LOW POWER 3-CHANNEL SOUND CONTROLLER

1. GENERAL DESCRIPTION

3. FEATURES

The GPC3LP170A is embedded with an 8-bit processor, 512k

bytes OTP 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, GPC3LP170A also

features the sleep mode for power saving.

With the high

cost/performance ratio, GPC3LP170A is one of the most suitable

engines in the industry for vocal applications.

8-bit microprocessor

512K bytes OTP ROM.

256-byte working SRAM

Wide input voltage: 1.0V~1.8V (one battery)

1.3V~3.6V (two battery)

*Lower input voltage could drive lighter loading only.

Pumped voltage (DC-DC) for VDDIO and VDD_REGIN

power:2.7V~4.5V;Step:0.3V

*The output pumped voltage would be larger or equal to input

voltage

Operating clock : 8.0MHz

Three system clock sources: IOSC(8MHz), ROSC and XTAL

Standby mode (Clock Stop mode) for power savings.
