Leading supplier of
semiconductor solutions for car infotainment, STMicroelectronics Pty Ltd announces
the launch of a new generation of processors for car radio and display audio applications.
Building on the success of the
popular STA1052 audio System-on-Chip, the new Accordo2 family of automotive
audio processors offers a high level of hardware and software integration, helping
to reduce the design cycle and enable fast time-to-market solutions.
The Accordo2 family offers a
fully integrated audio subsystem, including media decoding, audio routing,
sound processing, and analogue audio inputs and outputs, as well as an
independent secure CAN (Controller Area Network) microcontroller subsystem. Car
infotainment manufacturers have been using multiple devices to achieve the same
result delivered by a single Accordo2 device today.
ST’s Accordo2 devices deliver
several advantages to car infotainment manufacturers including minimising the
customer’s bill of materials (BoM); facilitating faster product development thanks
to a complete turnkey software solution that includes middleware, media
players, audio codecs, and sound-effect processing; and application scalability
to design a basic car radio all the way up to connected car radio and display audio
applications, while reducing engineering costs by reusing the same hardware and
software architectures for all use-case scenarios.
According to Antonio Radaelli,
Infotainment Business Unit Director, STMicroelectronics, the Accordo2 family
offers a platform for customers to develop their own unique products with the
lowest BoM and in the shortest time, with the built-in hardware and software
integration enabling them to quickly and easily create their own branded
products using the reference designs.
Accordo2 devices include a
32-bit ARM Cortex R4 core, running at up to 600MHz to handle all media
management, connectivity, and audio-decoding functions. The flagship product
(STA1095) incorporates an additional ARM Cortex M3 controller dedicated to
real-time CAN/Vehicle Interface Processing and a powerful Digital Signal
Processor (DSP) that supports sound-enhancing algorithms in addition to
offering Echo Noise Cancellation (ECNR) for Bluetooth hands-free phone calls.
All Accordo2 devices are housed
in LFBGA 361-ball (16 x16 x1.7mm, 0.8mm pitch) packages.
