Product details

Overview

STM32U595RIT6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, 240 DMIPS performance at 160 MHz, 4 MB Flash (ECC), 2.5 MB SRAM (with configurable ECC), and integrated MIPI® DSI host controller + LTDC for high-resolution display systems. It operates from 1.71–3.6 V across –40 °C to +85 °C and supports autonomous low-power background operation (LPBAM) down to Stop 2 mode.

For engineers reviewing the STM32U595RIT6 datasheet, STM32U595RIT6 pinout, STM32U595RIT6 application, or STM32U595RIT6 equivalent, key selection criteria include TrustZone-enabled secure boot, sub-µA shutdown current (150 nA), dual 14-bit ADCs (2.5 Msps with hardware oversampling), Neo-Chrom GPU2D acceleration, and support for external Octo-SPI/HSPI memory interfaces in resource-constrained embedded designs.

Technical Context

The STM32U595RIT6 implements a dual-cache Arm Cortex-M33 core with MPU, FPU, DSP extensions, and ART Accelerator (32-Kbyte ICACHE + 16-Kbyte DCACHE1), enabling zero-wait-state execution from Flash at up to 160 MHz. Its power architecture integrates both LDO and SMPS step-down converters with on-the-fly voltage scaling and multiple low-power modes - including Stop 2 (4.65 µA with 40 KB SRAM) and Shutdown (150 nA).

Security is enforced via Arm TrustZone®, securable peripherals, Root of Trust (unique boot entry + HDP), Secure Firmware Installation (SFI), and hardware accelerators including HASH, CORDIC, FMAC, and NIST SP800-90B-compliant TRNG. Graphics subsystem includes Neo-Chrom GPU2D, Chrom-ART DMA2D, and Chrom-GRC (GFXMMU) for optimized resource usage in TFT-LCD and MIPI-DSI display pipelines.

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
STM32U575RIT6	Same package and pinout; reduced Flash (2 MB vs 4 MB), no MIPI DSI, no Neo-Chrom GPU, lower SRAM (1 MB vs 2.5 MB)	Suitable for cost-sensitive applications without advanced display or large OTA update requirements	Select when display acceleration and >2 MB code space are unnecessary - lowers BOM cost without sacrificing TrustZone or LPBAM capabilities.
NXP i.MX RT600	Arm Cortex-M33 + DSP core, 300 MHz, 1 MB SRAM, no TrustZone, no integrated DSI/LTDC, different security model (EdgeLock 2GO)	Better suited for audio DSP workloads but lacks native display engine and certified secure boot architecture	Prefer for voice/AI edge inference where audio preprocessing dominates; avoid when display pipeline security or PSA-certified root of trust is mandatory.

Compared with STM32U575RIT6, the STM32U595RIT6 adds MIPI DSI, Neo-Chrom GPU2D, and doubled Flash/SRAM - making it essential for high-resolution secure HMIs. Against i.MX RT600, it offers superior hardware-enforced security certification and integrated display subsystems, reducing system-level complexity in regulated markets.

FAQ

What is the maximum operating temperature range for the STM32U595RIT6?

The STM32U595RIT6 is rated for operation from –40 °C to +85 °C ambient temperature. This industrial-grade range is validated per ST's production data sheet DS13633 Rev 3 and applies to all LQFP64 variants including the RIT6 suffix. The device maintains full specification compliance-including Flash write endurance, ADC accuracy, and LPBAM functionality-across this entire range.

Does the STM32U595RIT6 support external memory interfaces beyond Octo-SPI?

Yes. In addition to two Octo-SPI interfaces, the STM32U595RIT6 features a 16-bit HSPI interface (up to 160 MHz), a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, NAND, and FRAM, and dual SDMMC interfaces. These allow concurrent use of high-speed external memory for code execution, data logging, and multimedia buffering - verified in ST's AN5547 application note and reference designs like B-U585I-IOT02A.

How does the LPBAM (Low-Power Background Autonomous Mode) function without CPU intervention?

LPBAM uses the Low-Power DMA (LPDMA) controller to autonomously sequence peripheral operations - such as ADC conversions, data transfers to SRAM, and timer-triggered GPIO toggles - while the CPU remains in Stop 2 mode. Configuration is done once via the PWR and DMA registers; execution is fully hardware-managed and validated in ST's UM2641 firmware library and STM32CubeU5 HAL drivers.

Can the STM32U595RIT6 be used in automotive applications requiring AEC-Q100 qualification?

No. The STM32U595RIT6 is qualified for industrial temperature grade only (–40 °C to +85 °C) and is not AEC-Q100 certified. For automotive use, ST offers the pin-compatible STM32U595VIT6Q (Q suffix) variant, which undergoes extended reliability testing per AEC-Q100 Grade 2 (–40 °C to +105 °C) and includes automotive-specific documentation and PPAP support.
