STMicroelectronics STM32F412ZGJ6

Overview

STM32F412ZGJ6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max clock, 1 MB Flash, 256 KB SRAM, and integrated USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It delivers 125 DMIPS performance and supports advanced low-power modes (down to 2.4 µA in Standby), making it suitable for battery-powered sensor hubs and industrial edge controllers requiring real-time signal processing and connectivity.

For engineers reviewing the STM32F412ZGJ6 datasheet, STM32F412ZGJ6 pinout, STM32F412ZGJ6 application, or STM32F412ZGJ6 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU core, dual CAN support, 1 MB flash density, 12-bit 2.4 MSPS ADC with up to 16 channels, and UFBGA144 (10×10 mm) package with 114 I/Os - all critical for motor control, medical instrumentation, and connected object designs.

Technical Context

The STM32F412ZGJ6 integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, and features Batch Acquisition Mode (BAM) for ultra-low-power peripheral data capture without CPU wake-up. Its memory subsystem includes flexible static memory controller (FSMC) supporting NOR/PSRAM and dual-mode Quad-SPI for external flash expansion.

It implements a full-featured clock tree with four oscillators (4–26 MHz HSE, 32 kHz LSE, 16 MHz HSI, 32 kHz LSI), multiple PLLs (including audio PLL for I2S), and independent power domains for RTC and VBAT. The peripheral set includes two DFSDM modules for sigma-delta filtering, four PDM interfaces, stereo microphone support, and hardware CRC unit - optimized for audio preprocessing and secure firmware integrity verification.

FAQ

What is the maximum operating frequency and core type of the STM32F412ZGJ6?

The STM32F412ZGJ6 features an Arm Cortex-M4 core with integrated FPU, operating at up to 100 MHz. It achieves 125 DMIPS performance (1.25 DMIPS/MHz) per Dhrystone 2.1 benchmark. The ART Accelerator™ enables zero-wait-state execution from Flash memory, ensuring deterministic timing for real-time control tasks without external SRAM dependency.

Does the STM32F412ZGJ6 support USB device, host, and OTG functionality?

Yes, the STM32F412ZGJ6 integrates a full-speed USB 2.0 OTG controller with integrated PHY, supporting device, host, and On-The-Go operation. It complies with USB 2.0 specification and includes dedicated USB-specific interrupts, endpoint buffers, and VBUS sensing - enabling seamless firmware updates via USB mass storage class or bridging to external peripherals like printers or BLE adapters.

How many CAN interfaces does the STM32F412ZGJ6 include, and what version do they support?

The STM32F412ZGJ6 includes two independent bxCAN 2.0B controllers, each supporting both standard (11-bit) and extended (29-bit) identifier formats, bit rates up to 1 Mbit/s, and programmable message filters. These controllers operate concurrently and share no resource contention, allowing simultaneous use in multi-bus industrial networks or redundant safety architectures.

What low-power modes are available, and what is the lowest achievable current draw?

The STM32F412ZGJ6 supports Run, Sleep, Stop, and Standby modes. In Standby mode with RTC disabled and VDD = 1.7 V, typical current consumption is 2.4 µA at 25 °C. With RTC enabled and VBAT supplied, standby current rises to 12 µA at 85 °C. Deep Stop mode with Flash in Deep Power Down achieves 18 µA typical at 25 °C - ideal for infrequent wake-up sensor monitoring.
