SED1240 Series
SED1240
Series
OVERVIEW
The SED1240 Series is a character display dot matrix
LCD controller driver. This driver can display up to 64
characters and 6 user-defined characters, and up to 160
symbols according to the 4-bit, 8-bit or serial data which
is sent from a microcomputer.
The built-in character generator ROM is provided with
up to 544 types of character fonts having a structure of 5
× 8 dots. Up to 256 types can be continuously called by
register option selection. This can cope with many
different character fonts by uses and countries and permits
a wider range of use. This driver incorporates a user-
defined character RAM for 6 characters of 5
× 8 dots and
can be used for the display of higher degree of freedom
by means of a symbol register.
The driver can operate handy units at the minimum
power consumption by using its merit of lower power
consumption, standby mode, and sleep mode.
