STMicroelectronics Raises Performance and
Value for Smart, Connected Devices with Even Faster STM32H7
Microcontrollers
- Industry’s first Arm Cortex-M7-core, embedded-Flash MCUs
running at 550 MHz core speed
- Scalable architecture with state-of-the-art cyber
protection
- Feature-rich and functional-safety ready
Geneva, September 29, 2020 – STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers
across the spectrum of electronics applications, has revealed
record-breaking STM32* microcontrollers (MCUs) with embedded Flash
that bring high-end features such as rich graphics, AI, and
state-of-the-art cyber-protection to cost-sensitive new products.
The new STM32H7 MCUs build on the Arm® Cortex®-M7 core and operate
at 550 MHz, the fastest core speed in the market among MCUs that
integrate Flash storage on-chip to run deeply embedded
applications. These single-core devices, which are available with
up to 1 Mbyte of Flash, deliver increased performance with
affordability for cost-conscious applications. At the same time,
the devices can interact with off-chip storage while ensuring full
execution performance and security. Their benchmark performance
figures of 2778 CoreMark®1 and 1177 DMIPS are realized whether
working from internal or external memory, aided by features such as
the Flexible Memory Controller (FMC) and Octal SPI memory
interface. This lets designers tackle memory-hungry applications,
such as high-resolution, full-color graphics and video that demand
a large frame buffer, to create new products that deliver more
sophisticated and immersive user experiences. Further assisting the
creation of full-color user interfaces, the TouchGFX graphic
framework STM32Cube Expansion Package (X-CUBE-TOUCHGFX) and
TouchGFX Designer programming tool are available free of charge.
Advanced features powered by AI technology can be developed thanks
to STM32Cube ecosystem and STM32Cube.AI (X-CUBE-AI) to port neural
networks and leverage computer vision through the parallel camera
interface. By connecting the STM32H7 to one or multiple sensors,
condition monitoring and other machine learning techniques will
also help bringing added value to the STM32-based product. As part
of the STM32Trust security suite, cyber-protection is enhanced with
support for on-the-fly decryption (OTFDEC) and secure firmware
install (SFI). OTFDEC enables encrypted code to be executed from
external memory. SFI lets OEMs order standard products anywhere in
the world, to be programmed only with encrypted code. These two
solutions effectively safeguard OEM intellectual property in Flash
memory. Out-of-the-box security features include support for secure
boot, symmetric (by hardware or software library) encryption, and
cryptographic key provisioning. Asymmetric encryption (by software
library) is also available. Cryptographic processing is handled
with a true random number generator, hardware acceleration for
AES-128, AES-192 and AES-256 encryption, and support for GCM and
CCM2, Triple DES, and hash (MD5, SHA-1 and SHA-2) algorithms. “Our
latest STM32H7 MCUs enable small, low-power products to deliver
extraordinary functionality and performance, while leveraging the
outstanding value and efficiency of the STM32 family,” said Ricardo
de Sa Earp, Group Vice President, Microcontroller Division General
Manager, STMicroelectronics. “Home appliances, small medical
devices, and industrial sensors and actuators that might previously
have been unable to incorporate computationally intensive features
such as AI, graphics, and voice interaction now have an appropriate
solution.” Several key features deliver important advantages in
industrial applications, including an integrated switched-mode
power supply (SMPS) that overcomes dissipation constraints to allow
extended-temperature operation up to 125°C. In addition,
fault-resilience is provided through error correction (ECC) for all
memories. ST has updated the STM32 development ecosystem to let
users get started quickly with the new devices. Flexible
prototyping and demonstrations can leverage the STM32H735G-DK
Discovery kit, while the NUCLEO-H723ZG Nucleo-144 board provides an
affordable option for quickly building prototypes and
proof-of-concept models. The latest STM32H7 MCUs are also supported
in the STM32Cube ecosystem, which comprises tools, embedded
software, and middleware including graphics libraries,
communication stacks, and application-code examples such as motor
control, AI, and advanced security. The MCUs’ capabilities can also
be exercised using appropriate software tools for application and
security development published by Arm® Keil and IAR Systems. Haydn
Povey, General Manager Embedded Security Solutions, IAR Systems,
commented: “ST’s latest STM32H7 MCUs deliver game-changing value,
performance and security enhancements. The security features,
including enhanced cryptographic accelerators, advanced off-chip
memory protection, and secure key provisioning are all critical
capabilities in achieving legislative requirements, including the
recent EN303645 standard. We expect IAR Embedded Workbench, coupled
with C-Trust for security, to be the IDE of choice for engineers to
realize their full potential in next-generation designs.” The new
STM32H7 devices introduced are the STM32H723/733, STM32H725/735,
and STM32H730 Value-Line MCUs, which are available in various
package options. Prices start from $2.83 for the STM32H730VBT6, for
orders of 10,000 pieces. * STM32 is a registered and/or

Further technical information:Each of the new
devices is based on the Arm Cortex-M7 core running at the
record-breaking frequency of 550 MHz and features single-core
architecture to deliver cost-effective advanced performance.
Further features that let designers maximize performance, energy
efficiency, and flexibility in diverse applications include:
- 32 Kbytes I-cache and D-cache sizes
- Tightly coupled instruction RAM (ITCRAM) with remapping for
zero latency in time-critical routines
- ST’s proven FMAC (filtering) and Cordic (trigonometric) blocks
for mathematical acceleration
- Crypto algorithms supported
- Advanced analog peripherals including two 16-bit ADCs and one
12-bit ADC in the low-power domain
- Interfaces to popular industrial connectivity standards,
including three FD-CAN ports, Ethernet, and Parallel Synchronous
Slave Interface (PSSI)
