An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, and a rich set of peripherals such as timers, ADCs, and communication interfaces. The STM32F7 family sits at the high-performance end of the Cortex-M hierarchy — Cortex-M7 > Cortex-M4 > Cortex-M3 > Cortex-M0 — and is a member of the broader Arm Cortex-M MCU taxonomy under embedded microcontrollers, semiconductor devices, and integrated circuits. Within ST's portfolio, the F7 line bridges Cortex-M4-class parts (such as the STM32F4 series) and Cortex-M7 application processors.
Key features include up to 17 timers (including motor-control, HRTIM, and 32-bit timers), two 12-bit ADCs sampling at 2.4 MSPS, two 12-bit DACs, a true random number generator (RNG), cryptographic accelerators, and a Chrom-ART accelerator for offloading GUI rendering. An integrated 2.4-inch TFT-LCD controller (LTDC) supports up to XGA resolution without an external graphics chip, while USB 2.0 High-Speed with on-chip PHY and 10/100 Ethernet with IEEE 1588 make the part attractive for connected embedded designs.
Architecturally, the Cortex-M7 core pairs a 6-stage superscalar pipeline with branch prediction and tightly-coupled memory for deterministic interrupt response. The 2 MB of dual-bank Flash supports read-while-write for safe in-field firmware upgrades, and the 512 KB SRAM is split into multiple AHB-matrix regions for simultaneous DMA and CPU access. This bandwidth is what allows driving parallel TFT displays while running DSP-style audio or motor-control loops concurrently.
Typical applications include industrial HMI panels with TFT-LCD touchscreens, motor-control and field-oriented control drives, industrial Ethernet gateways, USB audio interfaces, and barcode/scanner modules. Specific uses range from PLC operator panels to medical instrumentation front-ends and office printers requiring raster image processing. When PCB area is constrained, designers often migrate to the LQFP-100 or LQFP-176 versions of the same silicon, but the ZIT6 in LQFP-144 maximizes peripheral exposure without stepping up to a BGA.
For power-supply design, the part requires a 1.8V to 3.6V supply with decoupling on every VDD/VBAT pin; bypassing must keep PCB track inductance below roughly 1 nH to avoid noise coupling into the PLL. Trade-off: peak performance at 216 MHz pushes core current beyond 100 mA, so efficiency-aware designs often drop to 180 MHz when full throughput is not required. This page synthesizes distributor pricing, same-package drop-in alternatives from across the STM32 family, and design notes not contained in a single manufacturer datasheet.

典型應用
STM32F765ZIT6 適用於 6 應用s: Industrial HMI with TFT-LCD, USB Audio Interface, Motor Control and Field-Oriented Control (FOC), Industrial Ethernet Gateway, Medical Instrumentation, High-Speed Data Logger and Image Processing.
Industrial HMI with TFT-LCD
The STM32F765ZIT6 drives industrial HMI panels through its integrated LTDC controller at up to XGA resolution, paired with the Chrom-ART accelerator that offloads GUI composition from the Cortex-M7 CPU. Its 216 MHz speed and 2 MB Flash let designers store multilingual UI assets and vector fonts on-chip, while the 512 KB SRAM buffers framebuffers without external RAM. The on-chip 10/100 Ethernet MAC and USB HS OTG simplify wiring to PLCs and remote IO, and the LQFP-144 keeps the PCB within easy hand-rework tolerance for industrial control panel assemblies.
推薦
USB Audio Interface
The STM32F765ZIT6's USB 2.0 High-Speed OTG controller with on-chip PHY allows USB audio designers to implement UAC 2.0 multi-channel interfaces without external high-speed PHY chips. Its Cortex-M7 DSP extensions and double-precision FPU handle real-time audio mixing and effects at 216 MHz while consuming a few tens of mA. The peripheral set, including I2S, S/PDIF, and 12-bit DACs, supports both line and headphone out, and 2 MB Flash holds firmware, factory presets, and DSP tables on-chip for turnkey consumer audio products.
推薦
Motor Control and Field-Oriented Control (FOC)
Field-oriented control of 3-phase PMSM or induction motors benefits from the STM32F765ZIT6's HRTIM (high-resolution timer) and the 217 MHz Cortex-M7 with single-precision FPU executing park/clarke transforms at each PWM cycle. The 2 MB Flash stores sensorless observer tables and motor parameter libraries, while 512 KB SRAM keeps fast current/torque control loops in tight CPU cycles. The LTDC peripheral is dormant in pure motor designs, but the rich timer, ADC (2.4 MSPS), and comparator blocks make this part unusually capable for combined motor+BLDC/HMI applications.
推薦
Industrial Ethernet Gateway
For industrial Ethernet gateways the STM32F765ZIT6 brings a hard 10/100 MAC plus IEEE 1588 precision-time support, paired with Cortex-M7 throughput sufficient for protocol parsing of Profinet, EtherNet/IP, or Modbus-TCP at wire speed. Its dual-bank 2 MB Flash allows safe in-field firmware updates across long equipment lifecycles, and the package's 144 pins provide multiple UART/SPI/CAN paths to bridge between PLC networks and external sensors. The MCU also includes a true random number generator used for TLS handshake entropy in secured remote-management scenarios.
推薦
Medical Instrumentation
Patient-monitoring and diagnostic-instrument front-ends value the STM32F765ZIT6's combination of 12-bit ADCs at 2.4 MSPS, 32-bit timers for precise event scheduling, and a Cortex-M7 that runs DSP-style filter chains (IIR/FIR for ECG) within the I-cache/D-cache at 216 MHz. The 2 MB Flash enables storing configuration profiles for each supported sensor lead on-chip. Tightly-coupled memory and 512 KB SRAM let the firmware execute deterministic ISR loops required for IEC 60601-compatible medical designs, while the LQFP-144 simplifies prototyping and rework in R&D labs.
推薦
High-Speed Data Logger and Image Processing
Industrial imagers and data loggers exploit the STM32F765ZIT6's 16-Kbyte data cache to process image or sensor buffers without stalling the Cortex-M7 pipeline, while the Chrom-ART engine handles 2D graphics copy/format conversion in hardware. SDMMC peripherals, USB HS, and 10/100 Ethernet move bulk data off the device, and 2 MB Flash lets designers include multiple compressed code modules for hardware-as-a-service deployments. Designers typically pair the part with SDRAM for framebuffer expansion when LTDC + camera-DVP pipelines are simultaneously active.

主要差異化特點
- Highest-density dual-bank Flash in the F765 family for this package (對比STM32F765ZGT6)
- Most affordable Cortex-M7 dual-bank Flash on LQFP-144 (對比STM32F746ZET6)
- On-chip LTDC + USB HS without external PHY (對比STM32F427IIT6)
設計說明
Estimated: at 216 MHz full CPU load the core current can exceed 100 mA from VDD (1.8 V to 3.6 V). Place a 100 nF + 4.7 µF ceramic decoupling stack on each VDD/VDDA/VBAT pin. Keep the bypass loop area under approximately 1 nH per pin by using short, wide vias; for multi-rail designs add a ferrite bead feeding VDDA from VDD to reduce switching-coupled noise.
Estimated: route USB 2.0 High-Speed differential pairs (D+/D-) on the top layer with 90-ohm differential impedance and length matching under 0.5 mm. Place the 27 k + 22 ohm external pull/pulldown for the HS PHY adjacent to the MCU. Use an LQFP-144 footprint with 0.5 mm pitch and at least 4 inner vias under the exposed pad for thermal relief.
Confirmed datasheet requirement: configure BOOT0 via external 100 k pulldown to GND during normal operation; otherwise the part may boot into bootloader mode. Estimated: do not enable both USB HS PHY and external 50 ohm termination simultaneously - register OTG_FS.GCCFG must match your hardware. For 1.8 V operation, ensure PWR_REGULATOR selects Voltage Range 2 and that VOS bit is configured for performance before raising SYSCLK above 168 MHz.
