LOW POWER 3-CHANNEL SOUND CONTROLLER

1. GENERAL DESCRIPTION

GPC3LXXXX is embedded with an 8-bit processor, 288K~512K

bytes

ROM

and

256-byte

working

SRAM,

three

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).

GPC3LXXXX 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).

In

audio processing, both melody and speech is capable of being

mixed together into one output.

Furthermore, it contains a Low

Voltage Reset to assure system operating appropriately under low

voltage condition and a sleep mode to save power while system is

standing by.

With a high cost/performance ratio characteristic,

GPC3LXXXX is one of the most suitable engines in the industry

for vocal applications.
