Product details

Overview

STM32F415RGT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 168 MHz (210 DMIPS), featuring 1 MB Flash, 192+4 KB SRAM (including 64 KB CCM), hardware crypto acceleration (AES-128/192/256, SHA-1, MD5), USB OTG HS/FS, 10/100 Ethernet MAC, and dual CAN 2.0B interfaces - deployed in industrial gateways requiring secure, high-throughput connectivity and real-time control.

For engineers reviewing the STM32F415RGT6TR datasheet, STM32F415RGT6TR pinout, STM32F415RGT6TR application, or STM32F415RGT6TR equivalent, key selection criteria include its dual USB OTG capability (HS + FS), IEEE 1588v2–enabled Ethernet MAC, triple 12-bit ADCs (7.2 MSPS interleaved), cryptographic hardware engine, and 140 GPIOs with 5 V tolerance - critical for deterministic edge-node designs.

Technical Context

The STM32F415RGT6TR integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash at 168 MHz, paired with a memory protection unit (MPU) and nested vectored interrupt controller (NVIC) for deterministic real-time response. Its multi-AHB bus matrix concurrently serves CPU, DMA, and peripherals without contention.

It features dual USB controllers: one full-speed OTG with on-chip PHY, and one high-speed OTG with dedicated DMA and ULPI interface; plus a 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping, MII/RMII support, and dedicated DMA - enabling time-sensitive networking in industrial automation.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm Cortex-M4 with FPU, 168 MHz max frequency, 210 DMIPS performance - enables real-time DSP and control algorithms without external co-processors.
Memory	1 MB Flash (0-wait-state via ART), 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM - supports large firmware images, real-time data buffering, and low-latency core-coupled variables.
Crypto Engine	Hardware AES-128/192/256, Triple DES, SHA-1, MD5, HMAC - offloads TLS handshake and secure boot verification, reducing CPU overhead by >90% vs. software-only implementation.
Analog Peripherals	Three 12-bit ADCs (2.4 MSPS each, 7.2 MSPS triple interleaved), two 12-bit DACs - suitable for multi-channel motor current sensing and closed-loop analog output control.
Connectivity	Dual CAN 2.0B, USB OTG HS/FS, 10/100 Ethernet MAC with IEEE 1588v2, SDIO, DCMI (54 MB/s) - enables concurrent fieldbus, wired IP, and camera-based HMI in single-chip edge nodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32F417VGT6	Same core/peripherals but adds LCD-TFT controller and Chrom-ART accelerator; no DCMI; 100-pin LQFP.	Better suited for HMI-focused designs with integrated display driving; lacks camera interface.	Select if TFT-LCD output is primary requirement and camera input is unnecessary.
STM32F427VIT6	Higher Flash (2 MB), adds FMC (replaces FSMC), no hardware crypto; same 100-pin LQFP.	Targeted at memory-intensive applications (e.g., protocol stacks with large buffers); lacks AES/SHA engines.	Choose when extended Flash and external SDRAM support outweigh need for on-chip crypto acceleration.

Compared with STM32F417VGT6, the STM32F415RGT6TR trades LCD capability for DCMI and crypto - making it optimal for vision-enabled, security-critical edge nodes. Against STM32F427VIT6, it sacrifices Flash capacity and FMC for certified cryptographic primitives essential in regulated IoT deployments.

FAQ

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

The STM32F415RGT6TR achieves 168 MHz via its internal PLL, driven by either the 4–26 MHz HSE crystal oscillator or the 16 MHz HSI RC oscillator. The Adaptive Real-time Accelerator (ART) ensures zero-wait-state execution from Flash memory at this frequency, validated per DS8597 Rev 9 Section 2.2.2. This enables sustained 210 DMIPS performance without external cache or SRAM acceleration.

Does this MCU support hardware-based secure boot?

Yes - the STM32F415RGT6TR includes a True Random Number Generator (RNG), hardware AES-128/192/256, and SHA-1/MD5 engines, enabling cryptographically verified secure boot. Boot code can be signed and encrypted; the ROM bootloader validates signatures using public keys stored in OTP, and decryption occurs in hardware before loading into RAM - all documented in AN4229 and RM0090.

What are the supported Ethernet physical layer interfaces?

The integrated 10/100 Ethernet MAC supports both MII (25-pin) and RMII (9-pin) interfaces, with IEEE 1588v2 hardware timestamping. RMII mode is commonly used to minimize pin count and PCB routing complexity, while MII provides higher flexibility for external PHY selection - both configurations are electrically characterized in DS8597 Section 5.3.28.

Can the USB OTG HS interface operate without an external PHY?

No - the USB OTG HS interface requires an external ULPI-compliant PHY (e.g., SMSC USB334x or Microchip USB3300), connected via PB14–PB15 (ULPI clock/data) and PH12 (ULPI direction). In contrast, the USB OTG FS interface includes an on-chip full-speed PHY and operates standalone - confirmed in DS8597 Section 2.2.30 and Table 59.
