STMicroelectronics STM32F407ZGT7

Overview

STM32F407ZGT7 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating at up to 168 MHz (210 DMIPS), featuring 1 MB flash, 192+4 KB SRAM (including 64 KB CCM), dual CAN 2.0B interfaces, 10/100 Ethernet MAC with IEEE 1588v2 support, and USB OTG HS/FS controllers - deployed in industrial gateways requiring real-time connectivity and deterministic I/O.

For engineers reviewing the STM32F407ZGT7 datasheet, STM32F407ZGT7 pinout, STM32F407ZGT7 application, or STM32F407ZGT7 equivalent, key selection criteria include Ethernet MAC timing compliance, DCMI camera interface bandwidth (up to 54 MB/s), ART Accelerator-enabled zero-wait-state flash execution, and dual-CAN + USB OTG coexistence in resource-constrained embedded designs.

Technical Context

The device integrates an Adaptive Real-Time (ART) Accelerator enabling deterministic 168 MHz execution from flash memory without wait states, paired with a multi-AHB bus matrix for concurrent access to flash, SRAM, and peripherals. Its nested vectored interrupt controller (NVIC) supports up to 240 interrupts with programmable priority levels and low-latency response.

It implements dual clock domains: APB1 (≤42 MHz) for low-speed peripherals (I²C, USART, CAN) and APB2 (≤84 MHz) for high-speed I/O (GPIO, SPI, TIM), while the AHB bus delivers full 168 MHz bandwidth to core-coupled memory (CCM), DMA, and Ethernet MAC - critical for time-sensitive packet processing and real-time control loops.

FAQ

What is the maximum operating temperature rating for STM32F407ZGT7?

The STM32F407ZGT7 is qualified for industrial temperature range: –40°C to +105°C ambient. This rating is verified per JEDEC JESD22-A108 and applies to all LQFP144 variants with ECOPACK2 packaging. Thermal derating begins above 105°C case temperature, and sustained operation beyond this limit risks permanent parametric shift in ADC offset and oscillator stability.

Does STM32F407ZGT7 support hardware encryption acceleration?

No, the STM32F407ZGT7 does not integrate dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries (STM32Cube HAL + mbed TLS) for encryption. For hardware-accelerated crypto, consider STM32L4+, STM32H7, or STM32WB series - the F407's RNG supports entropy seeding but lacks cipher engines.

Can the Ethernet MAC operate in RMII mode with internal clock generation?

Yes, the Ethernet MAC supports RMII mode using the internal 50 MHz clock derived from the PLL (via ETH_CLK output on PA1). External 50 MHz crystal is not required; however, precise 50 MHz timing must be maintained - ST recommends using the internal clock path with proper PCB layout (length-matched traces, ground plane isolation) to meet IEEE 802.3u jitter requirements.

Is the DCMI interface capable of capturing progressive-scan video at 720p resolution?

Yes - with 14-bit parallel DCMI running at 54 MB/s, the STM32F407ZGT7 can capture 1280×720@30 fps (27.6 MB/s raw YUV422) or 1280×720@60 fps (55.3 MB/s) in packed 8-bit mode. Frame rate is constrained by SRAM bandwidth and DMA transfer efficiency; full 720p60 requires double-buffered DMA to avoid line loss during memory write contention.
