TDA7500A

2/40

DESCRIPTION (continued)

An I

able to interface the display micro.The DSP cores are integrated with their associated data and program mem-

ories. The peripherals and interfaces I

Interface, (EMI), General Purpose I/O register (Port A) and the D/A registers are connected to and controlled by

DSP0, whereas the A/D registers, the SPDIF and the General Purpose I/O register (Port B) are connected to

and controlled by DSP1. An hardware RDS filter , demodulator and decoder block is also embedded. No support

is needed from the DSPs but at initialisation so that RDS can work in background and in parallel with other DSP

processing. Separated Debug and Test Interfaces are connected to both DSP cores.

The TDA7500A is supposed to be used in kit with the TDA7501 or any other device of the same family. Thanks

to the serial audio interface also digital sources can be processed and a direct output to a digital bus is also

available.

The flexibility allowed by the wide memory space and by the two powerfull DSP cores make the TDA7500A us-

able for different applications. In example, inside the main radio as an audio co-processor or to perform the sig-

nal processing and equalisation associated to a digital power amplifier.

ABSOLUTE MAXIMUM RATINGS

Warning: Operation at or beyond these limit may result in permanent damage to the device. Normal operation is not guaranteed at these

extremes.
