STMicroelectronics STM32F469AGY6TR

Overview

STM32F469AGY6TR from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit microcontroller with FPU and ART Accelerator™, operating up to 180 MHz (225 DMIPS), featuring 1 MB flash, 384+4 KB SRAM (including 64 KB CCM), integrated Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller (720p/30 Hz), and dual USB OTG (FS + HS) with dedicated DMA. It targets embedded HMI systems requiring real-time graphics, camera input, and industrial connectivity.

For engineers reviewing the STM32F469AGY6TR datasheet, STM32F469AGY6TR pinout, STM32F469AGY6TR application, or STM32F469AGY6TR equivalent, key selection criteria include MIPI DSI support, dual Quad-SPI interface, LCD-TFT + DCMI coexistence, Ethernet MAC with IEEE 1588v2 hardware timestamping, and 161 I/Os with 5 V tolerance - critical for scalable HMI and vision-enabled edge devices.

Technical Context

The STM32F469AGY6TR integrates an adaptive real-time memory accelerator (ART Accelerator™) enabling zero-wait-state execution from flash at 180 MHz, alongside a dedicated Chrom-ART Accelerator™ (DMA2D) that offloads 2D graphics composition from the CPU. Its dual-bank flash architecture supports true read-while-write operation, essential for secure firmware updates without system interruption.

It features a full-featured peripheral set including dual CAN 2.0B controllers, 10/100 Ethernet MAC with MII/RMII and IEEE 1588v2 hardware support, and a parallel 8–14-bit camera interface capable of 54 MB/s throughput - all synchronized via a multi-AHB bus matrix and 16-stream DMA controller with FIFO buffering.

Key Specifications

Pinout & Package

STM32F469AGY6TR is housed in a 176-ball Ultra-Fine-Pitch Ball Grid Array (UFBGA176) package measuring 10 mm × 10 mm with 0.8 mm ball pitch. This RoHS-compliant, halogen-free package supports high-density PCB layouts and thermal dissipation via exposed thermal pad (EPAD).

FAQ

What is the maximum resolution supported by the MIPI DSI interface on STM32F469AGY6TR?

The MIPI DSI host controller supports up to 720p (1280×720) at 30 Hz with 1–4 data lanes and compliant D-PHY v1.2 timing. It does not support 1080p natively; achieving higher resolutions requires external timing controllers or bridge ICs, as confirmed in Section 2.12 and Table 5.3.13 of DS11189 Rev 8.

Does STM32F469AGY6TR support hardware encryption acceleration?

No, the STM32F469AGY6TR does not include dedicated AES, DES, or SHA hardware accelerators. It features a true random number generator (RNG) and CRC calculation unit, but cryptographic operations rely on software libraries or external secure elements, as documented in Sections 2.38 and 2.5 of the datasheet.

Can the STM32F469AGY6TR run from internal RC oscillators without external crystals?

Yes - it includes factory-trimmed 16 MHz HSI (±1% accuracy) and 32 kHz LSI for RTC, enabling crystal-free operation in non-precision timing applications. However, USB HS, Ethernet, and MIPI DSI require external clock sources (4–26 MHz HSE or dedicated PLL inputs), per Sections 2.16 and 5.3.10.

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

VCAP1 and VCAP2 connect to external 2.2 µF ceramic decoupling capacitors (X7R, 10% tolerance, 6.3 V rating) that stabilize the internal 1.2 V voltage regulator. Omitting or undersizing these capacitors causes unstable operation above 120 MHz, as specified in Section 5.3.2 and Table 19 of DS11189 Rev 8.
