描述 Description

The GPC3L128A is embedded with an 8-bit processor, 288K~512K bytes ROM and 256-byte working SRAM, three sets of 12-bit timer/counters, 20 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 is designed for wide input voltage (1.0V~1.8V; 1.3V~3.6V), and the circuit works at a programmable pumped voltage (2.7V~4.5V).  Plus, it includes Low Voltage Reset to assure system operating appropriately under low voltage condition.  In addition, GPC3L128A also features the sleep mode for power saving.  With the high cost/performance ratio, GPC3L128A is one of the most suitable engines in the industry for vocal applications.
