SED1225 Series
LCD Controller Driver
I
DESCRIPTION
The dot-matrix LCD controller driver SED1225 is designed to display characters and capable of displaying up to
36 characters, 4 user-defined characters and 120 symbols using 4- or 8-bit or serial data sent from the
microcomputer.
The built-in character generator ROM is equipped with up to 256 types of character fonts, which consist of 5
×
8
dots respectively. The user-defined character RAM for 4 characters of 5
×
8 dots is also built in, enabling display
of high degree of freedom through the symbol register. Thanks to its ultra-low power consumption, sleep and
standby modes, it can operate handy equipment with the minimum power demand.
