The GPCH4A24A embedded with an 8-bit processor, 1M bytes ROM chip, 512 bytes working SRAM, three 12-bit timers, 32 general I/Os, and two 12-bit DACs. The microprocessor can implement software based on audio processing, functional control and others. For audio processing, melody and speech can be mixed into one output. The GPCH4A24A features a high performance SPU voice engine to achieve 8 channel voice with ADPCM/PCM. It operates over a wide voltage range of 2.4V - 5.5V and includes Low Voltage Reset function. In addition, GPCH4A24A provides sleep mode for power savings. It can be awakened from sleep mode by external interrupt source or IOA's state change.\n\n\n\n
