The automotive industry is changing rapidly to address complex challenges,
including higher bandwidth networks, improving data security, implementing
functional safety and reducing overall energy consumption. Freescale
Semiconductor (NYSE: FSL) is expanding its Qorivva and S12 MagniV vehicle body
network microcontroller (MCU) portfolios to address these challenges and bring
a new level of integration and function to automotive body applications.

microcontroller portfolios to address auto body challenges and bring a new
level of integration and function to auto body applications. Freescale's new

complementary technologies with the Qorivva central controller acting as the
networking gatekeeper with centralized data security, intelligent power
management and ASIL support for functional safety, and the S12 MagniV
satellite nodes having integrated power supplies and communications
transceivers embedded onto smart mixed-signal MCUs. (Photo: Business Wire)

As the number of electronic control units in a vehicle grows, the amount of
connectivity needed also increases. The average vehicle includes several miles
of copper wire – weighing up to 150 lbs. or more – for in-vehicle networking.
Integrating more functionality within the vehicle’s main ECUs and increasing
the intelligence of its satellite nodes (i.e. modules in doors or electric
motors) can help reduce the number of ECUs and the amount of associated wiring
required, eliminating weight in the vehicle wiring harness and helping improve
vehicle fuel economy.

Along with the demand for greener cars, there is a major push for compliance
with the ISO 26262 functional safety standard for automotive body modules,
given the critical nature of the functions they enable such as exterior
lighting and wind shield wipers. And as wireless communication to and from the
vehicle becomes more prevalent, there is a growing need for security measures
within automotive microcontrollers – to safeguard the intellectual property
they contain and also prevent unauthorized and potentially dangerous access to
the vehicle network.

Freescale’s new Qorivva MPC5748G and S12 MagniV S12ZVL/S12ZVC MCUs are
complementary technologies with the Qorivva central controller acting as the
networking gatekeeper with centralized data security, intelligent power
management and ASIL support for functional safety, and the S12 MagniV
satellite nodes having integrated power supplies and communications
transceivers embedded onto smart mixed-signal MCUs. The level of
hyper-integration these devices provide can help simplify vehicle network
design, yielding reduced weight, increased manufacturing efficiency and
reduced board sizes up to 30 percent.

“Vehicles are transforming into smart consumer devices where all connections
lead to the outside world,” said Ray Cornyn, vice president of Automotive
Microcontroller Products at Freescale. “By bringing increased intelligence to
the central communications controller in the vehicle, Freescale understands
the importance of not only securing in-vehicle networks, but also reducing
electrical and mechanical energy consumption. Our latest MCU offerings will
enable OEMs to reduce up to 20 pounds of copper wiring and board components,
reducing vehicle weight and in turn further improving fuel economy.”

Qorivva MPC5748G MCU

The Qorivva MPC5748G MCU is a single-chip solution for next-generation central
body control and gateway applications. It combines an exceptional level of
integration with innovative low-power management modes, support for functional
safety and robust security features.

The MPC5748G MCU provides one of the most diverse sets of networking
communications peripherals on the market, with support for Ethernet with Audio
Video Bridging (AVB), FlexRay™, Media Local Bus (MLB), USB, CAN FD (Flexible
Data Rate) and up to 18 LIN controllers. High performance through a multicore
architecture and memory options up to 6 MB of flash and 768 KB of RAM help
ensure efficient transfer of data and eliminate communication bottlenecks.

Central body control modules spend significant portions of time in a low-power
monitoring state. The MPC5748G features a low-power unit (LPU) mode that
allows for increased functionality in a lower-power state, cutting peak
current consumption for cyclic wakeup use cases by nearly 30 percent compared
to previous-generation devices. In addition, inclusion of analog comparators
that operate out of STANDBY mode and pretended networking help support
next-generation power budget requirements.

The MPC5748G is a Freescale SafeAssure functional safety solution, defined and
developed from the ground up to address the ISO 26262 standard. Built-in
safety functions such as self testing and end-to-end error correction coding
(ECC), comprehensive auto safety software including AUTOSAR OS and MCAL
drivers and extensive safety documentation help target the use of the device
for ASIL B.

The MPC5748G offers a hardware security module (HSM) for data protection and
ensures secure communication and flash updates through AES cryptographic
algorithms, secure memory and secure boot capabilities.

S12 MagniV S12ZVL/S12ZVC MCUs

Increasing the intelligence of CAN termination nodes or LIN nodes using the
highly integrated S12 MagniV S12ZVL/S12ZVC MCUs will help automotive OEMs
optimize their total body networking systems. The S12ZVL/S12ZVC devices allow
designers to achieve the smallest possible CAN termination nodes (using
S12ZVC) or LIN nodes (using S12ZVL) and help reduce printed circuit board
sizes by as much as 30 percent. Car systems can connect high-voltage signals
and power supplies directly to the S12 MagniV MCU, helping save additional
discrete components, increasing system quality and reducing system design and
manufacturing complexity.

The S12 MagniV portfolio enables body electronics platform design scalability
across multiple applications, with CAN and LIN connectivity options, flash
memory from 8 KB to 192 KB and a range of package options between 32 and 64
pins.

The S12 MagniV S12ZVL/S12ZVC MCUs are the first devices from the Freescale
16-bit automotive MCU portfolio included in Freescale’s SafeAssure functional
safety program. They have been defined and developed from the ground up to
address the ISO 26262 standard.
