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
http://www.st.com/internet/automotive/subclass/963.jsp  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 http://www.st.com/web/catalog/sense_power/FM2098/SC963/SS1534/PF252000  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 level.

The SPC56EL http://www.st.com/web/catalog/sense_power/FM2098/SC963/SS1534/PF252000  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
http://www.st.com/web/catalog/sense_power/FM2098/SC963/SS1534/PF252000  is sampling now. For
further information, including pricing, please contact your ST sales office.
