More than 20% of the value of each car already
comes from embedded electronics. Keeping costs and space for additional
functionality low requires further integration of electronic components such
as low and high voltage devices and memory on a single System-on-Chip (SoC).
SoC technologies for segments with lower reliability requirements are
However, there are no cost-effective technologies yet combining all of the
harshest automotive reliability requirements for full SoC integration of
powertrain ICs for engines, starters, alternators, etc. This barrier to
powertrain IC SoC integration inhibits cost reduction and introduction of
more fuel-efficient cars.
The purpose of ATHENIS is to provide proof of concept for the industry's
first SoC technology platform that can surmount these integration barriers.
The ATHENIS SoC technology platform is intended to be the first in meeting
the combination of all of the harshest requirements including full reverse
polarity capability at the low cost of CMOS, application voltages up to
120V, currents up to 10A, temperatures up to 200?C, embedded non-volatile
memory, chip-level ESD up to =8kV HBM, and high logic gate densities.

This will be achieved by combining HVCMOS technology from
austriamicrosystems AG with MEMS-based 'Nanomech' embedded Non-Volatile
Memory (eNVM) technology from Cavendish Kinetics. Innovative (patent
pending) add-on technology modules such as reverse polarity HVCMOS and =8kV
ESD structures for HVCMOS as well as automotive extensions for Nanomech will
be developed. An alternator-like demonstrator with and without eNVM is
selected for a worst-case proof of concept. eNVM will enable 'flexibility'
to software-configure alternator systems for multiple car platforms.
Valeo Electrical Systems will provide system specifications, system
development and system evaluation. The other research partners contribute
the required novel characterization, reliability, test, and simulation
