GPCE2P064D, 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, GPCE2P064D 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 GPCE2P064D to be easily used in varieties of applications. The memory capacity includes a 32K-word OTP 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 types of output by a 12-bit current DAC or an audio PWM driver, and many others.
