Product details

Overview

STM32U585RIT6QTR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, 240 DMIPS performance, 2 MB Flash (ECC), 786 KB SRAM, and integrated crypto accelerators (AES, PKA, HASH, RNG). It operates from 1.71–3.6 V across –40 °C to +125 °C and delivers 4.3 µA Stop 3 mode with full SRAM retention-ideal for battery-powered industrial sensors and secure IoT edge nodes.

For engineers reviewing the STM32U585RIT6QTR datasheet, STM32U585RIT6QTR pinout, STM32U585RIT6QTR application, or STM32U585RIT6QTR equivalent, key selection criteria include TrustZone-enabled secure boot, LPBAM autonomous peripheral operation in Stop 2 mode, dual Octo-SPI interfaces for encrypted external memory, and 14-bit/12-bit ADCs with hardware oversampling for precision sensing.

Technical Context

The device implements a dual-cache ART Accelerator (8 KB instruction cache, 4 KB data cache) enabling zero-wait-state execution at up to 160 MHz. Its power architecture integrates both LDO and SMPS step-down converters with on-the-fly voltage scaling, supporting dynamic transition between Run, Stop 2, Stop 3, Standby, and Shutdown modes.

Security is architected around Arm TrustZone®, SESIP3/PSA Level 3 certification, and hardware root-of-trust features including secure hide protection area (HDP), unique boot entry, and embedded Root Secure Services (RSS) for secure firmware installation and OTA updates.

Pinout & Package

STM32U585RIT6QTR is housed in a 64-pin LQFP64 package (10 × 10 mm, 0.5 mm pitch), compatible with standard PCB assembly processes and offering full I/O access for complex peripheral routing.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VDDA, VDDIO2	Power supply inputs	Dedicated domains for core, analog, and I/O-enables independent voltage scaling and noise isolation for mixed-signal integrity.
VSS, VSSA, VSSIO2	Ground returns	Separate ground planes minimize coupling between digital switching noise and sensitive analog/ADC paths.
PA0–PA15, PB0–PB15, etc.	General-purpose I/Os	Up to 136 fast GPIOs (most 5V-tolerant); 14 support independent 1.08–3.6 V supply - allows direct interfacing with legacy logic and low-voltage peripherals.
PC13–PC15	RTC/LSE interface	Supports 32.768 kHz crystal oscillator for calendar RTC with hardware calibration - critical for time-stamped logging and wake-up scheduling.
PF0–PF1	System reset & boot configuration	NRST input and BOOT0/BOOT1 pins define reset behavior and boot source (Flash, system memory, or SRAM) - essential for field firmware recovery and secure boot enforcement.

Key Features

Feature	Design Value
LPBAM (Low-Power Background Autonomous Mode)	Enables DMA-driven peripheral chains (e.g., ADC → DMA → memory) while CPU remains in Stop 2 - eliminates wake-up latency for continuous sensor sampling.
Octo-SPI with OTFDEC	On-the-fly decryption of external NOR/FRAM memories using AES-128/256 - allows secure code execution from external storage without exposing plaintext firmware.
Chrom-ART Accelerator (DMA2D)	Hardware-accelerated 2D graphics rendering (copy, blend, fill) - reduces CPU load in HMI applications with LCD/TFT displays.
CORDIC + FMAC coprocessors	Hardware acceleration for trigonometric (sin/cos/tan) and filter coefficient computation - improves real-time motor control and audio preprocessing efficiency.
Tamper detection & backup domain	Active tamper pins + VBAT-supplied RTC, 32×32-bit backup registers, and 2 KB backup SRAM - preserves critical state during main power loss or physical intrusion attempts.

Applications

Medical Wearable Sensor Hub

Automotive Body Control Module (BCM)

Use Scenario: ECG/PPG patch collecting biometric signals, performing local artifact filtering, and transmitting HIPAA-compliant data via Bluetooth LE.

IC Role / Device Role / Timing Role: Signal acquisition hub with 14-bit ADC oversampling, CORDIC-based QRS detection, and secure BLE pairing using hardware TRNG and AES.

Use Value: 4.3 µA Stop 3 mode preserves SRAM context during sleep between heartbeats; 2 op-amps with PGA condition analog biosignals directly on-chip, reducing BOM count.

Use Scenario: Low-power BCM controlling door locks, lighting, HVAC, and diagnostics in 12 V automotive systems with ASIL-B functional safety requirements.

IC Role / Device Role / Timing Role: Safety-aware MCU executing ISO 26262-compliant diagnostics, CAN FD communication, and watchdog supervision with dual-core lockstep not required due to hardware ECC and fault injection hardening.

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
STM32L562RET6	Same Cortex-M33 core but lacks Octo-SPI, OTFDEC, UCPD, and only 512 KB Flash - no on-the-fly external memory decryption or USB Type-C PD control.	Targeted at cost-sensitive secure applications without external code storage or USB-C power negotiation needs.	Select when external memory encryption and USB-C PD are unnecessary, and lower Flash/SRAM capacity suffices.
RA6M5GFPMCBG	Renesas RA6M5 offers 1 MB Flash, 480 MHz Cortex-M33, but no TrustZone-certified PSA Level 3 assurance, no LPBAM, and higher active current (28 µA/MHz).	Suitable for high-performance industrial HMI where security certification is less critical than GUI throughput.	Choose for richer graphics (2D GPU) and faster CPU, but only if PSA Level 3 certification and sub-µA low-power modes are not mandatory.

Compared with STM32L562RET6, the STM32U585RIT6QTR adds critical secure boot and encrypted external memory capabilities; versus RA6M5GFPMCBG, it delivers superior ultra-low-power autonomy and certified security for regulated IoT deployments.

FAQ

What is the maximum operating temperature range for STM32U585RIT6QTR?

The STM32U585RIT6QTR is qualified for operation from –40 °C to +125 °C ambient temperature, meeting industrial and extended automotive under-hood requirements. This rating is verified per JEDEC JESD22-A104 and applies across all supported low-power modes and clock configurations.

Does STM32U585RIT6QTR support hardware-accelerated TLS 1.2/1.3?

Yes - the device integrates SAES (AES-128/256), PKA (RSA/ECC), HASH (SHA-256), and TRNG compliant with NIST SP800-90B, enabling full TLS handshake acceleration in software stacks like Mbed TLS or WolfSSL. No external crypto co-processor is needed for secure socket layer operations.

How many wake-up pins are available in Shutdown mode?

STM32U585RIT6QTR provides 24 dedicated wake-up pins in Shutdown mode, each capable of generating a system wake event from 160 nA quiescent current. These pins retain interrupt capability and can be configured as level- or edge-sensitive inputs without CPU intervention.

Is the 2 MB Flash memory organized in dual banks with read-while-write capability?

Yes - the 2 MB Flash is split into two independent banks, allowing concurrent read from one bank while programming or erasing the other. This enables seamless firmware updates and real-time code execution during Over-The-Air (OTA) upgrades without service interruption.
