Description

The TDA7500 is an integrated circuit implementing a fully digital, integrated and advanced solution to perform the signal processing in front of the power amplifier and behind the AM/FM tuner or any other audio sources. The chip integrates two 43 MIPs DSP cores: one for stereo decoding, noise blanking, weak signal processing and multi- path detection and one for sound processing. An I2C/SPI interface is implemented for control and communication with the main micro.

A separate SPI is available to interface the display micro.

The DSP cores of the TDA7500 are integrated with their associated data and program memories. The peripherals and interfaces I2C, SPI, Serial Audio Interface (SAI), PLL Oscillator, External Memory 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. The Debug and Test Interface are connected to both DSP cores.

The TDA7500 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.
