STMicroelectronics STM32MP135DAF7

Overview

STM32MP135DAF7 from STMicroelectronics is a dual-core Arm® Cortex®-A7 microprocessor unit (MPU) operating up to 1 GHz, integrating LCD-TFT controller, dual CAN FD interfaces, dual 12-bit ADCs (5 Msps), and dual Gigabit Ethernet MACs. It supports LPDDR3-1066/DDR3L-1066 memory, TrustZone® security, and is designed for industrial HMI, edge gateway, and smart camera applications requiring real-time multimedia processing and secure connectivity.

For engineers reviewing the STM32MP135DAF7 datasheet, STM32MP135DAF7 pinout, STM32MP135DAF7 application, or STM32MP135DAF7 equivalent, key selection considerations include DDR memory interface timing compliance, CAN FD protocol stack support, LCD-TFT pixel clock capability (up to 90 MHz), and TrustZone-enabled peripheral isolation in heterogeneous Linux-based systems.

Technical Context

The STM32MP135DAF7 implements a dual-core Arm Cortex-A7 subsystem with 128 KB unified L2 cache, NEON™ SIMD extension, and TrustZone® for hardware-enforced secure/non-secure world separation. Its interconnect matrix comprises a 64-bit AXI bus (266 MHz) and 32-bit AHB bus (209 MHz), enabling concurrent high-bandwidth data movement between CPU, DMA, and peripherals.

It integrates two independent FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), supporting bit rates up to 5 Mbit/s and payloads up to 64 bytes. The LCD-TFT controller delivers WXGA (1366×768) at 60 fps or Full HD (1920×1080) at 30 fps with dual programmable layers and hardware color LUT, directly driving RGB888 panels without external frame buffer.

FAQ

What boot sources does the STM32MP135DAF7 support?

The STM32MP135DAF7 supports boot from internal ROM (with configurable fallback), Quad-SPI NOR flash, SD/eMMC, NAND flash via FMC, and USB device mode. Boot mode is selected by BOOT0 and BOOT1 pins at power-on reset, and the first-stage bootloader (FSBL) validates signature and loads second-stage firmware from trusted storage.

Does STM32MP135DAF7 include hardware cryptographic acceleration?

Yes-it integrates dedicated hardware accelerators for SHA-224/256/384/512, HMAC, ECDSA signature verification, and a true random number generator (TRNG) with three independent oscillators. These operate independently of the Cortex-A7 cores and are accessible via TrustZone-protected drivers in Linux kernel 5.10+.

What is the maximum resolution and refresh rate supported by the LCD-TFT controller?

The LCD-TFT controller supports up to Full HD (1920 × 1080) at 30 fps or WXGA (1366 × 768) at 60 fps, with a maximum pixel clock of 90 MHz. It provides two overlay layers (one secured), programmable color LUT, and RGB888 interface-no external frame buffer required for basic operation.

How many CAN FD interfaces does STM32MP135DAF7 provide, and what protocols do they support?

The STM32MP135DAF7 integrates two fully independent FDCAN controllers compliant with ISO 11898-1:2015, supporting Classical CAN, CAN FD (up to 5 Mbit/s data phase), and optional ISO 11898-2/3 physical layer compatibility. Each includes dedicated message RAM, filtering, and loopback self-test modes.
