Product details
Overview
STM32F412ZGJ6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max clock, 1 MB Flash, 256 KB SRAM, and USB OTG FS controller. It integrates dual CAN 2.0B interfaces, 17 communication peripherals including 4x I²C, 4x USART, 5x SPI/I²S, SDIO, and advanced analog features including a 12-bit 2.4 MSPS ADC and DFSDM for PDM microphone input - deployed in industrial PLCs, medical sensor hubs, and connected wearable devices.
For engineers reviewing the STM32F412ZGJ6TR datasheet, STM32F412ZGJ6TR pinout, STM32F412ZGJ6TR application, or STM32F412ZGJ6TR equivalent, key selection criteria include Flash/SRAM capacity, dual-CAN support, low-power Stop mode current (18 µA), ART Accelerator™-enabled zero-wait-state execution, and UFBGA144 package compatibility with high I/O count (114 pins, 109 at 100 MHz).
Technical Context
The device implements an Arm Cortex-M4 core with hardware FPU and DSP instruction set, 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 of embedded Flash with ECC, 256 KB SRAM, flexible FSMC for NOR/PSRAM, and dual-mode Quad-SPI for external memory expansion.
Peripherals are organized around a multi-AHB bus matrix supporting concurrent access: two independent CAN 2.0B controllers, USB OTG FS with integrated PHY, 17 timers (including two 32-bit general-purpose timers), and a dedicated digital filter for sigma-delta modulators (DFSDM) with four PDM interfaces for stereo audio acquisition - all operating across 1.7–3.6 V supply range with sub-µA RTC backup capability.

FAQ
What is the maximum operating temperature range for STM32F412ZGJ6TR?
The STM32F412ZGJ6TR is specified for industrial temperature range: –40 °C to +85 °C ambient. Electrical characteristics including Flash programming voltage, ADC accuracy, and CAN timing remain guaranteed across this range per DS11139 Rev 9 Section 6.3.1. Thermal derating is not required below 105 °C junction temperature.
Does STM32F412ZGJ6TR support external memory interfaces beyond Quad-SPI?
Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting 8-/16-bit parallel interfaces to SRAM, PSRAM, NOR flash, and LCD panels in 8080/6800 modes. This enables direct connection to external displays or legacy memory without glue logic, unlike Quad-SPI which is serial-only and limited to flash-type devices.
How many independent CAN controllers does STM32F412ZGJ6TR include?
The STM32F412ZGJ6TR integrates two fully independent bxCAN 2.0B controllers (CAN1 and CAN2), each with its own message RAM, filter banks, and clock domain. They operate concurrently without resource contention, supporting dual-network applications such as CAN-based motor control plus diagnostics bus in medical equipment.
Is the USB OTG FS interface on STM32F412ZGJ6TR self-powered or bus-powered?
The USB OTG FS interface includes an integrated PHY with internal transceivers and supports both device and host roles. It operates in bus-powered mode when acting as a USB device and can supply up to 8 mA to downstream ports in host mode - no external VBUS detection or power switch IC is required for basic enumeration and data transfer.
