Products - GPCE4048B

General Description

GPCE4048B, 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, GPCE4048B is applicable for the areas of digital sound process and voice recognition.  The operating voltage of 2.4V through 5.5V and speed up to 48MHz yield the GPCE4048B to be easily used in varieties of applications.  The memory capacity includes ROM  plus a 4K-word working SRAM and 2K-word Cache RAM (also can be working RAM). Other features including 32 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.
