Products - GPCE2P064A (OTP)

General Description

GPCE2064A, a 16-bit architecture sound controller, features 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 GPCE2064A 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 GPCE2064A to be easily used in varieties of applications. The memory capacity includes 32K-word ROM plus a 2K-word working SRAM. Other features include 32 programmable multi-functional I/Os, three 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection, eight 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.
