The GPC3010A is embedded with an 8-bit processor, 32K bytes ROM, 128-byte working SRAM, three sets of 12-bit timer/counters, 16 general I/Os, a 3-channel mixer, and a pair of 12-bit PWM outputs. 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, GPC3010A also features the sleep mode for power saving. With the high cost/performance, GPC3010A is one of the most suitable engines in the industry for vocal applications.
*1: The lowest operating voltage depends on LVR(low voltage reset) level. Typical LVR voltage is 2.0V but with +/- 0.1V deviation possibility
*2: 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_REGIN curve
