描述 Description

GPCE4096UA, a 16-bit architecture sound controller with USB interface, features the newest 16-bit microprocessor, m'nSP2.0? (pronounced as micro-n-SP 2.0). This high processing speed assures the m'nSP2.0? is capable of handling complex digital signal processes easily and rapidly. Therefore, the GPCE4096UA 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 48MHz yield the GPCE4096UA to be easily used in varieties of applications. The memory capacity includes 48K-word ROM plus a 4K-word working SRAM and 2K-word Cache RAM (also can be working RAM). Other features including 48 programmable multi-functional I/Os, five 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), capacitive touch sensor, one SPI flash controller, one 14-bit DAC with push-pull amplifier and many others.
