STM32F765IIK6 - 216MHz Cortex-M7 2MB MCU | STMicroelectronics
The STMicroelectronics STM32F765IIK6 is a 32-bit Arm Cortex-M7 microcontroller with a 216 MHz CPU, 2 MB of flash memory, and a 176+25 UFBGA package measuring 10 mm by 10 mm. It is designed for high-performance embedded control, DSP, graphics, networking, and connected industrial applications. The Cortex-M7 core includes an FPU, DSP instructions, an L1 cache, an MPU, and the ART Accelerator for efficient embedded execution.
An Arm Cortex-M7 microcontroller is a 32-bit embedded processor based on the Arm Cortex-M architecture. It combines real-time interrupt-driven control with higher-performance DSP and floating-point capabilities than typical entry-level microcontrollers. In the STM32 product hierarchy, the STM32F765 belongs to the STM32F7 family of high-performance microcontrollers, combining general-purpose control, memory acceleration, and extensive peripheral integration.
The verified product information identifies a maximum CPU frequency of 216 MHz, 2 MB of flash, a 176+25 UFBGA package, and a 10 mm by 10 mm package size. The manufacturer’s STM32F765 product family datasheet also identifies up to 2 MB flash, 462 DMIPS, SDRAM, DFSDM, and advanced signal-processing and connectivity features. These characteristics make the STM32F765IIK6 suitable for applications requiring more computation and memory than a basic Cortex-M microcontroller.
The Cortex-M7 architecture is designed to improve instruction throughput through its pipeline, cache mechanisms, DSP support, and ART Accelerator. The FPU supports floating-point workloads, while DSP instructions accelerate common filtering and signal-processing operations. An MPU can provide memory-protection capabilities for systems that require isolation between critical tasks or software components. These features are especially valuable in control systems, audio equipment, industrial controllers, and embedded human-machine interfaces.
Typical applications include industrial automation, motor and motion control, audio and DSP systems, communications equipment, test and measurement instruments, and connected embedded products. The STM32F765IIK6 is also identified by a distributor source as a supported flight-controller MCU target in the STM32F7X5 family. For flight-control designs, careful validation of motor control, sensor timing, power supplies, and firmware remains essential.
The 176+25 UFBGA package is a fine-pitch, high-density package that requires careful PCB layout, controlled escape routing, adequate power delivery, and reliable assembly capability. The 10 mm by 10 mm outline and 0.65 mm pitch place demands on via planning, solder mask, thermal management, and inspection. The package is not a direct substitute for parts using a leaded package or a different ball count.
This page consolidates verified distributor information, the manufacturer datasheet link, application context, comparison fields, and practical design considerations. Because the supplied web results do not expose a complete verified price table or a complete manufacturer pinout list, unavailable values are marked for validation rather than inferred.
The STM32F765IIK6 should be selected when a design specifically requires the STM32F765 device identity, 216 MHz Cortex-M7 performance, 2 MB flash, and the 176+25 UFBGA footprint. Confirm package pin assignments, voltage rails, memory configuration, peripheral availability, lifecycle status, and assembly capability against the official STM32F765 family datasheet before releasing a production PCB.
