Products - GPCE4064B_0001

General Description

GPCE4064B_0001, 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, GPCE4064B_0001 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 GPCE4064B_0001 to be easily utilized in varieties of applications.  The memory capacity includes ROM (or OTP) 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.
