DESCRIPTIONThis device is a high-performance, fully programma-
ble DSP, suitable for a wide range of applications and
particularly for Audio and Sound Processing. It con-
tains a 24-bit 50 MIPS DSP core, several interfaces
for control and data, plus a configurable PLL.
The computational power and the memory configura-
tion 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 TDA7535, 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 equali-
sation, Stereo Spatial Enhancement and more.

POWER CONSUMPTIONNote: 50MHz internal DSP clock
PLL CHARACTERISTICSNote: 1. Depending on VCO output frequency.
2. Fdsp = Fvco/2 when PLL is running
OSCILLATOR CHARACTERISTICS
GENERAL INTERFACE ELECTRICAL CHARACTERISTICSNote:1. The leakage currents are generally very small, <1nA. The value given here, 1mA, ia amaximum that can occur after an Electrostatic
Stress on the pin. Human Body Model.
LOW VOLTAGE TTL INTERFACE DC ELECTRICAL CHARACTERISTICS
TDA7502 6/18
Note:1. TTL specifications only apply to the supply voltage range Vdd = 3.0V to 3.6V Takes into account 200mV voltage drop in both supply lines. X is the source/sink current under worst case conditions and is reflected in the name of the I/O cell according to the drive capability.
