Product details
Overview
STM32F412RGY6TR 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 STM32F412RGY6TR datasheet, STM32F412RGY6TR pinout, STM32F412RGY6TR application, or STM32F412RGY6TR equivalent, key selection criteria include Flash/SRAM size, dual-CAN support, low-power Stop mode (18 µA), 100 MHz timing headroom, and UFBGA64 package compatibility with high-density PCB layouts.
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 100 MHz execution from Flash. Its memory subsystem includes flexible external static memory controller (FSMC) supporting NOR/PSRAM and dual-mode Quad-SPI for XIP-capable serial flash.
Peripherals are organized around a multi-AHB bus matrix with dedicated DMA streams (16-channel general-purpose DMA), enabling concurrent high-bandwidth transfers for ADC, audio (I2S/PDM), USB OTG FS, and SDIO without CPU intervention - critical for real-time sensor fusion and connected-object applications.
Key Specifications

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, +128 KB SRAM (384 KB total), added AES crypto accelerator and Chrom-ART GPU | Better suited for GUI-rich HMI or encrypted data pipelines; higher BOM cost | Select when display rendering or AES-128 encryption is required beyond baseline F412 capabilities. |
| STM32F407VGT6 | LQFP100 package, no DFSDM/PDM, lower max clock (168 MHz but no ART on larger Flash), no BAM | Legacy design continuity for existing LQFP-based boards; lacks modern low-power audio features | Choose only for drop-in replacement in legacy F407 designs where UFBGA64 footprint and audio features are not needed. |

FAQ
What is the maximum operating temperature range for STM32F412RGY6TR?
The STM32F412RGY6TR is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 (General operating conditions) of DS11139 Rev 9, with validated performance including 18 µA Stop mode current and 100 MHz operation across the full range.
Does STM32F412RGY6TR support external SDRAM via FSMC?
No - the Flexible Static Memory Controller (FSMC) supports only NOR flash, PSRAM, and SRAM with address/data multiplexing. SDRAM requires dedicated SDRAM controller logic not present in the F412 series; this is explicitly omitted from Table 2 (peripheral counts) and Section 3.11 of the datasheet.
Can PA11/PA12 be used for USB device mode without external components?
Yes - PA11 (USB_DM) and PA12 (USB_DP) connect directly to the integrated USB OTG FS transceiver. No external PHY or termination resistors are required for basic full-speed device operation, as verified in Section 3.32 and Figure 13 (USB OTG FS block diagram) of DS11139 Rev 9.
Is the 96-bit unique ID accessible via standard debug interface?
Yes - the 96-bit unique ID is readable via the DBGMCU_IDCODE register (address 0xE0042000) using SWD or JTAG. It is factory-programmed, non-erasable, and documented in Section 3.39 (Unique device identifier) and Table 12 (register boundary addresses) of the datasheet.
