Density LCD Controller |
 |
| 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. 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.
