Product details
Overview
STM32U595ZIT6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit MCU with TrustZone® and FPU, delivering 240 DMIPS at up to 160 MHz. It integrates 4 MB Flash with ECC, 2.5 MB SRAM (with configurable ECC), MIPI® DSI host controller, LTDC, Neo-Chrom GPU, and dual 14-bit ADCs-targeting secure, graphics-rich IoT edge nodes and battery-powered HMI applications.
For engineers reviewing the STM32U595ZIT6 datasheet, STM32U595ZIT6 pinout, STM32U595ZIT6 application, or STM32U595ZIT6 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, and dual Octo-SPI interfaces for external memory expansion.
Technical Context
The STM32U595ZIT6 implements a dual-bank Flash architecture with read-while-write capability and hardware ECC, enabling robust firmware updates and secure code execution. Its FlexPowerControl system 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.
TrustZone® partitions memory and peripherals into secure/non-secure worlds, enforced by GTZC and securable I/Os; cryptographic acceleration includes HASH, CORDIC, FMAC, and NIST SP800-90B–compliant TRNG. The Neo-Chrom GPU and Chrom-ART Accelerator (DMA2D) offload 2D graphics rendering, while MIPI DSI (dual 500 Mbit/s lanes) and LTDC drive high-resolution displays directly.

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 |
|---|---|---|---|
| STM32U575ZIT6 | Same core and peripherals but limited to 2 MB Flash, 1 MB SRAM, no MIPI DSI, and no Neo-Chrom GPU. | Suitable for secure sensor nodes without display requirements-lacks graphics acceleration and high-res display interfaces. | Select when display functionality is unnecessary and cost/BOM simplification is prioritized over GUI capability. |
| RA8T1M20GBM#AC0 | Renesas RA8 series with Cortex-M85, 2 MB Flash, 1.5 MB SRAM, and 2D graphics accelerator-but no TrustZone, no MIPI DSI, and higher active current (28 µA/MHz). | Targets real-time motor control with GUI; lacks PSA-certified security architecture and ultra-low-power standby modes. | Choose only if Armv8.1-M vector extensions or specific Renesas ecosystem tools outweigh STM32U595's security and power advantages. |
Compared with STM32U575ZIT6 and RA8T1M20GBM#AC0, the STM32U595ZIT6 uniquely combines PSA Level 3–certifiable TrustZone, sub-µA standby, MIPI DSI, and Neo-Chrom GPU-making it the only option for battery-powered, secure, high-resolution HMI endpoints requiring field-upgradable firmware and tamper resistance.

FAQ
What is the maximum operating temperature range for the STM32U595ZIT6?
The STM32U595ZIT6 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 automotive under-hood modules, industrial PLCs, and outdoor environmental sensors without derating.
Does the STM32U595ZIT6 support hardware-based secure boot with public-key verification?
Yes-the device implements a root of trust using a unique boot entry point, secure hide-protection area (HDP), and embedded root secure services (RSS). It validates ECDSA-signed firmware images during reset, enforcing immutable secure boot before any user code executes.
Can the MIPI DSI interface operate independently of the LTDC controller?
No-the MIPI DSI host controller requires LTDC as its pixel source; LTDC generates the video timing and pixel stream fed into DSI for serialization. However, DSI can transmit command packets (e.g., display sleep/wake) without active LTDC video output.
How many wake-up pins are available in Shutdown mode?
The STM32U595ZIT6 provides 24 dedicated wake-up pins in Shutdown mode, all capable of generating a reset or exit event from the 150 nA state. These include all GPIOs except those multiplexed with JTAG/SWD debug pins (e.g., PA13/PA14), as confirmed in Section 3.9.3 of DS13633 Rev 3.
