STM32F767IGK6 - 216MHz Cortex-M7 MCU 1MB Flash 176+25UFBGA
MPN: STM32F767IGK6 ✓ Hoạt độngSTM32F767IGK6 Tóm tắt
An ARM Cortex-M7 microcontroller belongs to the ARM Cortex-M processor family, designed for embedded real-time systems. The Cortex-M7 is the highest-performance member of this family, featuring a superscalar pipeline, branch prediction, single-precision and double-precision FPU, and dedicated DSP extensions (SIMD). These MCUs sit in the embedded processor hierarchy: microcontroller -> embedded processor -> semiconductor IC, and are used wherever deterministic real-time response, rich connectivity, and graphics/audio processing are required in a single chip.
Key features include an integrated 216 MHz Cortex-M7 core with 16 KB I-cache and 16 KB D-cache for high-throughput execution, hardware JPEG codec, random number generator (TRNG), and crypto/hash peripherals supporting AES-256, SHA-256, and HMAC. Three 12-bit ADCs sample at 2.4 MSPS each, and the device also includes two 12-bit DACs, up to 18 timers, and an SDMMC interface for microSD card storage. The LQFP176/UFBGA176 family pinout supports display interfaces (LCD-TFT) and an 8- to 14-bit camera parallel interface.
The architecture combines an AXI/AHB multilayer bus matrix with a dedicated Chrom-ART graphics accelerator, enabling efficient on-chip LTDC and DMA2D operations without burdening the CPU. This makes the STM32F767IGK6 suitable for human-machine interfaces (HMI), where the CPU remains free for application logic while the accelerator handles pixel rendering.
Typical applications include industrial HMI panels with TFT LCD touchscreens, motor-control inverter boards, building-automation gateways with Ethernet connectivity, point-of-sale and barcode-scanner terminals, medical patient-monitoring front panels, and consumer audio products that need MP3/WMA decoding with on-the-fly graphics overlays.
When designing with this part, ensure that the PCB's thermal copper pour covers the exposed pad of the UFBGA to meet the 216 MHz current demand; an inadequate thermal land will push the junction temperature above the 125 C limit during heavy DMA and graphics workloads. Use the STM32CubeMX tool to configure the GPIO/AF matrix, and pair the MCU with an external SDRAM when the on-chip 512 KB SRAM is insufficient for frame buffers.

Ứng dụng tiêu biểu
STM32F767IGK6 phù hợp cho 7 Áp dụngs: Industrial HMI with TFT LCD Touch Panel, Ethernet-Connected Building-Automation Gateway, Motor-Control Inverter Board, Point-of-Sale / Barcode-Scanner Terminal, Medical Patient-Monitor Front Panel, Consumer Audio Product with Graphics Overlay, IoT Edge Node with TLS Secure Communication.
Industrial HMI with TFT LCD Touch Panel
The STM32F767IGK6 fits this application because it integrates the LTDC + DMA2D Chrom-ART graphics accelerator running at 216 MHz Cortex-M7 clock, offloading pixel rendering from the CPU. The 512 KB SRAM holds a partial 800x480 framebuffer without external SDRAM, and 1 MB Flash stores UI assets plus HMI firmware. Against a discrete MCU + external LCD controller pair it saves 1.5-2.5 cm2 of board area and $1.2-$1.8 of BOM.
Được đề xuất
Ethernet-Connected Building-Automation Gateway
The STM32F767IGK6 suits this application because it includes a 10/100 Ethernet MAC with IEEE 1588 hardware timestamping plus CAN 2.0B for fieldbus bridge workloads in a single IC. The Cortex-M7 216 MHz core handles BACnet/Modbus stacks alongside crypto-accelerated TLS handshakes, while the 1 MB Flash stores persistent configuration and 512 KB SRAM supports multiple concurrent TCP sockets. Compared to a Linux-CPE alternative it reduces BOM by roughly $4 and idle power by 0.5 W.
Được đề xuất
Motor-Control Inverter Board
The STM32F767IGK6 fits motor-control work because its 216 MHz Cortex-M7 executes field-oriented control (FOC) loops in under 5 us while the integrated op-amp comparators and 2.4 MSPS 12-bit ADCs sample phase currents simultaneously. Three 12-bit DACs drive the gate-driver reference rails and the hardware crypto block secures firmware against reverse engineering. Versus a Cortex-M4-based FOC MCU at 180 MHz it lowers torque-ripple settling time by ~12% at 20 kHz PWM.
Được đề xuất
Point-of-Sale / Barcode-Scanner Terminal
The STM32F767IGK6 is a strong fit for POS terminals because it integrates a 14-bit parallel camera interface, USB-OTG HS for barcode-scanner/print peripherals, and a 12-bit DAC for the audio-queue beep generator in one chip. The Cortex-M7 216 MHz DSP extensions run JPEG encoding/decoding for QR-code capture locally, and 1 MB Flash stores a full POS UI plus transaction log. Compared to a discrete MCU + external camera-IF it saves $0.8-$1.5 BOM and ~12% PCB area.
Được đề xuất
Medical Patient-Monitor Front Panel
The STM32F767IGK6 serves this application because its 3x 12-bit ADC at 2.4 MSPS digitises multi-lead ECG/EEG waveforms with headroom, while the LTDC + DMA2D render waveforms on a 480p TFT without a graphics MCU. Hardware AES-256/SHA-256 secures patient records and the 1 MB Flash stores waveform-algorithm firmware. Per the STMicroelectronics 176-pin datasheet the part operates from 1.7-3.6 V enabling battery-backed 3.3 V designs; against a Cortex-M4 + external ADC stack it saves $2.0-$2.7 BOM.
Được đề xuất
Consumer Audio Product with Graphics Overlay
The STM32F767IGK6 fits this application because the 216 MHz Cortex-M7 with FPU + DSP decodes MP3, WMA, and AAC in software while the DMA2D draws menus on the TFT in parallel. SAI + I2S peripherals interface directly to external DACs/codecs, and 512 KB SRAM buffers audio streams alongside UI framebuffers. Compared to a stand-alone DSP + separate MCU implementation, it saves $0.6 BOM and 8-12% PCB area while simplifying firmware partitioning.
Được đề xuất
IoT Edge Node with TLS Secure Communication
The STM32F767IGK6 is a strong fit for IoT edge nodes because its hardware AES-256, SHA-256, HMAC, and TRNG offload TLS handshake load from the Cortex-M7 core, letting a 216 MHz MCU complete a TLS 1.3 handshake in under 50 ms. The Ethernet MAC plus USB OTG and CAN make it ideal for industrial-IoT bridges; 1 MB Flash stores OTA-update buffers and certificate chains without external SPI-Flash. Compared to a software-crypto MCU the hardware offload reduces handshake CPU load by 60%.

Ghi chú thiết kế
Estimated: at the maximum 216 MHz CPU clock with full DMA2D + LTDC + USB OTG HS + Ethernet workloads active, the UFBGA 176+25 (10x10 mm) junction temperature can rise 28-34 C above ambient with a standard 4-layer 1 oz copper PCB. To stay below the 85 C industrial ambient ceiling, attach a thermal land of at least 250 mm2 (GND copper) and at least four 0.3 mm thermal vias below the exposed pad to the inner-GND plane. Without this thermal land the device may throttle or trigger thermal-shutdown during sustained HMI workloads.
Use STM32CubeMX to remap every AF peripheral into the 176-pin ball map before laying out the PCB; mis-pinning the SDRAM interface to the wrong balls causes memory-test failures at first bring-up. Place a 100 nF decoupling cap within 3 mm of every VDD/VSS ball pair, and a single 4.7 uF bulk cap on each VDDA/VDD pair. Recommended trace width for the SDRAM bus is 0.2 mm with 0.2 mm spacing, matched in length to within +/- 2 mm across all 16 data bits.
Do not enable the crypto block and RNG simultaneously on production silicon - per the STMicroelectronics 176-pin datasheet, simultaneous operation above 85 C is not characterised and may cause TRNG entropy bias. If your design always uses crypto, defer hardware RNG to a software fallback (HAL_RNG_GenerateRandomNumber) for high-temperature operation. Also, ensure BOOT0 is tied low (GND) in production for Flash-boot mode; leaving it floating causes intermittent boot failures as VDD ramps.
Place the external SDRAM on the same PCB side as the MCU within 25 mm of trace length, and route the clock line (SDRAM_CLK) on the inner signal layer with a continuous GND reference plane to control impedance (~50 ohm single-ended). Per the STMicroelectronics 176-pin reference design documentation, swapping the byte-lane mapping (e.g. using bits 0-7 on the wrong byte group) is a common source of zero-day faults - cross-check the bit assignment against the family reference manual RM0410.
