STMicroelectronics STM32F415RGT6

Overview

STM32F415RGT6 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 real-time connectivity, secure firmware updates, and multi-protocol fieldbus integration.

For engineers reviewing the STM32F415RGT6 datasheet, STM32F415RGT6 pinout, STM32F415RGT6 application, or STM32F415RGT6 equivalent, key selection criteria include its dual USB OTG capability (HS + FS with dedicated DMA), IEEE 1588v2–enabled Ethernet MAC, triple 12-bit ADCs (7.2 MSPS interleaved), 140 GPIOs (138 5 V-tolerant), and cryptographic hardware acceleration for secure boot and OTA integrity verification.

Technical Context

The STM32F415RGT6 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) supporting deterministic real-time response. Its dual-clock domain architecture separates APB1 (low-speed peripherals) and APB2 (high-speed I/O, timers, ADCs) for precise timing isolation.

It implements a multi-AHB bus matrix connecting CPU, DMA, and peripherals concurrently - critical for simultaneous high-bandwidth operations such as Ethernet packet processing, DCMI camera capture (54 MB/s), and SDIO host transfers without bus contention. The dedicated DMA channels for USB OTG HS, Ethernet, and SDIO ensure deterministic latency for time-critical data pipelines.

FAQ

What is the maximum operating frequency and associated DMIPS rating of the STM32F415RGT6?

The STM32F415RGT6 operates at a maximum CPU frequency of 168 MHz, delivering 210 DMIPS (Dhrystone 2.1) at 1.25 DMIPS/MHz. This performance is sustained with zero-wait-state execution from Flash memory thanks to the integrated Adaptive Real-time Accelerator (ART), making it suitable for real-time control algorithms and signal processing without external memory bottlenecks.

Does the STM32F415RGT6 include hardware cryptographic acceleration, and which algorithms are supported?

Yes, the STM32F415RGT6 integrates dedicated hardware accelerators for AES-128/192/256, Triple DES, HASH (MD5, SHA-1), and HMAC. It also includes a True Random Number Generator (TRNG) compliant with FIPS 140-2 entropy requirements. These features enable efficient TLS 1.2 handshakes, secure boot validation, and encrypted firmware updates without consuming significant CPU cycles.

What package type and pin count does the STM32F415RGT6 use, and what are its thermal characteristics?

The STM32F415RGT6 uses an LQFP64 package (10 × 10 mm, 0.5 mm pitch) with 64 pins and an exposed thermal pad. Its industrial temperature range is –40°C to +85°C. Thermal resistance (θ_JA) is 44.5°C/W, and junction-to-case (θ_JC) is 12.5°C/W - requiring minimum 4×4 mm² copper pour under the thermal pad and ≥4 thermal vias for reliable operation at full clock speed in enclosed enclosures.

Can the STM32F415RGT6 support both USB OTG Full-Speed and High-Speed simultaneously, and what are the physical interface requirements?

No - the STM32F415RGT6 supports USB OTG Full-Speed (via internal PHY on PA11/PA12) and USB OTG High-Speed (via ULPI interface on PB12–PB13 and PB5–PB11), but not simultaneously active on the same port. HS mode requires an external ULPI PHY (e.g., SMSC USB334x), while FS mode uses the on-chip PHY. Designers must select one operational mode per design and route accordingly; dual-role capability is supported, but not concurrent HS+FS traffic.
