16-BIT SOUND CONTROLLER

1 GENERAL DESCRIPTION

GPCE2P064B, a 16-bit architecture sound controller, features the

newest

16-bit

microprocessor,

’nSP™ (pronounced as

micro-n-SP).

This high processing speed assures the

’nSP™

is capable of handling complex digital signal processes easily

and rapidly.

Therefore, the GPCE2P064B is applicable to the

areas of digital sound process and voice recognition.

The

operating voltage of 2.4V through 5.5V and speed of 0.16MHz

through 49.152MHz yield the GPCE2P064B to be easily used in

varieties of applications.

The memory capacity includes a

32K-word OTP ROM plus a 2K-word working SRAM.

Other

features include 20 programmable multi-functional I/Os, three

16-bit

timers/counters,

32KHz

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.
