Dot Matrix LCD Controller Driver PF282-07 l 1/8, 1/11 or 1/16 Duty Dot Matrix Drive l Built-in Character Generator ROM and RAM ( ) l Maximum Simultaneous Display of 80 Characters (With extension LCD driver) SED1278F/D n 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. n FEATURES l Built-in CR oscillator, Built-in power-on reset circuit (When accompanied with SED1181FLA/DLA, SED1681FOA /DOA ) l 1/8, 1/11 or 1/16 duty matirx drive (fixed by command) l 2 flame AC wave-form drive l High-speed bus interface with 4-bit/8-bit MPU l Powerful display control instructions 55 10 dots+Cursor line l 6 Kinds of character font SED1278D: Die form (Al pad) n BLOCK DIAGRAM ROM 240 characters RAM 8 characters Instruction Decoder MPX MPX MPX Display Data RAM DD RAM
