Products - GPCE4V000UA

General Description

GPCE4V000UA, a 16-bit architecture sound controller with USB interface, features a 16-bit microprocessor, m’nSP2.0™ (pronounced as micro-n-SP 2.0). The GPCE4V000UA is applicable to digital sound processing and voice recognition. The operating voltage of 2.4V through 5.5V and speed of 0.047MHz through 48MHz yield the GPCE4V000UA to be easily used in varieties of applications. The memory capacity includes a max 10K-word working SRAM. 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, two 16-bit DAC with push-pull amplifier and many others.
