements. The UFBGA176 package uses lead-free solderable terminations and halogen-free molding compound, with full material declarations available in ST's official compliance documentation.
