STMicroelectronics STM32F437VGT7TR

Overview

STM32F437VGT7TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 180 MHz (225 DMIPS), featuring 1 MB flash, 256 KB SRAM + 4 KB backup SRAM, hardware crypto acceleration (AES-128/192/256, SHA-1/2, HMAC), and integrated 10/100 Ethernet MAC with IEEE 1588v2 support. It targets industrial HMI, networked medical devices, and embedded vision systems requiring real-time processing, secure connectivity, and high-resolution display control.

For engineers reviewing the STM32F437VGT7TR datasheet, STM32F437VGT7TR pinout, STM32F437VGT7TR application, or STM32F437VGT7TR equivalent, key selection criteria include its dual USB OTG (FS/HS), LCD-TFT controller with 83 MHz pixel clock, triple 12-bit ADCs (7.2 MSPS interleaved), 2×CAN 2.0B interfaces, and LQFP100 package with 80 I/Os rated to 90 MHz and 5 V tolerance.

Technical Context

The STM32F437VGT7TR implements an Arm Cortex-M4 core with FPU and Adaptive Real-time Accelerator (ART™) enabling zero-wait-state execution from flash at 180 MHz. Its memory subsystem includes dual-bank flash (1 MB), 256 KB SRAM with 64 KB CCM, and flexible external memory controller supporting SDRAM, NOR, and NAND.

Peripheral integration centers on deterministic real-time I/O: 17 timers (including two 32-bit advanced-control units), 3×12-bit ADCs with 24-channel support and triple interleaving, 8–14-bit parallel camera interface (54 MB/s), and dual USB OTG controllers-one with on-chip FS PHY, the other with dedicated DMA and ULPI for HS operation.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32F437VGT7TR achieves 180 MHz maximum CPU frequency using its internal PLL with HSE (4–26 MHz) or HSI (16 MHz) as source. The Adaptive Real-time Accelerator (ART™) eliminates flash wait states, enabling deterministic zero-latency instruction fetch. Voltage must be ≥2.7 V for full 180 MHz operation per DS9484 Section 6.3.1.

Does this part support external SDRAM, and what interface is used?

Yes, the STM32F437VGT7TR supports external SDRAM via its Flexible Memory Controller (FMC) with 16-bit data bus and programmable timing. It implements standard SDRAM command sequences (ACTIVATE, READ, WRITE, PRECHARGE) and supports densities up to 256 Mbit. Reference design guidelines and timing parameters are specified in DS9484 Section 6.3.26.

How many independent CAN interfaces does it have, and what protocol versions are supported?

The STM32F437VGT7TR integrates two independent bxCAN 2.0B controllers, each supporting both CAN 2.0A (11-bit ID) and CAN 2.0B (29-bit ID) frames, with programmable bit timing, automatic retransmission, and loopback/self-test modes. Both controllers operate concurrently and are electrically isolated from each other at the peripheral level.

Is the LQFP100 package RoHS-compliant and what is its thermal resistance?

Yes, the STM32F437VGT7TR in LQFP100 (14 × 14 mm) is ECOPACK2-compliant (RoHS and halogen-free). Its typical junction-to-ambient thermal resistance (R_θJA) is 44 °C/W under JEDEC JESD51-7 conditions (2s2p board), and junction-to-case (R_θJC) is 12 °C/W - values confirmed in DS9484 Section 7.2 and Table 16.
