STMicroelectronics STM32F765IGK6

Overview

STM32F765IGK6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with integrated FPU, delivering 462 DMIPS at 216 MHz, 2 MB flash (dual-bank), 512 KB SRAM (including 128 KB data TCM), and advanced graphics acceleration via Chrom-ART and hardware JPEG codec. It integrates MIPI DSI host controller (720p30), LCD-TFT controller (XGA), USB OTG HS/FS, 10/100 Ethernet MAC with IEEE 1588v2 support, and three CAN 2.0B interfaces - deployed in industrial HMI, medical imaging front-ends, and connected gateway controllers.

For engineers reviewing the STM32F765IGK6 datasheet, STM32F765IGK6 pinout, STM32F765IGK6 application, or STM32F765IGK6 equivalent, key selection considerations include dual-bank flash for robust firmware updates, TCM RAM allocation for deterministic real-time control loops, DSI/LCD timing compliance for embedded display subsystems, and Ethernet+CAN coexistence for multi-protocol industrial edge nodes.

Technical Context

The STM32F765IGK6 implements a tightly coupled memory architecture with separate 16 KB I/D L1 caches and ART Accelerator, enabling zero-wait-state execution from flash or external memories. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, FMC, and peripherals - critical for real-time graphics rendering and simultaneous communication stack operation.

It features a dual-mode Quad-SPI interface for XIP or memory-mapped external flash, a dedicated SDMMC controller supporting eMMC 4.51 and SDIO 3.0, and three independent CAN FD-capable bxCAN controllers (2.0B Active) with time-triggered communication support - all synchronized via a multi-source clock system including PLLSAI for audio/LCD and PLLI2S for SAI/SPDIFRX.

Key Specifications

Pinout & Package

LQFP100 (14 × 14 mm, 0.5 mm pitch) package with 100 pins; RoHS-compliant ECOPACK2. Pin count and signal mapping validated per STMicroelectronics datasheet DS11532 Rev 9, Section 4 "Pinouts and pin description" and Table 11 "Pin and ball definitions".

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance MCU applications.

Compared with STM32F767ZIT6, the STM32F765IGK6 offers identical processing capability in a smaller LQFP100 package but omits FMC - ideal for display-centric designs without external memory. Versus STM32H743VIT6, it trades raw compute for mature display/audio IP and lower power consumption at 216 MHz, making it more suitable for cost-sensitive, graphics-intensive industrial HMIs.

FAQ

What is the maximum operating frequency and corresponding power supply requirement for STM32F765IGK6?

The STM32F765IGK6 operates at up to 216 MHz when supplied with 3.3 V (±5%) and ambient temperature ≤85 °C. At this frequency, VDD must be ≥2.7 V per DS11532 Rev 9 Section 6.3.1; below 2.7 V, maximum frequency is reduced to maintain timing margins and prevent core instability.

Does STM32F765IGK6 support hardware encryption or secure boot features?

No - the STM32F765IGK6 does not integrate AES, SHA, or public-key accelerators, nor does it support hardware root-of-trust or secure boot. For secure firmware validation, external secure elements (e.g., STSAFE-A110) or software-based signature verification using its TRNG and CRC units are required.

Can the DSI host interface drive a 1080p display?

No - the DSI host controller is specified for up to 720p at 30 Hz (1280×720, 30 fps) per DS11532 Rev 9 Section 3.47. Driving 1080p would exceed its pixel clock limit of 150 MHz and lane bandwidth; use external DSI-to-LVDS bridge ICs or select STM32F769xx variants with higher DSI capability.

What is the purpose of the VCAP1 and VCAP2 pins, and what capacitor value is required?

VCAP1 and VCAP2 connect to the internal voltage regulator's stabilization capacitors. Each requires a 2.2 µF ±10% X7R ceramic capacitor placed within 5 mm of the pin and referenced to VSS, as specified in DS11532 Rev 9 Section 6.3.2. Omission or undersizing causes boot failure or intermittent FPU exceptions under load.
