Product details
Overview
STM32F415VGT7 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 STM32F415VGT7 datasheet, STM32F415VGT7 pinout, STM32F415VGT7 application, or STM32F415VGT7 equivalent, key selection criteria include its dual USB OTG capability (FS + HS with dedicated DMA), parallel camera interface (DCMI) supporting up to 54 MB/s, triple 12-bit ADCs (7.2 MSPS interleaved), and 140 GPIOs with 5 V tolerance - critical for embedded vision, protocol bridging, and multi-interface edge nodes.
Technical Context
The STM32F415VGT7 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 task scheduling. Its multi-AHB bus matrix concurrently services CPU, DMA, and peripherals without contention.
It features dual USB controllers (OTG_FS with on-chip PHY and OTG_HS with ULPI interface and dedicated DMA), a full-duplex 10/100 Ethernet MAC with hardware timestamping, and a dedicated flexible static memory controller (FSMC) supporting NOR/NAND/PSRAM - enabling simultaneous high-bandwidth external memory access and networked I/O.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU, 168 MHz max frequency, 210 DMIPS performance - enables floating-point-intensive control algorithms without software emulation. |
| Memory | 1 MB Flash (0-wait-state via ART Accelerator), 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM - supports large firmware images, real-time data buffers, and low-latency core-coupled variables. |
| Crypto Engine | Hardware AES-128/192/256, Triple DES, SHA-1, MD5, HMAC - accelerates TLS handshake, secure boot, and firmware signature verification in under 10 µs per block. |
| Connectivity | Dual CAN 2.0B, USB OTG FS + HS (with ULPI), 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping - enables time-synchronized industrial networking and protocol gatewaying. |
| Analog Peripherals | Three 12-bit ADCs (2.4 MSPS each, 7.2 MSPS triple interleaved), two 12-bit DACs - supports high-speed motor current sensing and precision analog output generation. |
| Timing & Clock | 4–26 MHz crystal oscillator input, 32 kHz RTC oscillator with calibration, internal 16 MHz RC (±1%) - ensures accurate timekeeping and robust clock source redundancy. |
| I/O Capability | 140 GPIOs, 138 of which are 5 V-tolerant, up to 84 MHz toggle rate - allows direct interfacing with legacy 5 V logic and high-speed digital signaling without level shifters. |
Pinout & Package
LQFP100 (14 × 14 mm) package with 100-pin quad flat pack, thermally enhanced for industrial ambient operation up to 105°C junction temperature. Pinout validated per STMicroelectronics DS8597 Rev 9, Section 3 "Pinouts and pin description".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | 1.8–3.6 V main supply; separate VCAP pins require 2.2 µF ceramic capacitors for core regulator stability. |

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, memory, and peripherals, but includes Ethernet PHY interface (MII/RMII + PHY) - adds 25 mW static power and requires additional PHY layout area. | Eliminates need for external Ethernet PHY; suitable when board space permits integrated PHY and lower EMI is required. | Select if Ethernet PHY integration reduces system cost and layout complexity; avoid if thermal budget is constrained or external PHY offers better noise immunity. |
| STM32H743VIT6 | Arm Cortex-M7 @ 480 MHz, dual-core option, 2 MB Flash, no hardware crypto for SHA/MD5 - adds DCache/ICache, AXI bus, and higher DMIPS but lacks native MD5/HMAC acceleration. | Targeted at compute-heavy applications (e.g., AI inference, video encoding); not drop-in compatible due to different register map and peripheral addressing. | Choose for >2× CPU performance and advanced memory subsystem; retain STM32F415VGT7 when crypto offload (SHA-1, HMAC) and IEEE 1588v2 timestamping are mandatory. |
Compared with STM32F417VGT6, the STM32F415VGT7 trades integrated Ethernet PHY for lower power and smaller footprint; versus STM32H743VIT6, it retains hardware MD5/HMAC and IEEE 1588v2 support at lower clock speed - making it optimal for deterministic, crypto-anchored industrial networking where real-time latency and protocol compliance outweigh raw compute throughput.

FAQ
What is the maximum operating temperature and voltage range for STM32F415VGT7?
The STM32F415VGT7 operates from −40°C to +105°C ambient temperature with a supply voltage range of 1.8 V to 3.6 V. Its VCAP pins require 2.2 µF ceramic capacitors for stable core regulator operation, and all 138 GPIOs are 5 V-tolerant - enabling robust interfacing with mixed-voltage systems without external level-shifting circuitry.
Does STM32F415VGT7 support USB High-Speed (480 Mbps) natively?
No - the STM32F415VGT7 includes a USB OTG High-Speed controller that requires an external ULPI PHY (e.g., SMSC USB334x) to achieve 480 Mbps operation. It integrates a full-speed USB OTG controller with on-chip PHY for 12 Mbps operation, but high-speed mode mandates external PHY connectivity via the ULPI interface (PH13–PH20).
How many independent ADCs does STM32F415VGT7 have, and what is their combined sampling rate?
The STM32F415VGT7 integrates three independent 12-bit ADCs, each capable of 2.4 MSPS. In triple interleaved mode, they achieve a combined sampling rate of 7.2 MSPS across up to 24 channels - enabling simultaneous high-fidelity acquisition of motor phase currents, temperature, and auxiliary analog signals in real-time control loops.
Is the STM32F415VGT7 pin-compatible with other STM32F4xx variants in LQFP100?
Yes - the STM32F415VGT7 shares identical pinout and electrical characteristics with other STM32F415xx and STM32F417xx devices in the LQFP100 package (e.g., STM32F417VGT6), per ST's full compatibility guarantee in DS8597 Section 2.1. This allows hardware reuse across variants differing only in Flash size, crypto features, or Ethernet PHY integration.
