General Description

GPCE2048D_0001, a 16-bit architecture sound controller, features a 16-bit microprocessor, m’nSP™ (pronounced as micro-n-SP).  This high processing speed assures the m’nSP™ is capable of handling complex digital signal processing easily and rapidly.  Therefore, GPCE20XXD_0001 is applicable to the areas of digital sound processing and voice recognition.  The operating voltage of 2.4V through 5.5V and speed of 0.140625MHz through 48MHz yield GPCE2048D_0001 to be easily used in varieties of applications.  The memory capacity includes an internal ROM plus a 2K-word working SRAM.  Other features include 21 programmable multi-functional I/Os, three 16-bit timers/counters, 8MHz clock, 32KHz clock, Low Voltage Reset/Detection, four channels 12-bit ADC (one channel built-in MIC amplifier), two type of output by a 12-bit current DAC or by an audio PWM driver, and many others.
