Product details

Overview

STM32F415VGT6TR 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), dual CAN 2.0B interfaces, and integrated 10/100 Ethernet MAC with IEEE 1588v2 support - deployed in industrial gateways requiring secure, real-time connectivity and deterministic timing.

For engineers reviewing the STM32F415VGT6TR datasheet, STM32F415VGT6TR pinout, STM32F415VGT6TR application, or STM32F415VGT6TR equivalent, key selection criteria include its dual USB OTG capability (FS + HS with dedicated DMA), parallel camera interface (DCMI, up to 54 MB/s), triple 12-bit ADCs (7.2 MSPS interleaved), and 140 GPIOs with 5 V tolerance - critical for high-bandwidth sensor fusion and protocol bridging designs.

Technical Context

The STM32F415VGT6TR integrates an Adaptive Real-Time (ART) Accelerator 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 task scheduling. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripherals without contention.

It implements two independent USB controllers: OTG_FS with on-chip PHY and OTG_HS with ULPI interface and dedicated DMA, plus a full-duplex 10/100 Ethernet MAC supporting MII/RMII and hardware timestamping per IEEE 1588v2 - enabling simultaneous high-speed device/host operation and precision time-synchronized networking.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	Arm Cortex-M4 with FPU, 168 MHz max, 210 DMIPS - enables floating-point-intensive control algorithms (e.g., motor FOC, FFT-based signal analysis) without external coprocessor.
Memory	1 MB Flash + 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM - CCM supports low-latency data buffers for time-critical ISR handling; backup SRAM retains state during Stop/Standby modes.
Crypto Engine	AES-128/192/256, Triple DES, SHA-1, MD5, HMAC - accelerates TLS handshake and firmware signature verification in edge node security stacks.
ADC/DAC	3×12-bit ADCs (2.4 MSPS each, 7.2 MSPS triple interleaved) + 2×12-bit DACs - supports simultaneous multi-channel analog acquisition (e.g., 3-phase current/voltage sensing) with sub-microsecond sampling alignment.
Connectivity	Dual CAN 2.0B, USB OTG FS/HS, 10/100 Ethernet MAC, SDIO, DCMI (54 MB/s), 15 comm. interfaces - enables protocol gateway functionality (e.g., CAN-to-Ethernet bridging with packet timestamping).
Timers	Up to 17 timers including 12×16-bit and 2×32-bit units, each with 4x IC/OC/PWM channels and quadrature encoder input - supports complex motion control with synchronized PWM generation and position capture.
I/O	140 GPIOs, 136 fast I/Os (84 MHz), 138 5 V-tolerant pins - allows direct interfacing with legacy 5 V logic, industrial sensors, and display drivers without level shifters.

Pinout & Package

LQFP100 (14 × 14 mm) package with exposed thermal pad; 100-pin quad flat pack suitable for industrial PCB assembly and thermal management via bottom-side copper pour.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VDDA, VCAP_1/2	Power supply inputs	VDD (1.8–3.6 V) powers digital core; VDDA (1.8–3.6 V) supplies analog domain; VCAP_1/2 stabilize internal regulator - requires 2.2 µF ceramic capacitors per VCAP pin for stable 1.2 V core voltage.
PA0–PA15, PB0–PB15, etc.	General-purpose I/O banks	140 total GPIOs grouped into ports A–K; most support multiple alternate functions (e.g., USART2_TX on PA2, TIM5_CH1 on PA0) - enables flexible peripheral mapping and pin conflict resolution.
PA11/PA12, PB14/PB15	USB OTG FS/HS physical layer	PA11/PA12 = OTG_FS_DM/DP; PB14/PB15 = OTG_HS_ULPI_D0/D1 - HS mode requires external ULPI transceiver; FS mode uses integrated PHY for plug-and-play device enumeration.
PH13–PH15, PI0–PI10	DCMI parallel camera interface	8-bit/10-bit/12-bit data bus (D0–D11), HSYNC/VSYNC/PCLK - supports CMOS image sensors up to UXGA (1600×1200) at 15 fps with hardware frame synchronization.
PC1–PC4, PD8–PD15	Ethernet MAC interface	MII/RMII signals (TXD0–TXD3, RXD0–RXD3, TX_EN, CRS_DV, REF_CLK) - RMII reduces pin count to 9 signals; MII enables full 10/100 operation with external PHY.

Key Features

Feature	Design Value
ART Accelerator	Enables zero-wait-state Flash execution at 168 MHz - eliminates instruction fetch stalls, ensuring deterministic ISR latency (<1 µs) for hard real-time control loops.
CCM RAM	64 KB tightly coupled memory accessible only by CPU - stores critical stack, control variables, and filter coefficients to avoid cache misses during high-priority interrupts.
Hardware RNG	True random number generator compliant with NIST SP800-90B - provides entropy source for cryptographic key generation without software bias or timing side channels.
IEEE 1588v2 Support	Hardware timestamping engine in Ethernet MAC - achieves sub-100 ns packet timestamp accuracy for time-sensitive networking (TSN) applications like synchronized PLC I/O.
Flexible Static Memory Controller (FSMC)	Supports NOR, PSRAM, NAND, and CompactFlash with programmable timing - enables direct attachment of external displays, FPGA co-processors, or legacy memory-mapped peripherals.

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	Includes Ethernet PHY (internal 10/100 PHY vs. MAC-only in F415); adds LCD-TFT controller and Chrom-ART accelerator.	Targeted at HMI-centric designs with embedded display; lacks DCMI interface and has reduced GPIO count (114 vs. 140).	Select F417 when integrated display driving is required and camera interface is unnecessary.
STM32H743VIT6	Dual-core (Cortex-M7 @ 480 MHz + Cortex-M4 @ 240 MHz); 2 MB Flash, 1 MB RAM; no hardware crypto for SHA/MD5 but adds PKA (public key accelerator).	Designed for asymmetric workloads (e.g., M7 handles AI inference, M4 manages real-time I/O); higher power and cost, incompatible pinout.	Choose H743 only when >2× performance uplift justifies redesign, BOM increase, and thermal redesign.

Compared with STM32F417VGT6, the STM32F415VGT6TR offers superior camera interface bandwidth and GPIO count but requires external Ethernet PHY; versus STM32H743VIT6, it delivers proven industrial reliability at lower cost and power, with full pin compatibility across LQFP100 F4-series variants.

FAQ

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

The STM32F415VGT6TR operates at up to 168 MHz using its internal PLL driven by either the 4–26 MHz HSE crystal oscillator or the 16 MHz HSI RC oscillator. The Adaptive Real-Time (ART) Accelerator enables zero-wait-state execution from Flash memory at this frequency, verified per DS8597 Rev 9 Section 2.2.2. This eliminates instruction fetch bottlenecks, ensuring consistent cycle-per-instruction timing for hard real-time tasks.

Does this MCU support hardware encryption for TLS/SSL offloading?

Yes - the STM32F415VGT6TR integrates dedicated hardware accelerators for AES-128/192/256, Triple DES, SHA-1, MD5, and HMAC. These engines operate independently of the CPU core and are accessible via DMA, enabling full TLS 1.2 record encryption/decryption at line rate without degrading application throughput. Performance data is specified in DS8597 Section 2.2.33 and Table 39.

What are the key differences between OTG_FS and OTG_HS interfaces?

OTG_FS uses an integrated full-speed PHY and supports device/host/OTG roles with minimal external components; OTG_HS requires an external ULPI transceiver and supports high-speed (480 Mbps) operation with dedicated DMA channel. Both are electrically and logically independent - allowing concurrent USB device (e.g., CDC ACM) and host (e.g., mass storage) operation, as confirmed in DS8597 Sections 2.2.30 and 2.2.31.

Can the Ethernet MAC operate without an external PHY?

No - the STM32F415VGT6TR implements only the Media Access Control (MAC) layer, not the Physical Layer (PHY). It supports both MII (16-signal) and RMII (9-signal) interfaces to external 10/100 PHYs such as the LAN8720A or DP83848. IEEE 1588v2 timestamping is performed in the MAC, but signal-level encoding/decoding and cable driving require an external PHY, per DS8597 Section 2.2.28.
