STA1080, STA1085, STA1090, STA1095 Description

1 Description

Accordo2 is a family of devices that provide a cost effective microprocessor solution for

modern automotive car radio systems, with an embedded powerful Digital Sound

Processing subsystem, as well as a MIPS efficient ARM Cortex-R4 processor.

In addition, an ARM Cortex-M3 controller is dedicated for real-time CAN / Vehicle Interface

Processing.

In terms of peripherals, Accordo2 family devices come with an exhaustive set of common

interfaces (UART/I2S/I2C/USB/MMC) which make the device optimal for implementing a

feature rich system as well as a cost effective solution.

The solution is bundled with a complete software package, which allows a very fast system

implementation.

Accordo2 family devices manage the entire audio chain from analog or digital inputs to

analog or digital outputs, including digital audio media decoding, sample rate conversion

among various sources, intelligent routing and audio effects / DSP post processing. With its

flexible memory configuration, it allows implementing from very low cost systems based on

real time OS, scaling up to demanding applications based on Linux OS.
