描述 Description

GPCE2P066B, a 16-bit architecture sound controller, features the 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 processes easily and rapidly. GPCE2P066B 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 GPCE2P066B 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.
