16-BIT SOUND CONTROLLER

WITH 32K X 16 ROM

1 GENERAL DESCRIPTION

GPCE2064C, a 16-bit architecture sound controller, features a

16-bit microprocessor

’nSP™ (pronounced as micro-n-SP) to

handle complex digital signal processes

efficiently.

The

operating voltage from 2.4V to 5.5V and clock speed from

0.140625MHz through 48MHz allows GPCE2064C to be adopted

in variety of applications.

Furthermore, it also features a

32K-word ROM with a 2K-word working SRAM memory, 20

programmable multi-functional I/Os, three 16-bit timers/counters,

32KHz clock, Low Voltage Reset/Detection, one 14-bit DAC with

push-pull amplifier, and many others.
