STMicroelectronics’ high-performance
microcontrollers pave the way to new innovations in smart home and
industrial systems
New STM32H7R/S microcontrollers raise
embedded-application performance to new levels for next-generation
smart devices in factories, buildings, infrastructure, eHealth
Geneva, Switzerland, March 12, 2024 – STMicroelectronics
(NYSE: STM), a global semiconductor leader serving
customers across the spectrum of electronics applications, has
revealed a new high-performance device that punches above its
weight by combining performance, scalability and security of
microprocessor-based systems that are typically more complex with
the simplicity and integration of microcontrollers (MCUs).
Using these new STM32H7 MCUs, producers of equipment like smart
appliances, smart-building controllers, industrial automation, and
personal medical devices can evolve their products more quickly and
cost effectively as end-users’ demands continue to increase.
Examples include adding richer, colorful user interfaces and
performing multiple functions simultaneously, which is usually
achieved with microprocessors (MPU).
“Our STM32 is already the world’s most popular Arm Cortex-M
microcontroller family, and the latest STM32H7 devices let
designers address even more use cases within this powerful
ecosystem,” said Patrick Aidoune, General Purpose MCU Division
General Manager, STMicroelectronics. “Its MPU-like qualities
deliver outstanding core performance with the peripheral
integration and convenience of an MCU, at a cost-effective price
point.”
“With a dedicated graphics processor and fast memory interfaces
on-chip, these MCUs are perfectly aligned with our mission to push
the boundaries of what's possible in embedded displays,” commented
Kamil Kozlowski, CEO of Riverdi, a lead customer for the STM32H7R/S
MCUs. Riverdi has chosen the devices to power its next generation
of display modules. “The MCUs promise to enhance the visual
performance and responsiveness of future displays, enabling more
engaging and interactive user experiences. This represents a
significant step forward in our journey to provide cutting-edge
display solutions to our customers.”
ST’s new STM32H7R and STM32H7S microcontrollers come with robust
security features, needed to address Internet of Things (IoT)
applications. They include protection against physical attacks,
memory protection, code isolation to protect the application at
runtime, and platform authentication. The STM32H7S devices provide
further security enhancement by integrating immutable root of
trust, debug authentication, and hardware cryptographic
accelerators that support the latest algorithms to prevent
unauthorized access to code and data. With these security features,
the devices are targeting up to SESIP3 and PSA Level 3
certifications, meeting the highest industry standards for cyber
protection.
The STM32H7 MCUs combine the highest-performing Arm® Cortex®-M
core ST has yet announced (Cortex-M7 running at up to 600MHz) with
minimal on-chip memory and high-speed external interfaces. They let
engineers build systems with extra performance and flexibility
using simple, low-cost microcontroller development tools. The
devices available are further divided into the STM32H7R3/S3
general-purpose MCUs and the STM32H7R7/S7 with enhanced
graphics-handling capabilities. Developers can share software
extensively between the two lines, enabling efficient use of
project resources and faster time to market for new products.
Michela Menting, Senior Research Director from ABI Research,
said: “IoT hardware security is the holy grail for created trusted
devices. The difficulty has been to offer a high-level of security
for MCU-based embedded hardware, while achieving MPU-performance in
a cost-effective manner; three criteria that are not often seen
together in the market. The new STM32H7 MCUs appear to offer just
that, with security front and center, built to perform the
multi-application requirements of privacy-hungry markets in the
consumer and industrial space.”
ST’s new STM32H7 MCUs are scheduled to enter volume production
from April 2024. Sample requests and pricing information are
available from local ST sales offices.
The STM32H7S8-DK demonstration and development platform, and the
affordable and extendable NUCLEO-H7S3L8 MCU board, are available to
accelerate building applications using the new devices.

Technical Notes to Editors:
ST’s strategy, with the new STM32H7 devices, is to embed
Bootflash memory and SRAM on the chip while application code and
data is stored in off-chip memory ICs. The bootflash ensures easier
and more secure startup, in keeping with STM32 MCUs, and
facilitates application development using familiar tools and STM32
software packs. The STM32Cube software and tools help developers to
set up the boot system and locate their code in external
memories.The developer is free to choose the right type and size of
external memories to fulfil the application and ensure a
cost-effective bill of materials (BoM). The application code can
either be executed from external memory or loaded into the large
internal SRAM. The I/O pins for connecting external memory ICs
embed memory crypto engines (MCE) that encrypt and decrypt coded
data on-the-fly. The memory interfaces operate at up to 200MHz in
DTR, ensuring seamless application execution.
Alongside the high-performing core, ST has integrated its
NeoChrom GPU that enables MPU-like graphical user interfaces (GUIs)
with rich colors, animation, and 3D-like effects. With the display
controller also on-chip, these MCUs can handle vibrant and colorful
high-definition user interfaces that would be too taxing for
smaller microcontrollers. Running the UI uses only about 10% of the
main CPU performance, enabling appliances to deliver
smartphone-like user experiences while also running demanding
applications like edge AI, communication, and real-time control.
The STM32H7R and STM32H7S are already supported in ST’s TouchGFX
GUI development framework, which is continually updated with new
features that let developers create imaginative effects with smooth
and fluid graphics and animations.
As MCUs, the new devices let users create simple PCB designs
that require many fewer layers than typical MPUs and so save costs.
Designers also benefit from the wide range of package options,
which extend from low-cost 68-pin packages to packages with up to
225 pins for applications that demand many external connections,
such as large numbers of sensor inputs or communication
channels.
In addition, power management is integrated on-chip, in contrast
with typical MPU practice that requires an external
power-management IC (PMIC).
