16-BIT SOUND CONTROLLER

WITH 24K X 16 ROM

1 GENERAL DESCRIPTION

GPCE2048A, a 16-bit architecture sound controller, features the

16-bit

’nSP™ microprocessor

developed

Sunplus

Technology.

This high processing speed assures the

’nSP™ is

capable of handling complex digital signal processing easily and

rapidly.

GPCE2048A is applicable to the areas of digital sound

processing and voice recognition.

The operating voltage of 2.4V

through 5.5V and speed of 0.16MHz through 49.152MHz yield

GPCE2048A to be utilized in varieties of applications.

The

memory capacity includes 24K-word ROM and a 2K-word

working SRAM.

Other features include 20 programmable

multi-functional I/Os, three 16-bit timers/counters, 32768Hz Real

Time Clock, Low Voltage Reset/Detection, four channels 12-bit

ADC (one channel built-in MIC amplifier with auto gain controller),

one 14-bit DAC with push-pull amplifier and many others.
