General Description

The GPCD6L106A features a 320KB internal ROM, 512-byte working SRAM, three 12-bit timers, 20 general I/Os with multi-channel input and one 14-bit DAC with amplifier. In audio processing, melody and speech can be mixed into one output and it is featured a maximum of two sets of software channels and a high performance SPU voice engine to perform high quality voice function with ADPCM/PCM data. To save more power in the device, GPCD6L106A features a sleep mode to make CPU enter sleep state while not is use. Although in power saving mode, it is able to wake up rapidly if any interrupt source or wakeup IO is triggered. A Serial Peripheral Interface (SPI) controller helps GPCD6L106A to communicate with other devices and components easily and efficiently.
