STMicroelectronics : Microcontrollers from STMicroelectronics Drive Vehicle
Safety to Highest Standards
Multi-core microcontroller using in-house embedded Flash process technology
enables functional safety compliance in automotive systems
Geneva, February 21, 2013 - 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 -safety devices.
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 system costs.
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
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
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.
