Product details

Overview

STM32F412ZGT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max CPU frequency, 1 MB Flash, 256 KB SRAM, and integrated USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It delivers 125 DMIPS and supports real-time motor control, sensor hub processing, and industrial HMI in compact LQFP144 packages.

For engineers reviewing the STM32F412ZGT6TR datasheet, STM32F412ZGT6TR pinout, STM32F412ZGT6TR application, or STM32F412ZGT6TR equivalent, key selection criteria include Flash/SRAM size, USB OTG + dual CAN integration, low-power Stop mode (18 µA), ART Accelerator™ for zero-wait-state flash execution, and LQFP144 package compatibility with industrial PCB layouts.

Technical Context

The device implements an Arm Cortex-M4 core with hardware FPU and DSP instructions, coupled with ST's Adaptive Real-time Accelerator (ART Accelerator™) enabling deterministic 0-wait-state execution from Flash at 100 MHz. Its memory subsystem includes 1 MB Flash with ECC support, 256 KB SRAM, flexible FSMC for NOR/PSRAM, and dual-mode Quad-SPI.

Peripherals are organized around a multi-AHB bus matrix: two 32-bit general-purpose timers (100 MHz), 12×16-bit timers, dual CAN 2.0B controllers, USB OTG FS with embedded PHY, SDIO, four I²C, four USART (two up to 12.5 Mbit/s), five SPI/I²S, and a 12-bit 2.4 MSPS ADC with up to 16 channels - all accessible via 114 I/Os (109 at 100 MHz, 114 5V-tolerant).

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F413ZGT6	Same LQFP144 package, adds AES-256 crypto engine and Chrom-ART accelerator; 1 MB Flash, 320 KB SRAM.	Better suited for secure boot, encrypted firmware updates, and GUI rendering with hardware acceleration.	Select when cryptographic security or TFT-LCD graphics performance is required beyond STM32F412ZGT6TR's capabilities.
STM32F407VGT6	LQFP100 package; 1 MB Flash, 192 KB SRAM; lacks USB OTG FS PHY, DFSDM, and BAM; retains dual CAN and similar timer/peripheral count.	Lower I/O count and no embedded USB PHY require external transceiver; less optimized for ultra-low-power sensor aggregation.	Choose for cost-sensitive designs where USB host functionality is unnecessary and 100-pin footprint suffices.

Compared with STM32F413ZGT6, the STM32F412ZGT6TR trades crypto/GUI acceleration for lower power in Stop mode (18 µA vs. 25 µA) and integrated USB PHY - making it preferable for battery-powered industrial edge nodes. Versus STM32F407VGT6, it adds USB OTG FS with PHY and BAM while upgrading SRAM to 256 KB, justifying use in USB-connected sensor hubs and compact HMI controllers.

FAQ

What is the maximum operating temperature range for STM32F412ZGT6TR?

The STM32F412ZGT6TR is specified for industrial temperature range: –40 °C to +85 °C ambient. Electrical characteristics including Flash programming voltage, ADC accuracy, and oscillator stability are guaranteed across this range, with thermal derating applied above 70 °C for sustained high-current I/O operation.

Does STM32F412ZGT6TR support external memory interfaces beyond FSMC?

Yes - in addition to the Flexible Static Memory Controller (FSMC) supporting NOR, PSRAM, and LCDs, the device features a dual-mode Quad-SPI interface capable of XIP (execute-in-place) from external serial flash, reducing boot time and simplifying firmware updates without requiring external parallel memory.

Can the USB OTG FS interface operate in host-only mode without device capability?

No - the USB OTG FS controller is fully compliant with USB On-The-Go specification and supports device, host, and OTG roles dynamically via ID pin detection and session request protocol (SRP). Host-only operation requires external VBUS sensing and power switching circuitry but is fully supported in firmware.

How many independent clock sources does STM32F412ZGT6TR provide for system redundancy?

The MCU integrates four independent clock sources: 4–26 MHz HSE crystal oscillator, 16 MHz factory-trimmed HSI RC, 32.768 kHz LSE for RTC, and 32 kHz LSI RC - enabling failover clocking, RTC backup, and low-power wake-up without external components.
