General Description

GPCE1S16A, a 16-bit architecture sound controller, 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, GPCE1SXXA is applicable for the areas of digital sound process. The operating voltage of 2.2V through 5.5V and speed up to 81.92MHz yield the GPCE1S16A to be easily used in varieties of applications. The memory capacity includes a 3K-word working SRAM and 2K-word Cache RAM (also can be working RAM). Other features including 34 programmable multi-functional I/Os, five 16-bit timers/counters, 32KHz Real Time Clock, Low Voltage Reset/Detection, ten channels 12-bit ADC, capacitive touch sensor, one 12-bit current DAC and 16-bit PWM out for audio.
