The GPCDXXXXA series work with internal 128K~1M bytes ROM, 512 bytes working SRAM, three sets of 12-bit timer, 16~32 general I/Os with selectable 8+1/4+2/1+2 channels input and one 14-bit DAC with push-pull amplifier. The microprocessor implements software based on audio processing, functional control and others. For audio processing, melody and speech can be mixed into one output. The GPCDXXXXA is featured maximum two software channels and a high performance SPU voice engine to play voice with ADPCM/PCM data. It operates over a wide voltage range and includes Low Voltage Reset function. In addition, GPCDXXXXA provides sleep mode for power savings. It can be waked up from sleep mode by interrupt sources or changing IO's state. There is a Serial Peripheral Interface (SPI) controller built-in some GPCDXXXXA bodies to facilitate communicating with other devices and components.
