SN6B000
Hi-Density LCD Driver with 8-bit Controller
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. SN6B000 only contains 32 COM
signals of LCD. All segment signals are provided by SN6BS00. Several
different types of LCD applications can be implemented by suitably combining
SN6B000 and SN6BS00. SN6B000 not only contains internal mask ROM itself
(128K words, MC mode), but also possesses the interface to access external
ROM (maximum 512K words, MP mode). A memory chip, SN6B400 consists of
256K-word mask ROM and is available to work with SN6B000 to accomplish the
whole micro-processor system.
