Microcontroller Solutions Group
Body Green Network Demo
Description
The increasing demand for new safety and
comfort features in today's automobiles
results in a significant increase in the
complexity of onboard systems. This leads
to a rise of power consumption as well as
an increase in automotive weight and fuel

advanced low-power modes. Our body green
network demo shows the ability of Freescale
devices to significantly reduce the power
• One MPC5517-based body controller unit
with CAN/LIN gateway functionality
• Three MM912F634S-based LIN slave units
consumption of onboard systems by using
(motor control application, LED board, light/
the low-power modes of the microcontroller
temperature sensor unit)
(MCU) and system basis chip (SBC).
Our broad portfolio of automotive
microcontrollers, integrated circuits and
sensors solutions, plus our growing
enablement and technical support, helps you
get back on track. We enable you to create
the next breakthrough automotive designs
for powertrain, body, chassis and safety,
infotainment and telematics, and in-vehicle
networking applications.
