STMicroelectronics STM32F745ZGT7

Overview

STM32F745ZGT7 from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max clock, 1 MB Flash, 320+16+4 KB RAM, USB OTG HS/FS, 10/100 Ethernet MAC, LCD-TFT controller, and dual CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32F745ZGT7 datasheet, STM32F745ZGT7 pinout, STM32F745ZGT7 application, or STM32F745ZGT7 equivalent, key selection criteria include LQFP144 package compatibility, 216 MHz real-time execution with ART Accelerator™ and L1 cache, triple 12-bit ADC (7.2 MSPS interleaved), Chrom-ART Accelerator™ for GUI rendering, and IEEE 1588v2 Ethernet timing support.

Technical Context

The STM32F745ZGT7 implements a dual-bus AXI-AHB matrix architecture enabling concurrent access to Flash, SRAM, and peripherals without contention. Its ART Accelerator™ with 4 KB instruction and 4 KB data caches enables zero-wait-state execution from embedded Flash at 216 MHz.

It integrates dual-mode Quad-SPI, parallel DCMI (54 MB/s), LTDC with XGA resolution support, and two independent SAI audio interfaces with internal audio PLL - all synchronized via a multi-source clock tree including HSE (4–26 MHz), HSI (16 MHz), LSE (32.768 kHz), and programmable PLLs (including PLLSAI for audio/LCD).

The following parts are listed as comparable options for similar high-performance MCU applications.

Compared with STM32F746ZGT6, the STM32F745ZGT7 omits RGB interface support but retains identical Ethernet MAC and CAN features - making it optimal for non-display-centric real-time control. Versus STM32H743ZIT6, it trades peak performance for proven industrial Ethernet integration and lower power at 216 MHz.

FAQ

What is the maximum operating temperature range for STM32F745ZGT7?

The STM32F745ZGT7 is rated for industrial temperature range: –40 °C to +105 °C ambient. This is validated per ST's qualification testing (AEC-Q100 not applicable, but meets IEC 60730 Class B for automatic controls). Thermal derating begins above 85 °C ambient when operating at 216 MHz with full peripheral activation.

Does STM32F745ZGT7 support USB High-Speed device mode without an external ULPI transceiver?

Yes - the STM32F745ZGT7 integrates a dedicated USB 2.0 high-speed PHY with ULPI interface, allowing direct connection to external ULPI transceivers. However, for full-speed-only operation, its on-chip FS PHY suffices. HS device mode requires external ULPI PHY; HS host/OTG modes also require external PHY and dedicated DMA channel.

How many independent clock sources does the STM32F745ZGT7 support simultaneously?

The device supports five concurrent clock sources: HSE (4–26 MHz crystal), HSI (16 MHz RC), LSE (32.768 kHz), LSI (37 kHz RC), and PLL-derived clocks (PLL, PLLSAI, PLLI2S). All can be active simultaneously to feed separate domains - e.g., HSE for Ethernet MAC, LSE for RTC, PLLI2S for audio, and PLL for CPU - with dynamic switching under software control.

Can the STM32F745ZGT7's Ethernet MAC operate in RMII mode with precise IEEE 1588v2 timestamping?

Yes - the integrated 10/100 Ethernet MAC fully supports RMII physical layer interface and provides hardware timestamping for IEEE 1588v2 PTP frames at packet ingress/egress. Timestamp resolution is 20 ns (50 MHz reference), and registers support fine correction of master clock drift - validated in ST reference designs using DP83848 PHY.
