Description

The SED1200F is a dot matrix LCD controller/driver with a built in CG (character generator).

The SED1200F circuit consists of a CG ROM which contains 160 different characters, 4 words CG RAM, 20 words display data RAM and logic functions to operate a 20 character display. Additional characters may be used by writing CG data to the 4 words CG RAM.

The device also contains the resistor array for the LCD power supply. The SED1200F is fabricated Silicon Gate CMOS process and features very low power dissipation. This makes the device very desirable for applications in hand held, portable and other battery powered instruments.
