Geneva, September 1,
2022 –
STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of
electronics applications, has unveiled new microcontrollers (MCUs)
targeting the coming electrified drivetrains and domain-oriented,
over-the-air updateable systems that are the foundation of the next
generation of EVs. As the vehicles generate, process, and transfer
large data flows, especially to support the next generation of EVs,
ST’s new Stellar P automotive MCUs are the industry’s first
qualifiable devices for model year 2024 vehicles to integrate the
new CAN-XL in-car communication standard. This technology enables
the new vehicle platforms to handle growing data flows so the car
can operate at peak performance.
“The real-time, power-efficient Stellar P6 automotive
microcontrollers combine advanced integration of motion-control and
energy-management domains with actuation capabilities, ensuring a
smooth shift from traditional ICEs/EVs to new drive-traction
architectural patterns of software-defined vehicles,” said Luca
Rodeschini, Automotive and Discrete Vice President, Strategic
Business Development and Automotive Processing and RF General
Manager, STMicroelectronics. “As the automotive industry begins
work on new vehicle platforms for model-year 2024, ST is ready with
the microcontrollers to support development and ease the transition
to vehicle production.”
ST’s Stellar family of automotive MCUs has been designed to
support carmakers and Tier1s as they transition toward
software-defined vehicles. Stellar now includes multiple
series:
- Stellar E series assures fast real-time control and system
miniaturization in power-conversion applications, maximizing the
benefits of SiC and GaN power technology in EVs’ on-board charging,
DC-DC converters, and traction inverters, among other
applications.
- Stellar G series MCUs act as a secure data HUB and real-time,
safe aggregator of functions within the body domain primarily for
zonal architectures.
This series implements best-in-class OTA updates, low-power
modes, and data routing over a broad set of in-car communication
protocols.
- The new Stellar P series of automotive MCUs offers qualifiable
devices that combine advanced actuation capabilities with powerful
function integration. Stellar P devices target the new drivetrain
trends for electric vehicles and domain-oriented architectures, for
the best real-time performance and energy management.
Samples of Stellar P6 are available now for model-year 2024
vehicles. Contact your local ST Sales office for pricing options
and sample requests.
Additional information
Carmakers are transitioning to software-defined vehicles for
their next-generation vehicle platforms to manage the complexity
and performance of the new features they are adding to vehicles
(electrification, advanced safety, assisted and automated driving).
This transition requires top to bottom revamping of the car
platform’s architecture. The key changes include moving from many
electrical control units (ECUs) that each manage a small subsystem
to domain or zone controllers that combine multiple functions.
These controllers must also manage the consolidation of software
from across a range of vehicle systems. Safety and performance is
assured by the new generation of automotive-grade MCUs like Stellar
that enable greater processing performance and integration of key
functionalities. In software-defined vehicles fully driven by
electronics systems, Stellar delivers fully synchronized operations
and secure over-the-air software upgrades of all systems for both
maintenance and continued performance improvement.
Technical information
Manufactured in ST’s own wafer fabs using power-efficient 28nm
FD-SOI technology, the Stellar P6 embeds up to 20 Mbytes of Phase
Change (non-volatile) Memory (PCM). Developed and tested according
to stringent automotive requirements for high-temperature
operation, radiation hardening, and data retention, ST’s PCM also
delivers faster access time through single-bit overwrite, a feature
unavailable in Flash. In addition, over-the-air updates with no
downtime leverage a game-changing mechanism that saves memory by
dynamically allocating memory space to the new downloaded software
image until it is validated. This happens while the rest of the
memory continues to execute the running application in
real-time.
ST’s Stellar P6 MCUs contain up to six Arm® Cortex® R52
processor cores, some operating in lockstep and some in split-lock
mode to provide failsafe redundancy. These enable the new devices
to deliver high performance, real-time determinism, and
upgradeability for next-generation automotive drivetrains,
electrification solutions, and domain-oriented systems. Stellar P6
manages hardware virtualization (sandboxing) using the Cortex-R52
features and firewalls to resource access. This simplifies the
development and integration of multiple-source software on the same
chip while ensuring safe isolation and performance.
State-of-the-art safety measures at all levels of the
architecture ensure the most efficient implementation of ISO 26262
ASIL-D functions. In addition, the FD-SOI technology inherently
offers a quasi-immunity to radiation and provides superior
protection against system unavailability while ensuring compliance
with the most stringent safety standards.
A fast hardware security module (HSM), extended with
cryptographic engines operating in lockstep, supports secure ASIL D
functions and enables enhanced EVITA full security capability. It
also provides high-speed security cryptographic services and safe
network authentication to further protect manufacturer firmware as
well as end-users’ data.
