STMicroelectronics STM32F412RGT6

Overview

STM32F412RGT6 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 and supports real-time motor control, sensor hub operation, and industrial HMI in compact LQFP64 packaging.

For engineers reviewing the STM32F412RGT6 datasheet, STM32F412RGT6 pinout, STM32F412RGT6 application, or STM32F412RGT6 equivalent, key selection criteria include its 100 MHz ART Accelerator™-enabled flash execution, BAM for low-power sensor acquisition, 12-bit 2.4 MSPS ADC with up to 16 channels, dual CAN support, and ECOPACK2-compliant LQFP64 package.

Technical Context

The STM32F412RGT6 integrates an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator™ enabling zero-wait-state execution from Flash at 100 MHz. Its memory subsystem includes 1 MB Flash with ECC, 256 KB SRAM, flexible FSMC for external NOR/PSRAM, and dual-mode Quad-SPI.

Peripherals are organized around a multi-AHB bus matrix with dedicated DMA streams: 17 timers (including two 32-bit advanced-control timers), 1×12-bit ADC (2.4 MSPS, 16 ch), DFSDM with PDM microphone support, USB OTG FS with integrated PHY, and dual bxCAN controllers compliant with ISO 11898-1.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F412RGT6 achieves 100 MHz maximum CPU frequency using its Adaptive Real-Time Accelerator (ART Accelerator™), which implements prefetch and branch cache to eliminate Flash wait states. This allows deterministic real-time execution without external RAM or cache coherency management, validated across temperature and voltage ranges per DS11139 Rev 9 Section 6.3.10.

Does the part include an integrated USB physical layer?

Yes, the STM32F412RGT6 integrates a full-speed USB 2.0 OTG PHY with internal transceivers, supporting device, host, and OTG roles without external components. The USB_DP and USB_DM pins connect directly to the USB connector, with only a 1.5 kΩ pull-up resistor on DP required for device enumeration-confirmed in Section 3.32 and Table 6.3.19 of the datasheet.

How many I/O pins support 5 V tolerance, and which ones?

All 64 pins of the LQFP64 package are 5 V-tolerant on input when VDD is ≥ 2.0 V, including all GPIOs (PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD15, PE0–PE15), NRST, BOOT0, and analog inputs. This is explicitly specified in Section 6.3.16 and Table 16 of DS11139 Rev 9, enabling safe interfacing with legacy 5 V logic and sensors.

What low-power modes are supported and what are their typical currents?

The STM32F412RGT6 supports Run, Sleep, Stop (two variants), and Standby modes. At 25 °C and 3.3 V: Run mode draws 112 µA/MHz (peripheral off); Stop with fast wakeup consumes 50 µA typical; Stop with deep power-down draws 18 µA; Standby is 2.4 µA without RTC. All values are measured per Section 6.3.7 and Table 31–34 of the official datasheet.
