- New STM32H7 series establishes bar-setting industry benchmark
for ARM® Cortex®-M core performance
- Extremely high on-chip memory density and richest connectivity
peripheral set, plus state-of-the-art security for connected
objects
STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of
electronic applications, is paving the way to even more intelligent
smart devices everywhere with its new record-breaking STM32H7
series of microcontrollers, which embeds the highest SRAM memory
(1Mbytes), Flash memory up to 2MB, and the richest connectivity
peripheral set ever seen in the STM32 platform.
Central to this leap in capability is ST's own highly advanced
40nm chip-fabrication process combined with innovations in the
product architecture, unleashing the performance of the core and
enabling ultra-fast data transfers through the system while
consuming less than 280uA/MHz in run mode and less than 7uA in
stand-by. The first device in the new series is the STM32H743,
which features the ARM® Cortex®-M7 core running at 400MHz. This MCU
is the highest-performing implementation of ARM's
highest-performing Cortex-M core currently in the market. The
STM32H7 microcontrollers are perfect for industrial gateways, home
automation, telecom equipment and smart consumer products, as well
as high-performance motor controls, domestic appliances, and small
devices with rich user interfaces. Integrated state-of-the-art
security features, including cryptographic accelerators and
provision for secure-key storage, provide connected objects with a
high level of protection against online threats both during the
manufacturing and in the field; perfect for Internet of Things
(IoT) appliances.
"The diversity of IoT and embedded applications demands scalable
MCU solutions," said James McNiven, general manager for CPU and
media processing groups, ARM. "The advanced capabilities of the H7
series will enable developers to address the high end of the
embedded market while delivering all of the efficiency and
ease-of-use benefits of an ARM Cortex-M based device. With the ARM
mbed(TM) OS technology supported on the Cortex-M7, developers can
have easy access to advanced software stacks for fast
development."
Michel Buffa, General Manager, Microcontroller Division,
STMicroelectronics, added, "In addition to its industry-leading
execution performance, the STM32H7 series also significantly
increases on-chip resources while realizing power savings that are
vital for future generations of embedded systems and offering
top-notch protection from threats and intrusions. The dramatically
increased memory density, in particular, eliminates traditional
constraints on developers and so accelerates time to market for
exciting new products."
Further technical information:
The STM32H7 series features the ARM Cortex-M7 core that also
powers the STM32F7 series. The new STM32H7 series is the industry's
first Cortex-M7 fabricated on the advanced 40nm Flash process and
the first to run at 400MHz. These important enhancements enable the
STM32H743 to set new performance records of 856DMIPS[1] and an
EEMBC® CoreMark® [2] score of 2010.
ST's 40nm geometry is a key factor enabling the leap in memory
density, as it allows the STM32H743 to integrate 2MB of dual-bank
Flash with a huge 1MB SRAM that frees developers from the resource
constraints that typically complicate high-end embedded
development. The STM32H743 interacts efficiently with either
internal or external memory, thanks to its unique L1 cache and TCM
memory. These freedoms allow applications to become more
sophisticated and feature-rich, while also saving the engineering
time and effort traditionally needed to implement the specified
functionality within extremely limited resources. With the launch
of the STM32H7 series, ST is also introducing a new generation of
STM32 on-chip peripheral functions. The first device in the new
series, the STM32H743, draws on a pool of 35 communication
peripherals that support advanced protocols and standards such as
CAN FD, SDCARD (4.1), SDIO (4.0), and MMC (5.0). There are also 11
enhanced analog functions including low-power 14-bit ADCs running
at up to 2Msample/s, 12-bit DACs and op-amps, as well as 22 timers,
which include a high-resolution timer running at 400MHz.
As well as dramatically increasing the performance and
resources, the STM32H7 MCU series also incorporates STM32 Dynamic
EfficiencyTM energy-saving techniques that help the new devices
consume half the dynamic power of their predecessors in the STM32F7
series. Central to this leap in energy efficiency is ST's own
highly advanced 40nm chip-fabrication process that, in combination
with innovations in the Company's Dynamic Efficiency technologies,
allows precise optimization of power consumption. These
optimizations include Dynamic Voltage Scaling that adjusts power
consumption according to performance demands, and Batch-Acquisition
Mode that captures data directly into memory without waking the
core from energy-saving mode. ST has also created multiple memory
domains that support Dynamic Efficiency energy management. D1, D2,
and D3 domains are dedicated respectively to processing-intensive
tasks and peripherals interconnected through a high-performance AXI
bus matrix (D1 domain) as well as connectivity tasks (D2 domain),
and the energy-saving Batch Acquisition Mode (D3 domain). Each
domain can be powered on or off independently to maximize energy
savings, and can be reactivated by programmable events.
While making the updated peripherals available, ST is
maintaining the proven convenience of complete pin, peripheral, and
software compatibility among microcontrollers throughout the
STM32F4 and F7 product series. This cross-compatibility greatly
simplifies scaling of applications and leveraging design expertise
and proven code across multiple projects.
Design enablement is already well developed for ST's Cortex-M7
microcontrollers, the STM32F7 series. Evaluation boards, Nucleo
kits and Discovery kits will all be offered for the STM32H7 series,
along with STM32Cube embedded software, and will be supported by
ARM mbed OS to take advantage of advanced software stacks available
to all developers.
Six packages ranging from LQFP100 to TFBGA240 are sampling now.
The STM32H743VGT6 with 1MB Flash and 1MB SRAM in a 100-pin LQPF100
package starts at budgetary pricing of $8.17 for orders of 10,000
pieces.
The STM32H743 and further STM32H7 product lines will be in full
production in Q2 2017.
