Product details
Overview
STM32F412RGY6PTR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 1 MB Flash, 256 KB SRAM, USB OTG FS, dual CAN 2.0B, and 17 communication interfaces. It operates up to 100 MHz, delivers 125 DMIPS, and integrates a 12-bit 2.4 MSPS ADC, DFSDM, PDM audio interfaces, and ART Accelerator™ for zero-wait-state flash execution - deployed in industrial PLCs, medical sensor hubs, and wearable devices.
For engineers reviewing the STM32F412RGY6PTR datasheet, STM32F412RGY6PTR pinout, STM32F412RGY6PTR application, or STM32F412RGY6PTR equivalent, key selection criteria include its WLCSP64 package footprint, 100 MHz real-time performance with BAM and ART Accelerator, dual CAN support, low-power Stop mode (18 µA), and integrated USB OTG FS PHY - all critical for space-constrained, battery-aware embedded control designs.
Technical Context
The device implements an Arm Cortex-M4 core with hardware FPU and DSP instructions, paired with ST's Adaptive Real-Time Accelerator (ART Accelerator™) enabling deterministic 100 MHz execution from Flash. Its memory subsystem includes 1 MB of embedded Flash with ECC, 256 KB SRAM, flexible FSMC for external NOR/PSRAM, and dual-mode Quad-SPI for high-speed serial memory expansion.
Peripherals are organized around a multi-AHB bus matrix supporting concurrent access: two independent CAN 2.0B controllers, four I²C (SMBus/PMBus), five SPI/I²S (two full-duplex I²S), SDIO, USB OTG FS with integrated PHY, and a dedicated DFSDM with four PDM inputs for stereo microphone preprocessing - all accessible via up to 114 5V-tolerant GPIOs clocked at 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU and DSP extensions - enables floating-point math and signal processing in real-time control loops. |
| Max Clock Frequency | 100 MHz - supports deterministic timing-critical tasks like motor commutation or audio sampling at 48 kHz with low jitter. |
| Flash Memory | 1 MB with ECC - provides robust firmware storage for complex applications requiring secure boot and field updates. |
| SRAM | 256 KB - sufficient for real-time buffers, audio sample queues, and RTOS kernel + application stack. |
| ADC | 1 × 12-bit, 2.4 MSPS, 16-channel - captures fast analog transients (e.g., current sensing in inverters) with minimal latency. |
| Low-Power Stop Mode | 18 µA (typical, 25 °C, Deep Power Down) - extends battery life in always-on sensor nodes without compromising wakeup responsiveness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F413RGV6 | Same package and pinout; adds 16 KB CCM RAM, AES crypto engine, and Chrom-ART accelerator. | Better suited for GUI-rich HMI or encrypted firmware update use cases. | Select when cryptographic acceleration or enhanced graphics rendering is required - not drop-in for existing STM32F412RGY6PTR designs. |
| STM32F407VGT6 | LQFP100 package; no DFSDM, no PDM, lower max ADC speed (2.4 MSPS → 2.0 MSPS), no BAM. | Targeted at general-purpose industrial control where audio/sensor hub features are unnecessary. | Choose for cost-sensitive, non-audio applications needing larger pin count and legacy ecosystem compatibility. |
Compared with STM32F413RGV6, STM32F412RGY6PTR trades crypto and CCM RAM for smaller WLCSP footprint and lower static power; versus STM32F407VGT6, it offers superior audio preprocessing and ultra-low-power modes but requires layout adaptation due to ball-grid packaging.

FAQ
What is the maximum operating temperature range for STM32F412RGY6PTR?
The STM32F412RGY6PTR is qualified for industrial temperature range: –40 °C to +85 °C. Its thermal characteristics (θJA = 210 °C/W for WLCSP64) and internal thermal monitoring ensure reliable operation under sustained load in enclosed enclosures, validated per JEDEC JESD51-2.
Does STM32F412RGY6PTR support external memory expansion?
Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting 8-/16-bit parallel interfaces to SRAM, PSRAM, and NOR flash. The controller maps external memory into the Cortex-M4's unified address space, enabling XIP execution and DMA-accessible buffers without software overhead.
How does the Batch Acquisition Mode (BAM) reduce power consumption?
BAM allows peripherals like ADC, DFSDM, or UART to autonomously acquire and buffer data while the CPU remains in Stop mode. Upon completion, only one wakeup event triggers CPU execution - reducing active time by up to 40% in periodic sensor polling, as confirmed in ST's AN4989 application note.
Is the USB OTG FS interface fully self-contained?
Yes - the USB OTG FS peripheral includes an integrated PHY, eliminating external transceivers. It supports device, host, and OTG roles with full-speed (12 Mbps) operation, on-chip USB voltage regulator, and VBUS sensing - verified in ST's UM1723 reference manual and hardware validation reports.
