Product details

Overview

STM32U595ZIY6QTR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, FPU, and integrated graphics acceleration (Neo-Chrom GPU, Chrom-ART), delivering 240 DMIPS at up to 160 MHz. It features 4 MB Flash with ECC, 2.5 MB SRAM (with configurable ECC), MIPI® DSI host controller (2 lanes @ 500 Mbit/s), LTDC, and operates from 1.71 V to 3.6 V across –40 °C to +125 °C. It targets secure, battery-constrained UI-rich edge devices such as smart thermostats and portable medical displays.

For engineers reviewing the STM32U595ZIY6QTR datasheet, STM32U595ZIY6QTR pinout, STM32U595ZIY6QTR application, or STM32U595ZIY6QTR equivalent, key selection criteria include TrustZone-enabled secure boot, LPBAM autonomous peripheral operation in Stop 2 mode, 18.5 µA/MHz Run current at 3.3 V, dual 14-bit ADCs (2.5 Msps), and MIPI DSI + LTDC coexistence for high-fidelity embedded displays.

Technical Context

The device integrates a dual-cache Arm Cortex-M33 core (32 KB I-Cache, 16 KB D-Cache1) with TrustZone partitioning, enabling hardware-isolated secure and non-secure firmware execution. Its FlexPowerControl architecture supports seven low-power modes-including 480 nA Standby with RTC and 2 µA Stop 3 with 40 KB SRAM-managed via embedded SMPS and LDO regulators with dynamic voltage scaling.

Graphics subsystem includes Neo-Chrom GPU (GPU2D) for rotation/scaling, Chrom-ART Accelerator (DMA2D) for alpha-blending and memory-to-memory transfers, and Chrom-GRC (GFXMMU) for resource optimization. The MIPI DSI host controller supports two high-speed lanes (500 Mbit/s each), while LTDC drives RGB/TTL panels up to 24-bit color depth at 60 Hz.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power secure MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32U575ZIT6Q	Same Cortex-M33 core and TrustZone, but 2 MB Flash, 1 MB SRAM, no MIPI DSI, no Neo-Chrom GPU, only single OCTOSPI.	Suitable for secure sensor hubs or BLE gateways without embedded display - lacks DSI/LTDC/GPU required for local UI.	Select when display capability is unnecessary and cost/size reduction is prioritized over graphics throughput.
NXP i.MX RT1189CVM8B	Arm Cortex-M85 core, 1.5 GHz, 2 MB SRAM, no TrustZone (uses SECO), dual LVDS/eDP display outputs, no integrated SMPS.	Targets higher-performance industrial displays with Linux support - requires external PMIC and lacks sub-µA low-power modes.	Select for Linux-capable edge AI inference with display, not for battery-constrained TrustZone-first designs.

Compared with STM32U575ZIT6Q, the STM32U595ZIY6QTR adds MIPI DSI, LTDC, GPU2D, and 2× more Flash/SRAM - essential for standalone rich UIs. Versus i.MX RT1189CVM8B, it trades raw speed for certified ultra-low-power operation and integrated security - better suited for Class I medical or energy-harvested deployments.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32U595ZIY6QTR runs at up to 160 MHz with an ART Accelerator enabling zero-wait-state execution from Flash. Its performance is quantified at 240 DMIPS (Dhrystone 2.1), 655 CoreMark® (4.09 CoreMark®/MHz), and 369 ULPMark™-CP - benchmark values measured under specified voltage and temperature conditions per DS13633 Rev 3.

Does this MCU support secure boot and runtime firmware validation?

Yes. It implements a hardware-rooted secure boot chain using TrustZone, a secure hide-protection area (HDP), and embedded Root Secure Services (RSS). Secure Firmware Installation (SFI) validates signed firmware images at boot and runtime, and supports TF-M for PSA Certified Level 3 compliance - all documented in sections 3.6 and 3.54 of the datasheet.

What display interfaces does the STM32U595ZIY6QTR support simultaneously?

It supports MIPI DSI (2 lanes @ 500 Mbit/s) and LCD-TFT Controller (LTDC) concurrently. The Chrom-GRC (GFXMMU) manages shared memory bandwidth between them, allowing simultaneous DSI panel driving and LTDC-based RGB output - verified in functional overview section 3.19–3.21 and electrical characteristics table 5.3.33.

How many wake-up pins are available in Shutdown mode, and what is the typical current draw?

In Shutdown mode, 24 dedicated wake-up pins are available, and the typical current consumption is 150 nA at 3.3 V and 25 °C - specified in Table 5 of the datasheet (DS13633 Rev 3, page 183) under "Shutdown mode with VDD/VDDA powered off".
