STM32F765ZIT7 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable I/O peripherals. The Cortex-M7 is ARM's highest-performance Cortex-M core, featuring a six-stage superscalar pipeline, branch prediction, and an integrated single-precision floating-point unit; it sits at the top of the Cortex-M family alongside the Cortex-M4 and Cortex-M33. STM32F7-series MCUs belong to the broader ARM Cortex-M taxonomy, which itself falls under 32-bit RISC microcontrollers and, more generally, embedded microprocessors and semiconductor ICs. Compared with Cortex-M4 parts, the Cortex-M7 offers roughly doubled DSP performance and is aimed at demanding signal-processing and graphics workloads.
Key features that distinguish this part include the dual-bank 2 MB Flash with ART Accelerator for zero-wait-state execution from Flash, 16-bit and 32-bit timers, up to 28 communication interfaces (USART/UART/SPI/I2S/I2C), a 12-bit ADC reaching 2.4 MSPS, two 12-bit DACs, an SDMMC host interface for external SD cards or eMMC, and an Ethernet MAC with dedicated DMA. The integrated cryptographic accelerator (AES-256, SHA-1/SHA-2, HMAC, and TRNG) enables hardware-bound secure boot and TLS/SSL offload. The Chrom-ART Accelerator 2D DMA engine accelerates bitmap operations for HMI applications.
Typical applications include industrial motor drives and PLCs, medical patient-monitoring and diagnostic equipment, human-machine interface (HMI) panels with TFT-LCD or DSI displays, factory-automation controllers with EtherCAT/PROFINET bridges, point-of-sale terminals, building-automation gateways, and audio-processing units including USB audio class endpoints. The 216 MHz Cortex-M7 with single-precision FPU and DSP extensions makes the part particularly suited to real-time FFT-based analytics, digital filtering, and motor-control algorithms using FOC (field-oriented control). Pin-compatible upgrades within the STM32F765 family extend to the STM32F767/F769 line for projects that need additional MIPI-DSI lanes or the SPDIF interface.
When designing with this MCU, attention must be paid to decoupling (1 uF + 100 nF near each VDD pin), the layout of the 25 MHz HSE crystal traces within 5 mm of the OSC_IN/OSC_OUT pins, and the thermal dissipation in continuous high-CPU-load scenarios. The 144-LQFP package has a thermal resistance of approximately 38 C/W (theta_JA on a 4-layer JEDEC board) and is adequate for industrial operating points up to about 0.8 W steady-state dissipation without airflow.

設計ノート
The STM32F765ZIT7 requires a clean 3.3 V supply with adequate decoupling: place one 100 nF X7R ceramic capacitor within 2 mm of each VDD/VDDA pin, plus a bulk 4.7 uF tantalum at the regulator output. The VDDA (analog supply) should be filtered through a ferrite bead from VDD and decoupled with a 10 nF + 1 uF pair. Power-on reset behavior depends on VDD rising monotonically within 10 ms; if using a soft-start regulator, ensure the ramp time is within the datasheet limits.
Route the HSE crystal traces (25 MHz typical) within 5 mm of the OSC_IN/OSC_OUT pins, keeping both traces symmetric in length and shielded by a ground guard trace. Keep high-frequency switching signals (SDRAM, DSI, USB) away from the HSE traces to avoid noise injection. For the 144-LQFP, place the exposed thermal pad (if present) to a continuous ground plane with thermal vias (0.3 mm pitch) to dissipate the 0.5-0.8 W steady-state load. Estimated: at 216 MHz with all peripherals enabled, core dissipation is approximately 0.5 W.
Estimated: at 216 MHz CPU and 3.3 V supply, the STM32F765ZIT7 dissipates approximately 0.5 W in continuous active mode. With a 144-LQFP theta_JA of about 38 C/W on a 4-layer JEDEC board (per datasheet), this yields a 19 C junction temperature rise above ambient, well within the 85 C industrial limit. However, running industrial-grade parts at the upper temperature extreme (85 C ambient) leaves only 0 C margin; plan for 70 C ambient maximum in sealed enclosures without airflow.
Do not enable the ART Accelerator with the Flash prefetch queue disabled - the M7's zero-wait-state promise depends on both. When migrating from F407 code, the I2S peripheral registers moved between revisions; check the migration notes in the F7 reference manual RM0410. The USB OTG HS PHY requires a 24 MHz reference clock from the HSE crystal; external clock sources without proper PLL configuration will fail USB certification.
