STMicroelectronics STM32F756ZGY6TR

Overview

STM32F756ZGY6TR from STMicroelectronics is a high-performance ARM Cortex-M7 microcontroller with FPU, 216 MHz max clock, 1 MB Flash, 320+16+4 KB RAM, hardware crypto acceleration (AES-128/192/256, SHA-1/2, HMAC), and integrated Ethernet MAC + USB OTG HS/FS. It serves as the main application processor in industrial HMI, networked medical devices, and real-time vision systems requiring deterministic execution and multi-interface concurrency.

For engineers reviewing the STM32F756ZGY6TR datasheet, STM32F756ZGY6TR pinout, STM32F756ZGY6TR application, or STM32F756ZGY6TR equivalent, key selection criteria include its dual USB OTG controllers (HS + FS), 10/100 Ethernet MAC with IEEE 1588v2 support, Chrom-ART Accelerator™ for LCD-TFT graphics, and triple-interleaved 12-bit ADC delivering 7.2 MSPS - critical for sensor fusion and closed-loop control.

Technical Context

The device implements a tightly coupled L1 cache (4 KB instruction + 4 KB data) with ART Accelerator™ enabling zero-wait-state execution from Flash or external memory. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to Flash, SRAM, FMC, and peripherals including dual SAI, SPDIFRX, and HDMI-CEC.

Real-time capability is reinforced by dual 32-bit timers (216 MHz), low-power timer (LPTIM1) operational in Stop mode, and dedicated instruction/data TCM RAM (64 KB + 16 KB) for latency-critical routines. The cryptographic engine offloads AES, HASH, and RNG operations without CPU intervention.

FAQ

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

The STM32F756ZGY6TR achieves 216 MHz maximum CPU frequency using its Arm Cortex-M7 core with FPU, supported by the ART Accelerator™ and 4 KB instruction/data L1 cache. This configuration enables zero-wait-state execution from internal Flash or external memory, validated under 1.7–3.6 V supply and ambient temperatures up to 105°C per datasheet DS10915 Rev 5 Section 6.3.1.

Does this MCU support hardware-accelerated cryptography, and which algorithms are implemented?

Yes, it integrates a dedicated cryptographic accelerator supporting AES-128/192/256 encryption/decryption, triple DES, SHA-1/SHA-224/SHA-256 hashing, HMAC generation, true random number generation (TRNG), and CRC calculation - all executed independently of the CPU per Section 3.37 of DS10915 Rev 5.

What Ethernet interface modes does the built-in MAC support?

The integrated 10/100 Ethernet MAC supports both MII and RMII physical layer interfaces, includes hardware IEEE 1588v2 timestamping for sub-microsecond synchronization, and operates with dedicated DMA for zero-copy packet processing - confirmed in Section 3.31 and Table 26 of DS10915 Rev 5.

Is the TFBGA100 package RoHS-compliant and lead-free?

Yes, the STM32F756ZGY6TR in TFBGA100 packaging is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) 3 requirements, as specified in Section 7.3 and Appendix A of DS10915 Rev 5.
