General Description
GPCE4096UA_0001, 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. The GPCE4096UA_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 0.16MHz through 48MHz yield the GPCE4096UA_0001 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 include 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 16-bit DAC with push-pull amplifier and many others.
