The GPCD9341A(OTP) series work with internal 1M bytes OTP ROM, 512 bytes working SRAM, three sets of 12-bit timer, 32 general I/Os with selectable 8+1 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 GPCD9341A is featured one software channel 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, GPCD9341A features sleep mode for power savings. It can be awakened from sleep mode by interrupt sources or changing IO's state. There is also a Serial Peripheral Interface (SPI) controller built-in GPCD9341A to facilitate communicating with other devices and components.
