GPC3002A

3-Channel Sound Controller; • Wide Operating Voltage: 2.0V * - 5.5V * The lowest operating voltage depends on LVR (Low Voltage Reset) level. Typical LVR voltage is 2.0V but with+/- 0.1V deviation possibility\n• Working Voltage with 6MHz system clock: 2.2V ** - 5.5V\n• Working Voltage with 8MHz system clock: 2.4V ** - 5.5V** The system clock would start to slow down at lowest working voltage (6MHz at 2.2V, 8MHz at 2.4V); please refer to the Frequency vs. VDD curve on page 12\n• External 4M bytes maximal memory (SRAM/Flash)\n• 256-byte working SRAM\n• Generalplus ICE_CORE embedded\n• Built-in internal (8MHz or 6MHz) or external RC oscillator\n• Standby mode (Clock Stop mode) for power savings.\n• Max. 5.0uA @ 4.5V\n\n• 32 general I/Os (including four high brightness LED driving I/Os)\n• Three 12-bit timer/counters\n• 8 IRQs & 1 NMI interrupts\n• Three wake-up sources\n• Feedback function\n• Low Voltage Reset (LVR) function\n• Watchdog function\n• IR function\n• RTC function\n• Four sets of 256 level PWMIO outputs\n• A 3-channel mixer with melody or ADPCM/PCM input\n• A pair of PWM outputs with volume control;

The GPC3002A is embedded with an 8-bit processor, a set of A/D bus for external program/data memory (maximal 4M bytes SRAM/Flash) and 256-byte working SRAM, three sets of 12-bit timer/counters, 32 general I/Os, a 3-channel mixer, a pair of 12-bit PWM outputs and a Real Time Clock(RTC). 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. It operates over a wide voltage range from 2.0V through 5.5V, and it includes Low Voltage Reset to assure system operating appropriately under low voltage condition. In addition, GPC3002A also features the sleep mode for power saving. With the high cost/performance ratio, GPC3002A is one of the most suitable engines in the industry for vocal applications.
