STMicroelectronics STM32F407ZGT6J

Overview

STM32F407ZGT6J from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 168 MHz (210 DMIPS), featuring 1 MB flash, 192+4 KB SRAM (including 64 KB CCM), dual CAN 2.0B interfaces, USB OTG HS/FS, and 10/100 Ethernet MAC with IEEE 1588v2 support - deployed in industrial gateways requiring real-time connectivity and deterministic timing.

For engineers reviewing the STM32F407ZGT6J datasheet, STM32F407ZGT6J pinout, STM32F407ZGT6J application, or STM32F407ZGT6J equivalent, key selection criteria include Ethernet MAC + USB OTG HS coexistence, triple 12-bit ADCs (7.2 MSPS interleaved), camera interface (DCMI) bandwidth (54 MB/s), and 140 I/Os with 5 V tolerance for mixed-voltage system interfacing.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 168 MHz, alongside a multi-AHB bus matrix for concurrent peripheral access. Its memory subsystem includes 64 KB core-coupled memory (CCM) for time-critical code/data and 512 bytes of OTP for secure configuration storage.

Peripherals are partitioned across APB1 (low-speed: CAN, I²C, UART) and APB2 (high-speed: GPIO, TIM, ADC) domains, with dedicated DMA channels for Ethernet, USB OTG HS, and DCMI - ensuring deterministic latency for real-time control and streaming applications.

FAQ

What is the maximum operating temperature range for STM32F407ZGT6J?

The STM32F407ZGT6J is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal characteristics in DS8626 Rev 12 specify junction-to-ambient thermal resistance (R_θJA) of 25.5 °C/W for LQFP144, requiring minimum 4-layer PCB with thermal vias under exposed pad for sustained 168 MHz operation at 85 °C.

Does STM32F407ZGT6J support external memory interfaces beyond FSMC?

No - the device implements only the Flexible Static Memory Controller (FSMC) for parallel NOR/NAND/PSRAM/LCD expansion. It does not include Octo-SPI, HyperBus, or LPDDR interfaces. FSMC supports up to 64 MB address space with programmable timing registers for asynchronous/synchronous protocols.

How many independent clock sources does STM32F407ZGT6J provide?

It integrates four clock sources: HSE (4–26 MHz crystal), HSI (16 MHz RC, ±1%), LSE (32.768 kHz crystal for RTC), and LSI (37 kHz RC for watchdog). All can feed PLLs; the main PLL accepts HSE/HSI input and generates system clocks up to 168 MHz, while PLLI2S provides audio-grade clocks for I2S.

Is the Ethernet MAC capable of jumbo frame handling?

Yes - the 10/100 Ethernet MAC supports configurable receive/transmit descriptors and up to 2048-byte frames (jumbo frames) via software configuration of DMA buffer sizes and descriptor ring entries. Hardware checksum offload and scatter-gather DMA are supported, but frame size extension beyond standard 1518 bytes requires application-layer buffer management.
