Presented as a new generation of processors for car-radio and display-audio applications, and developed from the STA1052 audio system-on-chip, the Accordo2 family (STA1095 and variations) offers hardware and software integration for fastest time-to-market. 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. Until now, car infotainment manufacturers had to use multiple devices to achieve the same result.
In addition to minimising bill of materials, Accordo2 allows faster product development as it comes, with a complete turnkey software solution that includes middleware, media players, audio codecs, and sound-effect processing. The various members of the family offer 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.
Accordo2 devices include a 32-bit ARM Cortex R4 core, running at up to 600 MHz, 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, as well as a DSP that supports sound-enhancing algorithms as well as echo noise cancellation (ECNR) for Bluetooth hands-free phone calls.
All Accordo2 devices are housed in LFBGA 361-ball (16 x 16 x 1.7 mm, 0.8 mm pitch) packages.
