STMicroelectronics STM32U595VJT6

Overview

STM32U595VJT6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, FPU, and 240 DMIPS performance at up to 160 MHz. It integrates 4 MB Flash (with ECC), 2.5 MB SRAM (including 322 KB with ECC), LTDC display controller, MIPI® DSI host, Neo-Chrom GPU2D, and dual 14-bit ADCs-designed for secure, graphics-rich battery-powered IoT edge nodes and industrial HMIs.

For engineers reviewing the STM32U595VJT6 datasheet, STM32U595VJT6 pinout, STM32U595VJT6 application, or STM32U595VJT6 equivalent, key selection criteria include TrustZone-enabled secure boot, LPBAM autonomous peripheral operation in Stop 2 mode, 18.5 µA/MHz Run-mode efficiency, 2.5 MB SRAM retention, and MIPI DSI + LTDC coexistence for embedded display subsystems.

Technical Context

The STM32U595VJT6 implements a dual-bank Flash architecture with read-while-write capability and hardware ECC, enabling secure over-the-air firmware updates without execution interruption. Its FlexPowerControl system supports seven low-power modes-including Stop 2 (4.65 µA with 40 KB SRAM) and Shutdown (150 nA)-with 24 wake-up pins and VBAT-supplied RTC/backup registers.

TrustZone® partitions memory, peripherals, and I/Os into Secure and Non-Secure worlds, enforced by the Global TrustZone Controller (GTZC) and securable SYSCFG. The device includes dedicated cryptographic accelerators: HASH, TRNG (NIST SP800-90B compliant), and embedded Root Secure Services (RSS) for TF-M–based secure firmware installation and upgrade.

FAQ

What is the maximum operating temperature for the STM32U595VJT6?

The STM32U595VJT6 is rated for operation from –40 °C to +125 °C ambient temperature, validated per DS13633 Rev 3 Section 5.3.1. This extended range supports deployment in harsh industrial enclosures and automotive under-hood environments without derating.

Does the STM32U595VJT6 support external SDRAM?

Yes - the Flexible Static Memory Controller (FSMC) supports external SDRAM, PSRAM, NOR, NAND, and FRAM. The LQFP100 package exposes all required address/data/control lines (PH0–PH15, PD0–PD15, PG0–PG15), enabling up to 64 MB SDRAM expansion with configurable burst length and refresh timing.

How does LPBAM reduce power in sensor acquisition?

LPBAM configures peripherals (e.g., ADC, timers, DMA) to operate autonomously in Stop 2 mode without CPU intervention. For example, an ADC can trigger on timer events, store samples to SRAM via DMA, and wake the CPU only after 1024 samples - cutting average current from ~17.5 µA to 4.65 µA during acquisition.

Can the MIPI DSI and LTDC be used simultaneously?

Yes - the STM32U595VJT6 supports concurrent MIPI DSI and LTDC operation. The LTDC drives parallel RGB panels while MIPI DSI controls high-resolution DSI panels; both share the Neo-Chrom GPU2D and Chrom-ART Accelerator (DMA2D) for unified graphics composition and overlay blending.
