New STM32H5 MCU series from
performanceand security for
next-generation smart applications

STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, has introduced its new performance-oriented STM32H5
microcontroller (MCU) series with cutting-edge security provided by
STM32Trust TEE Security Manager for smart, connected devices.
The new STM32H5 MCUs contain the embedded core from Arm®, the
Cortex®-M33, which blends high performance with security, energy
efficiency, and affordability, to best address the mid-range class
of MCU-based applications. Indeed, it’s the world’s highest
performing Cortex-M33 implementation, running at 250MHz and 375
DMIPS for an EEMBC CoreMark® industry-reference score of 1023.
The STM32H5 series is designed to accelerate innovation at scale
for the coming generations of smart, connected devices, which
provide more intelligence “in the edge” and also strengthens
defenses against attacks on IoT assets. The Cortex-M33 core brings
Arm’s TrustZone® architecture. Building on this, ST adds a range of
its own security features, including some developed with ST
Authorized Partner, ProvenRun.
The STM32H5 is the first MCU series to come with system-on-chip
(SoC) security services accessed via an industry-standard API. This
facility, called STM32Trust TEE Secure Manager, saves developers
writing their own code while providing security services developed
according to known best practice. It simplifies development while
ensuring effective protection.
“Our connected world is ready for the enhancements coming with
the STM32H5 series, to support advanced services while keeping
users, assets, and data secure,” said Ricardo De Sa Earp, Executive
Vice President General-Purpose Microcontroller Sub-Group,
Microcontrollers and Digital ICs Group. “We expect these new MCUs
to become the preferred controllers making tomorrow’s smart homes,
factories, and cities intelligent, safe, and sustainable.”
Challenging the perception that increased performance comes with
power dissipation constraints for developers, the STM32H5 MCUs also
improve energy efficiency by leveraging ST’s advanced 40nm CMOS
process technology and improved on-chip power-conversion circuits.
With these MCUs, power dissipation is no longer a constraint when
using a 250MHz device in harsh environments where the ambient
temperature can reach 125°C. In addition, STM32H5 MCUs are
SIL-ready for products that must meet an appropriate safety
integrity level (SIL), thanks to native hardware features that
address a wide range of industrial and medical applications.
Typical applications for the new MCUs include air conditioning
systems, appliances, and alarm systems, industrial programmable
logic controllers (PLCs), motor controls, industrial pumps,
communication gateways, lighting controls, and energy conversion.
They are also used in consumer products such as PC peripherals,
smartphones, and accessories.
Further technical information:ST has worked
with highly regarded technology companies to achieve the
significant improvements in performance and security now available
with the STM32H5 series. The Company has been a lead development
partner with Arm, supporting development of the Cortex-M33 core to
comply with the PSA Certified Level 3 and GlobalPlatform SESIP3
security specifications. In addition, ST has collaborated with
Microsoft Azure on middleware with strong security.
The STM32Trust TEE Secure Manager is developed with ProvenRun
and powered by ProvenCore-M to ensure today’s highest
security-assurance levels. The SoC security services provided
include isolation, cryptography, key storage, and initial
attestation. To help users maximize its potential, ST has created
dedicated development kits NUCLEO-H503RB for $15, NUCLEO-H563ZI for
$29, and STM32H573I-DK for $99 with examples showing how to use the
security services and integrated all the necessary software tools
and support in the STM32Cube development ecosystem.
The new devices also provide in-ST factory pre-provisioning
credentials for seamless registration to various cloud and OEM
servers, multi-tenant IP protection, and remote pre-integrated 3rd
party public key infrastructure (PKI) lifecycle management.
In addition, the Kudelski IoT keySTREAM™ root of trust, from ST
Authorized Partner Kudelski IoT, was pre-qualified on the
STM32Trust TEE Secure Manager to allow remote credential lifecycle
With its improved power-conversion circuits, the STM32H5 MCUs
raise dynamic efficiency to 61µA/MHz in switched mode (SMPS) and
120µA/MHz running off the linear (LDO) converter (at VDD = 3.3V and
25°C) in Run mode with peripherals off. Consistent with other STM32
MCUs, ST’s advanced peripherals are engineered for maximum
efficiency, while precision power management lets developers
optimize performance versus power consumption in all operating
The product lines initially available include the STM32H503
product line with128KB Flash, allowing 250MHz computing capability
in space- and cost-constrained applications. Also, the STM32H562
and STM32H563 product lines have up to 2MB Flash, rich
connectivity, and deliver 250MHz over the extended temperature
range up to 125°C. The STM32H573 includes AES cryptographic
acceleration and security services.
Prices at 10,000 units for the new MCUs start at $1.44 with
128KB Flash in UFQFPN32 package. Devices with 2MB Flash size are
priced from $2.93. Mass production is beginning now, starting with
the STM32H503 and STM32H563. The full lineup and package choices
will be introduced in June.
