Dot Matrix LCD Controller Driver
SED1234/35 Series
I
OVERVIEW
The SED1234, 1235 Series is a dot matrix LCD controller driver for character display, and can display a maximum
of 48 characters, 4 user-defined characters, and a maximum of 48 symbols by means of 4-bit, 8-bit or serial data
sent from a microcomputer.
A built-in character generator ROM is prepared for 256 character types, and each character font consists of 5 x 7
dots. A user-defined character RAM for four characters of 5 x 7 dots are incorporated, and a symbol register is also
incorporated. With these, it is possible to apply this Series to display with a high degree of freedom. This Series
can operate handy units with a minimum power consumption by means of its low power consumption and sleep
mode.
SED1234, and 1235 depending on the duty of use and the number of display columns.
