Overview
® TDA7502 IN-CAR REMOTE AMPLIFIER DSP PRODUCT PREVIEW 24-Bit Fixed-point DSP core delivering up to 50 MIPS 2 x 512 x 24Bitof RAM forX andY datamemory.
1536 x 24 Bit of RAM for Program.
1536 x 24 Bit of Additional RAM memory usable for delay or program Serial Audio Interface.
Debug Port.
Control Interface for external GPIOs, Interrupts, and RESET.
SPI and I2C for communication between external micro and DSP.
Both master and slave operating modes.
PLL Clock Oscillator 5V-tolerant 3V I/O interface DESCRIPTION This device is a high-performance, fully programmable DSP, suitable for a wide range of applications and particularly for Audio and Sound Processing.
It contains a 24-bit 50 MIPS DSP core, several interfaces for control and data, plus a BLOCK DIAGRAM SDI0 SDI1 SDI2 SDO0 SDO1 SDO2 TQFP44 (10 x 10) configurable PLL.
The computational power and the memory configuration make this device particularly suitable for in car equalisation.
This device will offer the best trade-off between performance and cost when coupled with the TDA7531, or other devices of the same family.
A library of sound processing functions is available for this device; some of these functions are: parametric equaliser, cross over filters, acoustic delay, dynamic compression, Vol/Bass/Treble/Fader, active equalisation, Stereo Spatial Enhancement.
