STM32F765BGT6 - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
MPN: STM32F765BGT6 ✗ End of LifeSTM32F765BGT6 Overview
An Arm Cortex-M7 microcontroller is a 32-bit RISC processor within the broader embedded processor and semiconductor hierarchy. Its CPU incorporates a floating-point unit, making it suitable for control algorithms, signal processing, communications, and human-machine-interface workloads. Within STMicroelectronics product families, STM32 devices combine the processor core with memory, clocking, real-time control, security, connectivity, and analog peripherals in one integrated circuit.
The verified product data identifies a maximum operating frequency of 216 MHz, 1 MB of flash organized as 1 M x 8 bits, a 3.3 V supply, and 208 LQFP leads. The large flash capacity supports substantial firmware, bootloader functionality, protocol libraries, and graphical or control logic. The Cortex-M7 floating-point unit supports compact DSP-style calculations without requiring an external processor, while the high clock rate can reduce control-loop latency in demanding embedded systems.
STMicroelectronics groups the STM32F765xx with the STM32F767xx, STM32F768Ax, and STM32F769xx devices in its official documentation. These families share the high-performance Arm Cortex-M7 platform, but firmware selection must account for differences in memory size, peripheral availability, pin assignment, and device-specific hardware features. The family datasheet is the controlling reference for electrical limits, pin multiplexing, boot configuration, clock trees, and peripheral availability.
Typical uses include industrial automation equipment, motor-control systems, networked industrial controllers, high-end audio and communications equipment, test and measurement instruments, and human-machine interfaces. The 208-pin LQFP package provides a large pin count for external memory or communication interfaces, while the 1 MB flash and 512 KB SRAM allow more complex control software to be consolidated onto one device. Exact peripheral assignments must be checked against the selected package variant.
Designers should verify the complete pin and peripheral matrix before layout because an LQFP footprint does not by itself guarantee software or hardware interchangeability. Power, decoupling, clock stability, reset, boot configuration, and unused-pin treatment must follow the manufacturer datasheet. An MCU replacement should be validated for memory requirements, peripheral differences, pin multiplexing, timing, firmware support, and lifecycle status rather than being selected from package dimensions alone.
This page consolidates the verified 216 MHz Cortex-M7 performance, 1 MB flash, 512 KB SRAM, 208-pin LQFP packaging, distributor sourcing, and same-family drop-in assessment into an engineering-focused reference. It also separates confirmed data from fields that still require manufacturer or distributor confirmation, helping designers make a safer sourcing and design decision.

Typical Applications
STM32F765BGT6 is suitable for 6 applications: Industrial Automation Controller, Motor Control System, Industrial Communications Gateway, Test and Measurement Instrument, Human-Machine Interface Controller, Embedded Audio and Signal Processing.
Industrial Automation Controller
The STM32F765BGT6 fits an industrial automation controller because its 216 MHz Cortex-M7 core, 512 KB SRAM, and 1 MB flash can support multitasking control software, communications, and local data buffering. The 208-pin LQFP package offers more external connection options than compact low-pin-count MCUs. In an automated cell, the controller can execute sensor processing, state-machine logic, and communications concurrently while using the floating-point unit for calculations. Firmware and board validation must confirm the required timers, communication ports, analog channels, and alternate-function assignments.
Recommended
Motor Control System
The STM32F765BGT6 is suitable for a sophisticated motor-control system because its 216 MHz Cortex-M7 processing rate can reduce control-loop latency and its floating-point unit supports common transform, filter, and current-control calculations. The 1 MB flash accommodates control firmware, parameter data, and diagnostic routines, while 512 KB of SRAM provides room for sampled data and working buffers. The 208-pin package can expose more timer and communication resources than smaller controllers. Exact PWM channels, encoder interfaces, analog inputs, and timing requirements must be verified against the package pinout before schematic capture.
Recommended
Industrial Communications Gateway
The STM32F765BGT6 can serve as an industrial communications gateway because its 216 MHz Cortex-M7 core, 1 MB flash, and 512 KB SRAM support protocol stacks, buffering, and management firmware in one device. The large 208-pin LQFP package provides additional pins for multiple serial, Ethernet, USB, or fieldbus interfaces when the selected STM32F765 variant exposes them. Engineers should use the package pinout to map transceiver connections, isolation boundaries, and connector functions. The principal benefit is consolidating gateway logic and buffering without moving to a higher-memory MCU, provided all required peripherals are present.
Recommended
Test and Measurement Instrument
The STM32F765BGT6 is appropriate for a high-performance test and measurement instrument because its Cortex-M7 floating-point unit, 216 MHz clock, and large SRAM support sampling, filtering, calibration, and user-interface workloads. The 1 MB flash can hold firmware, lookup data, calibration coefficients, and communications protocols. Its 208-pin package can simplify connections to converters, displays, communications ports, and precision analog circuitry when those functions are available in the exact package variant. Layout must preserve analog and digital return paths while keeping sensitive measurement circuitry away from high-current switching nodes.
Recommended
Human-Machine Interface Controller
The STM32F765BGT6 can support a sophisticated human-machine interface because the 216 MHz Cortex-M7 core handles graphics updates, input handling, and application logic concurrently. Its 512 KB SRAM reduces pressure from display buffers and touch data, while 1 MB flash provides room for interface assets, localization data, and firmware. The 208-pin package offers additional connections for displays, touch controllers, audio, and communications. Because the supplied data does not enumerate package-specific display peripherals, engineers must confirm the peripheral matrix and memory requirements before selecting external components or committing the PCB.
Recommended
Embedded Audio and Signal Processing
The STM32F765BGT6 is suitable for embedded audio and signal-processing systems because the Cortex-M7 floating-point unit supports real-time filtering and signal calculations at up to 216 MHz. The 512 KB of SRAM can hold sample buffers and intermediate results, while the 1 MB flash provides capacity for codecs, control logic, and DSP routines. Its 208-pin package can reduce external component count when suitable audio and communication interfaces are available. Designers should evaluate latency, DMA behavior, peripheral availability, and clock-domain requirements, and should isolate analog audio paths from digital switching noise.

- Large-memory integrated control platform (vs STM32F765BGT8)
Design Notes
Treat the STM32F765BGT6 as a 208-pin LQFP device and use the exact 208-pin land pattern from the manufacturer package drawing. The supplied data confirms a 28 x 28 mm LQFP package but does not include a verified pin table or library SVG. Before PCB release, confirm every supply, ground, decoupling, reset, boot, clock, debug, and alternate-function connection against the datasheet. Incorrect pin numbering in a 208-pin footprint is a significant and difficult-to-debug assembly risk.
Follow the manufacturer's power-supply, decoupling, and voltage-scaling requirements for every operating state. The verified product data identifies a 3.3 V operating supply, but it does not provide the complete regulator topology, current limits, internal-core voltage ranges, or decoupling values. Place required bulk and high-frequency decoupling capacitors at the package pins according to the datasheet, and provide clean sequencing for all supply domains rather than inferring requirements from the 3.3 V label alone.
Preserve the integrity of clocks, debug signals, communications interfaces, and analog measurement paths when planning the 208-pin layout. Route high-current outputs and switching nodes away from sensitive inputs, keep ground returns short, and follow the datasheet guidance for external crystals, load capacitors, and high-speed communication differential pairs. Because the supplied excerpts do not enumerate the complete peripheral matrix, assign pins only after confirming the exact STM32F765BG package variant and alternate-function table.
Do not assume that another STM32 with a similar frequency or flash size is a drop-in replacement. For this part, verify package pin count, power architecture, boot configuration, peripheral availability, DMA mappings, interrupt priorities, firmware device support, and temperature grade. The STM32F765BGT7 and STM32F765BGT8 candidates require ordering-code verification, and STM32F765BG is a family-level designation whose complete commercial suffix must be confirmed before purchase.
Compliance Information
The supplied excerpts do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields must be confirmed on the STMicroelectronics product page or manufacturer compliance documentation.
