UPD6450CX-002

The UPD6450CX-002 is one member of the UPD6450 family which is designed as the on-screen character display CMOS LSI which is combined with microcomputers and used for VTR and video disks to display program reserved information, chapter numbers, etc. on monitor screens. Character format is 12 x 18 dots, and one character enables displaying numbers kanji and hiragana. Since this LSI has built-in video switches, video signals can be input and output by composite video signals, and video signals can be generated internally so that characters can be displayed with no external signals.

Features of the UPD6450CX-002 are:(1)number of displayed character: 12 lines, 24 columns;(2)kinds of character: 128 (ROM);(3)character size: 1 dot - 1H, 2H, 3H or 4H;(4)dot matrix: 12 x 18 dots - with no clearance between neighboring characters;(5)blinking ratio: 1:1, 3:1 or 1:3;(6)input / output of image signal: composite video signal;(7)power supply: +5 V single power supply;(8)structure: low power consumption CMOS.

The absolute maximum ratings of the UPD6450CX-002 can be summarized as:(1)supply voltage: 7 V;(2)input voltage: VDD+0.3 > VIN > Vss-0.3 V;(3)output voltage: VDD+0.3 > Vout > Vss-0.3 V;(4)operation temperature: -20 to +75 ;(5)storage temperature: -40 to +125 ;(6)output current: +/- 5 mA.
