PF282-07 SED1278F/D Dot Matrix LCD Controller Driver q 1/8, 1/11 or 1/16 Duty Dot Matrix Drive ROM 240 characters q Built-in Character Generator ROM and RAM ( RAM 8 characters ) q Maximum Simultaneous Display of 80 Characters (With extension LCD driver) 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. s FEATURES q Display RAM .............................. 80 bytes (80 characters) q Character generator ROM .......... 240 characters (Able to 256 characters) q Character generator RAM .......... 8 characters q Built-in CR oscillator, Built-in power-on reset circuit q Maximim display dimension ....... 40 characters52 lines, 80 characters51 line (When accompanied with SED1181FLA/DLA, SED1681FOA/DOA) q 1/8, 1/11 or 1/16 duty matirx drive (fixed by command) q 2 flame AC wave-form drive q High-speed bus interface with 4-bit/8-bit MPU q Powerful display control instructions q Character ................................... 5!7 dots+Cursor line (5!8 dots also possible) 5!10 dots+Cursor line q 6 Kinds of character font q Single power supply ................... 5V±10% (Logic) q Low LCD driving voltage ............
