GENERAL DESCRIPTIONS

SN6B000 is a 8-bit micro controller series with hi-density LCD driver. Combined with one or more SN6BS00 (64-segment drivers), SN6B000 can form one 1024/ 2048/ 4096/ 6144/ 8192 dots LCD system. A dual-tone melody and a voice synthesizer are included in SN6B000. Also, a 7-bit current-type DAC and the PWM circuit are built in SN6B000, so that makes users easily choose a speaker (DA), or a buzzer (PWM) for their applications.
