Product details

Overview

STM32H533HEY6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M33 microcontroller with TrustZone® security, FPU, and 250 MHz max clock frequency. It integrates 512 Kbytes of ECC-protected flash, 272 Kbytes of SRAM (80 Kbytes with ECC), and hardware cryptographic accelerators including dual AES coprocessors and PSA Level 3-certified security. It targets secure industrial control, IoT edge nodes, and trusted firmware execution environments.

For engineers reviewing the STM32H533HEY6TR datasheet, STM32H533HEY6TR pinout, STM32H533HEY6TR application, or STM32H533HEY6TR equivalent, key selection criteria include TrustZone-enforced peripheral isolation, on-the-fly Octo-SPI memory decryption, 100 K-cycle data flash endurance, and dual 12-bit ADCs with 5 Msps sampling rate.

Technical Context

The device implements Armv8-M mainline security with configurable SAU regions and ST-iROT immutable root of trust. Its dual GPDMA controllers offload CPU for concurrent secure/non-secure data movement, while ART Accelerator includes 8-Kbyte instruction cache and 4-Kbyte data cache for zero-wait-state flash execution and external memory access.

Security architecture integrates SFI (Secure Firmware Installation), HUK-based secure data storage, and tamper detection. Clock system supports multiple internal oscillators (64 MHz HSI, 48 MHz HSI48, 32 kHz LSI) and external sources (4–50 MHz HSE, 32.768 kHz LSE), with dual PLLs for independent secure/non-secure domain clocking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar secure MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32H563VIT6	LQFP100 package, 100 MHz higher max CPU frequency (250 → 350 MHz), 1 Mbyte flash, 512 Kbyte RAM, adds Ethernet MAC and USB HS - larger footprint and higher power	Suitable for high-throughput gateways requiring Ethernet backhaul and richer peripheral set; not drop-in compatible due to pin count and package size	Select when needing >250 MHz performance, Ethernet, or >512 Kbyte RAM; avoid if board space or cost sensitivity favors WLCSP39
NXP LPC55S69JBD100	Cortex-M33 core, 150 MHz max, 640 Kbyte flash, 320 Kbyte RAM, no Octo-SPI, single AES accelerator, lacks PSA Level 3 certification	Lower-cost alternative for less demanding security use cases; no on-the-fly external memory decryption or dual ADC interleaving	Choose for cost-sensitive designs where PSA Level 3 and OTFDEC are not required; verify TRNG compliance against NIST SP800-90B independently

Compared with STM32H533HEY6TR, STM32H563VIT6 offers higher compute headroom and Ethernet but requires PCB redesign; LPC55S69JBD100 reduces BOM cost but sacrifices certified security assurance, external memory encryption, and ADC throughput - making it unsuitable for revenue-grade or tamper-evident applications.

What is the maximum operating frequency and DMIPS rating of the STM32H533HEY6TR?

The STM32H533HEY6TR operates at up to 250 MHz and delivers 375 DMIPS (Dhrystone 2.1). This performance is achieved with the Arm Cortex-M33 core, FPU, and ART Accelerator's 8-Kbyte instruction cache enabling zero-wait-state execution from embedded flash. The 1.5 DMIPS/MHz efficiency reflects optimized pipeline utilization and cache hit rates in real-world firmware workloads.

Does the STM32H533HEY6TR support secure boot and firmware updates?

Yes. It implements Secure Firmware Installation (SFI) with an immutable ST-iROT root of trust, verified boot chain, and hardware-protected secure hide protection area (HDP). Firmware updates are validated using public-key cryptography via the DPA-resistant PKA, and encrypted images can be stored externally and decrypted on-the-fly by OTFDEC - ensuring confidentiality and integrity throughout the update process.

What are the key analog capabilities of this MCU?

The device integrates two independent 12-bit ADCs supporting up to 5 Msps aggregate sampling rate, a dual-channel 12-bit DAC, digital temperature sensor (DTS), analog temperature sensor, voltage reference buffer (VREFBUF), and VBAT monitoring. These peripherals enable high-precision sensor acquisition, closed-loop control actuation, and system health monitoring - all with configurable TrustZone protection for secure analog data paths.

Which package type and ball count does the STM32H533HEY6TR use?

The STM32H533HEY6TR uses a 39-ball WLCSP (Wafer-Level Chip Scale Package) with 2.76 × 2.78 mm body size and 0.4 mm pitch. This ultra-compact package provides 33 GPIOs (most 5 V-tolerant), dedicated power/ground balls, and SWD debug interface - ideal for space-constrained portable and wearable electronics where PCB area and thermal profile are critical constraints.
