package, giving automotive designers twice the freedom
to miniaturize ECUs deployed in the most extreme
temperature environments and safety-critical systems.
The LM2904WHYST dual op amp and LM2903WHYST
dual comparator in 4.9mm x 3.0mm MiniSO8 are
qualified for operation from -40°C to 150°C, with the
added advantage of 50% smaller footprint than other
Grade-0 parts in standard SO8.
The extremely wide ambient operating temperature range
of these ICs ensures robust and resilient performance
in systems that are exposed to the harshest conditions.
These include under-the-hood electronics such as engine
controllers, in-gearbox modules, LED-lighting controllers
and safety-critical systems such as ABS controllers that
must provide absolute dependability.
The new parts are developed with the benefit of ST’s
extensive experience working withmajor automotive Tier-
1 suppliers, and can be individually tested up to 150°C
as part of Production Part Approval Process (PPAP)
tests. As high-quality industry-standard LM2903 and
LM2904 devices, they deliver benchmark performance
compared to familiar metrics including input bias current,
input offset voltage, current consumption, and supply-
voltage range.
The LM2904WHYST and LM2903WHYST are in
production now, priced from $0.51 for orders of 1000
pieces..
NI Releases HIL Software Geared to
Autonomous Vehicle Testing
NI (Nasdaq: NATI), the provider of platform-based systems
that enable engineers and scientists to solve the world’s
greatest engineering challenges, today released VeriStand
2016, the latest version of its software used by embedded
software test engineers to build and run hardware-in-the-
loop (HIL) verification systems. Today’s engineers face
increasingly compressed, shifting schedules and constantly
changing requirements driven by the emergence of the
connected car and autonomous vehicles. VeriStand and
NI’s HIL systems are the most open and customizable
platforms available on the market to help companies
meet these changing demands and future-proof their test
systems.
Engineers take advantage of NI’s HIL systems to tackle
the increasing complexity of embedded software and
rising number of testing scenarios required as the newer
technologies that make up next-generation vehicles
like advanced driver assistance systems (ADAS),
automotive radar and vehicle-to-everything (V2X) become
commonplace in embedded control systems. By building
on open and proven technology software and hardware
platforms, NI can quickly add native support for these new
technologies to ensure customers can achieve complete
software test coverage.
Additionally, with NI offices in 49 countries and a worldwide
network of NI Alliance Partners with vertical industry and
systems integration experience, turnkey test systems that
meet customers’ particular application requirements can
be delivered and supported.
“Through NI’s flexible platform-based approach, we could
easily customize the HIL system to integrate specific test
requirements for the vehicle electronic controllers,” said
Zhang Fuli of Beijing Jingwei HiRain Technologies, an NI
Alliance Partner. “The NI software and hardware systems
made it easy to add functionality to our tests and satisfy
the practical requirements of automotive HIL testing while
retaining stability and reliability, and reducing the overall
development cycle.”
VeriStand is the software core of NI’s HIL systems.
It combines real-time simulation, data acquisition,
communication protocols and control into a common
platform for the most complete HIL test software on the
market today. And unlike traditional HIL software that is
defined by the vendor and hard to modify, VeriStand can
easily be extended and customized to meet customers’
particular test requirements. With the newest release of the
software customers can:
Achieve complete test coverage by taking advantage of
the full breadth of NI I/O, including RF and camera
processing
Use their models from over 30 different modeling tool
and simulation environments such as The MathWorks, Inc.
