Version: 1.4

16-BIT SOUND CONTROLLER WITH

24K X 16 ROM

1. GENERAL DESCRIPTION

The GPCE040A, a 16-bit architecture product, carries the newest

16-bit microprocessor,

μ’nSP™ (pronounced as micro-n-SP),

developed by Sunplus Technology.

This high processing speed

assures the

μ’nSP™ is capable of handling complex digital signal

processes easily and rapidly.

Therefore, the GPCE040A is

applicable to the areas of digital sound process and voice

recognition.

The operating voltage of 2.4V through 3.6V and

speed of 0.32MHz through 49.152MHz yield the GPCE040A to be

easily used in varieties of applications.

The memory capacity

includes 24K-word fast-speed ROM plus a 2K-word working

SRAM. Other features include 32 programmable multi-functional

I/Os, two 16-bit timers/counters, 32768Hz Real Time Clock, Low

Voltage Reset/Detection, eight channels 10-bit ADC (one channel

built-in MIC amplifier with auto gain controller), 10-bit DAC output

and many others.
