sensitivity. The simultaneous HDR and LFM capability
is especially important in enhancing safety as it ensures
that all objects and potential hazards can be identified
in both very dark and very bright areas of the scene.
With the widespread use of LEDs for front and rear
lighting as well as traffic signs, the LFM capability of the
platform makes certain that pulsed light sources do not
appear to flicker, which can lead to driver distraction or,
in the case of front facing ADAS, the misinterpretation
of a scene by machine vision algorithms.
The Hayabusa product family also features real-time,
ISO26262-compliant functional safety capabilities to
alert the system processor if the sensor has any issues
or potential errors. These features enable system
designs rated up to ASIL-C. The real-time capability
enables errors to be identified immediately rather
than waiting for the full image to be transferred to the
processor and then waiting for image analysis. This
faster response time means the system processor can
take immediate action to remedy the issue, which is
crucial when considering that a vehicle moving on a
freeway easily covers 100 feet in less than one second.
The first product in this family, the 2.6 megapixel (MP)
AR0233 CMOS image sensor, is capable of running
at 60 fps while simultaneously delivering ultra-high
dynamic range and LED flicker mitigation along with
all of the Hayabusa platform features. Samples are
available now to early access customers. Contact

STMicroelectronics’ Advanced
Automotive Processors with Built-In Security
Set to Protect Connected Cars against Cyber
Threats
STMicroelectronics, a global semiconductor leader
serving customers across the spectrum of electronics
applications, is leading the race to protect connected
cars against cyber threats with its latest automotive
processors that feature a dedicated, built-in security
module.
Millions of connected cars are already on the road, and
industry analysts predict there will be more than 250
million by 2020[1]. Connected services supported by
on-board telematics units, Wi-Fi hotspots, Bluetooth
®
devices – and aftermarket equipment such as on-
board diagnostics (OBD) dongles - enable drivers
and passengers to be safer, more productive, socially
connected, and better entertained on their journeys.
Unfortunately, all this connectivity builds a real surface
of attack for hackers.
Automotive groups are quickly addressing security
measures to support growth in valuable markets
for connected services such as content streaming,
location-based assistance, intelligent emergency
support, and remote software updates over the air of
in-car electronic control units (ECU), while preventing
hackers exploiting the connections for their own ends.
Experts recommend manufacturers employ a range of
techniques, including establishing trust in connected
devices and securing all connections, to provide
multiple layers of defense throughout the vehicle’s
circuitry and software.
ST is helping the industry meet these challenges by
combining its expertise in security chips – proven in
financial and government applications worldwide —
and automotive semiconductors that meet important
industry safety and quality standards. The new
Telemaco3Ptelematics and connectivity processors
(STA1385 and its variants) are the first automotive
microprocessors to integrate a powerful, dedicated,
isolated Hardware Security Module (HSM), which
acts like an independent security guard to watch data
exchanges and encrypt and authenticate messages.
The HSM securely checks the authenticity of received
messages and any external devices that try to connect
and protects against eavesdropping.
With this HSM on-chip, Telemaco3P devices are ahead
of the general-purpose application processors typically
found in current connected-car systems, which lack
dedicated hardware-based security. ST’s new chips
are also extremely robust, with a 105°C maximum
temperature rating for use in locations that can become
extremely hot, such as on top or directly beneath the
roof in a smart antenna.
