The GPCE512A is equipped with the newest 16-bit CPU μ'nSP? (read as 「micro-n-SP」) designed by SUNPLUS. It's high processing speed empowered the μ'nSP? ISA 1.3 capable of handling sophisticated digital signal processes (DSP) computation easily. The wide range of CPU speed, from 0.1875MHz to 48MHz, makes the GPCE512A to be easily applied in different kinds of applications. The built-in memory contains 256K-word mask ROM and 2K-word working SRAM. Other features including 32 programmable multi-functional I/Os, three 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection, eight channels of 12-bit ADC (one channel built-in MIC amplifier with Auto Gain Controller). One very important feature is GPCE512A built-in very high quality, one 16-bit DACs, this provides GPCE512A being able to output very high quality sound and music. Another two IO PWM outputs provide the convenience of generating some duty-cycle wave form signals. A power saving mode, halt mode, is designed to only stop CPU clock but reserve others. To save even more power, a sleep mode is available to stop all clocks. These two modes can be awakened from the I/O or interrupt source triggers.
