requires satisfying the consumer's
clamor for better safety, location
services, and infotainment. It
also requires features that will be
relevant and will stay relevant not
only when the vehicle fnally rolls
of the assembly line, but also
during its many years of use.

A recently passed law in Europe
mandates "that all new cars sold
in the EU from April 2018 must
incorporate 'eCall' tech," according
to ofcials at STMicroelectronics
( st.com ). However, "until now, the
automotive telematics industry
has used processors that were
not specifcally designed for this
purpose and therefore included
more functions—and used more
t ST's Telemaco2 family of four
application-specifc processors are
designed specifcally for automotive
telematics. They have an integrated
secure CAN subsystem to eliminate
needing a separate in-vehicle bus
controller, and they come with RSA
authentication to secure embedded
system code, as well as GNSS and
Dead Reckoning software.

needed."
The Telemaco2 family of applica-
tion-specifc processors from ST
is explicitly designed for automo-
tive telematics. This set of four
microcontrollers minimize the cost
of developing telematics applica-
tions in three ways: including
only essential Internet protocol
technology, being independent
of modem technology, and using
Linux (open-source) software
components. The four Telemaco2
chips difer in what features are
included in each chip.
The Telemaco2 processors
feature an embedded boot core
that eliminates the need for a
separate controller unit and an
integrated secure CAN (Controller
Area Network) subsystem that
eliminates the need for a separate
in-vehicle bus controller. The chips
come with RSA authentication
to secure embedded system code,
as well as Global Navigation
Satellite System (GNSS) and Dead
Reckoning software, which work
with ST's Teseo satellite-tracking/
