Microcontrollers From STMicroelectronics Drive Vehicle Safety to Highest
Multi-Core Microcontroller Using In-House Embedded Flash Process
Technology Enables Functional Safety Compliance in Automotive Systems
GENEVA -- (Marketwire) -- 02/21/13 -- STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the
spectrum of electronics applications and a top supplier to the
automotive industry, today announced a new member in its multi-core
microcontroller (MCU) family aimed at functional safety applications
for car electronics. The new device combines compliance with the most
stringent automotive safety standards (ISO 26262) and increased
non-volatile memory size, giving a simple upward migration path from
existing parts and strengthening ST's product line of fault-tolerant
microcontrollers for mission-critical automotive applications.
The SPC56EL70 32-bit microcontroller is the newest member in ST's
product line designed to cover a wide range of automotive
applications that need to respect the automotive safety integrity
levels (ASIL) that are now required, up to and including the most
stringent ASIL D level. These requirements are now commonplace in
critical systems such as anti-lock braking, electric power steering,
active suspension and advanced driver assistance systems (ADAS).
The ISO 26262 functional safety standard defines the rules needed in
order to avoid unreasonable risk due to hazards caused by
malfunctioning of the complete electrical system. The
microcontroller's role is extremely critical so all sections of the
standard that are applicable have been evaluated for ST's automotive
ST's new single-chip automotive microcontroller combines two
high-performance cores with 2MB Flash and 192kB internal RAM memory,
three CAN (Controller Area Network) interfaces and an optimized
peripheral set for safety and motor-control applications, supporting
up to two brushless 3-phase motors. The dual-core architecture
reduces duplication of components at a system level, lowering overall
The architecture also provides unique flexibility by allowing the
user to select lockstep or dual parallel processing (independent core
operation) modes, enabling support of multiple safety architectures
that the user can configure to achieve the required balance between
safety and performance level.
The SPC56EL automotive microcontroller product line is part of the
family of Power Architecture(TM) devices enabling integrators to use
the 32-bit MCU core throughout powertrain, car body, chassis and
safety systems. These devices support advanced functions, enable
improved vehicle performance and economy, and deliver savings in
development by promoting hardware and software reuse.
All the devices combine the scalable e200-core 32-bit Power
Architecture with an application-optimized peripheral set and
plentiful embedded Flash memory, to increase integration, maximize
design reuse, shorten time to market, and reduce costs.
As part of the complete supply-chain strategy, this product line is
manufactured in ST's in house embedded Flash (eFlash) process
technology, which builds upon the Company's 20-year expertise in
embedded Flash. The SPC56EL product line has an available memory
range from 768 Kbytes to 2 Mbytes of Flash and is currently available
in LQFP100 and LQFP144 package configurations. BGA257 versions are
also planned in the near future.
"Functional Safety Compliance is essential to realize cutting-edge
System-on-Chip ICs for mission-critical automotive applications,"
said Fabio Marchio, Group Vice President, General Manager of ST's
Automotive Microcontroller & Infotainment Division. "Offering an
upward migration path with increased memory while keeping
compatibility with already established dual-core devices enables our
automotive customers to rapidly address more demanding applications
such as in radar applications, as they evolve from producing warnings
to taking action."
Compliant with the ISO 26262 ASIL-D standard, the SPC56EL70 is
sampling now. For further information, including pricing, please
