Dot Matrix LCD Controller Driver PF135-08 l 1/8 or 1/16 Duty Dot Matrix Drive l 20 Character Simultaneous Display l Built in Character Generator ROM and RAM SED1200F n DESCRIPTION The SED1200F is a dot matrix LCD controller/driver with a built in CG (character generator). The 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. n FEATURES l 1/8 or 1/16 duty cycle dot matrix drive l 20 character simultaneous display l Built in character generator ROM and RAM l Built in CR oscillator l Built in resistor array for LCD power supply l Compatible with 4 or 8 bit microprocessors l 2 kinds of character font l TTL Compatible l 5×7+Cursor line or 558 character font l Power supply Logic : 2.5V to 5.5V LCD : 3.5V to 5.5V SED1200D : Die form n BLOCK DIAGRAM CLK Input Controller Address Counter Address Controller Address Counter Common Generator Common Driver LC Power SupplyCGROM 160 words Segment Signal Generator Segment Driver SEG1 SEG50 V SS VDD VLCD COM16 COM1 OSC1 OSC2 LC Power Divider Instruction Register DDRAM 105 2words (160 bits) Write/Read Controller Latch CGRAM CGRAM 5 5 8 dots5 4 (160 bits) Write/Read Controller Data Controller Timing Generator Oscillator Timing Generator WR RD CS DB0 DB1 DB2 DB3 Wide VoltageOperation Products
