Product details
Overview
STM32F415ZGT6 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 deterministic I/O control.
For engineers reviewing the STM32F415ZGT6 datasheet, STM32F415ZGT6 pinout, STM32F415ZGT6 application, or STM32F415ZGT6 equivalent, key selection criteria include its LQFP144 package with 138 5 V-tolerant I/Os, triple 12-bit ADCs (7.2 MSPS interleaved), parallel camera interface (54 MB/s), and dedicated DMA for Ethernet/USB HS - critical for embedded vision, protocol bridging, and secure edge node design.
Technical Context
The STM32F415ZGT6 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 peripheral access without contention.
It implements dual USB controllers: full-speed OTG with on-chip PHY and high-speed OTG with ULPI interface and dedicated DMA; plus IEEE 1588v2-compliant Ethernet MAC with MII/RMII support and hardware timestamping - enabling time-synchronized industrial communication stacks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4 with FPU, 168 MHz max, 210 DMIPS - enables floating-point-intensive motor control or sensor fusion without external coprocessor. |
| Memory | 1 MB Flash + 192 KB SRAM + 4 KB backup SRAM + 64 KB CCM - supports large RTOS images, dual-bank firmware updates, and low-latency data buffering. |
| Crypto Engine | AES-128/192/256, Triple DES, SHA-1, MD5, HMAC - accelerates TLS handshake, secure boot verification, and OTA update signature validation in <5 ms. |
| ADC/DAC | 3×12-bit ADCs (2.4 MSPS each, 7.2 MSPS interleaved), 2×12-bit DACs - meets requirements for multi-channel analog acquisition (e.g., power quality monitoring) and waveform generation. |
| Connectivity | 2×CAN 2.0B, USB 2.0 FS/HS OTG, 10/100 Ethernet MAC, SDIO, DCMI (54 MB/s) - enables protocol gateway functionality (CAN-to-Ethernet bridging) and embedded vision preprocessing. |

Pinout & Package
LQFP144 (20 × 20 mm) package with exposed thermal pad; 144-pin quad flat pack offering mechanical robustness and reflow-compatible assembly for industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD/VSS | Core & I/O supply rails | Dual 1.8–3.6 V domains: VDD powers core/peripherals; VSS provides reference return - requires separate decoupling per voltage domain. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O banks | 140 total GPIOs grouped into A–K ports; most support 5 V tolerance and multiple alternate functions (e.g., TIMx_CHy, USARTx_TX). |

| PC10/PC11 | ETH_MDC/ETH_MDIO | Management Data Input/Output for Ethernet PHY configuration - required for auto-negotiation and link status polling in IEEE 802.3 networks. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator | Zero-wait-state Flash execution at 168 MHz - eliminates instruction cache misses in deterministic control loops (e.g., servo position tracking). |
| Flexible Static Memory Controller (FSMC) | Supports NOR/NAND/PSRAM/CompactFlash - enables direct attachment of external display buffers or legacy industrial memory modules without glue logic. |
| Dedicated Ethernet DMA | Separate 8-channel DMA engine for MAC - prevents CPU starvation during sustained 100 Mbps packet throughput; supports scatter-gather descriptors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F417ZGT6 | Adds Ethernet PHY interface (MII only, no RMII); identical Flash/SRAM/crypto/peripherals. | Requires external PHY for MII; lacks internal full-speed USB PHY (uses external ULPI for FS). | Select when MII-based Ethernet is mandatory and external PHY integration is acceptable. |
| STM32F746ZGT6 | Higher clock (216 MHz), larger Flash (1 MB), added Chrom-ART accelerator, FMC instead of FSMC, no DCMI. | Better graphics performance but loses camera interface; USB HS/FS retained, Ethernet MAC unchanged. | Select for GUI-rich HMI applications where camera input is unnecessary and higher CPU throughput is prioritized. |
Compared with STM32F417ZGT6, the STM32F415ZGT6 offers integrated USB FS PHY and RMII support - reducing component count in compact gateways. Versus STM32F746ZGT6, it retains DCMI and FSMC for legacy memory/display compatibility at lower cost and power, making it optimal for vision-enabled industrial edge nodes.

FAQ
What is the maximum operating temperature range for STM32F415ZGT6?
The STM32F415ZGT6 is rated for industrial temperature range: –40 °C to +85 °C ambient, validated per JEDEC JESD22-A104. Thermal derating begins above 70 °C ambient when operating at 168 MHz with all peripherals active; full specification compliance is guaranteed within this range.
Does STM32F415ZGT6 support TrustZone or other hardware-based secure isolation?
No. The STM32F415ZGT6 does not include Arm TrustZone technology. It relies on its Memory Protection Unit (MPU) and hardware crypto accelerators (AES, HASH, RNG) for software-enforced security boundaries and cryptographic operations - sufficient for IEC 62443-3-3 SL1 but not SL2+ without additional secure element integration.
Can the internal 16 MHz RC oscillator be used as system clock source for USB operation?
No. USB Full-Speed requires a clock with ≤±0.25% accuracy; the internal 16 MHz RC oscillator has ±1% factory trim accuracy and drifts with voltage/temperature. USB FS must use HSE (4–26 MHz crystal) or PLL-derived clock locked to HSE - confirmed in Section 5.3.9 of DS8597 Rev 9.
How many independent CAN FD controllers does STM32F415ZGT6 support?
Zero. The STM32F415ZGT6 integrates two bxCAN 2.0B controllers only - supporting Classical CAN (up to 1 Mbps) but not CAN FD (Flexible Data-Rate). CAN FD capability was introduced in later families (e.g., STM32H7, STM32G4) and is explicitly absent in the F415/F417 documentation.
