Dot Matrix LCD Controller Driver
PF282-07
q 1/8, 1/11 or 1/16 Duty Dot Matrix Drive
q Built-in Character Generator ROM and RAM (
)
q Maximum Simultaneous Display of 80 Characters
(With extension LCD driver)
SED1278F/D
s DESCRIPTION
The SED1278F/D is a dot matrix LCD controller/driver which is dedicated to character display. It is capable of
displaying up to 80 characters under 4-bit/8-bit MPU control.
The built-in character generator ROM has an extended capacity of 240 different characters, each being generated
in a 5
×10 dots font compatible with a 1/11 duty. In addition, the SED1278F/D contains 64 bytes of character
generator RAM in which the user can store 8 different characters, each consisting of 558 dots. These memory
features offer high flexibility in character display.
The guaranteed minimum LCD driving voltage is 3V, and this makes the SED1278F/D suitable for driving low
voltage LCDs.
