PT6586 Datasheet | PTC

PT6586 LCD Control/Driver IC DESCRIPTION The PT6586 is 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The PT6586 can drive an LCD with up to 140 segments directly. The PT6586 can also control up to 4 general-purpose output ports. Features - Up to 140 segments for 1/4 duty drive can be displayed - Serial interface for clock, Data Input, Strobe pins - Serial data control of the power-saving mode based backup function and all the segments forced off function - Serial data control of switching between the segment output port and the general-purpose output port functions - Serial data control of frame frequency for mon and segment output waveforms - High generality, since display data is displayed directly without decoder intervention - The INHB pin can force the display to the off state - RC oscillator circuit APPLICATION - Electronic equipment with LCD Display BLOCK DIAGRAM Tel: 886-66296288‧Fax: 886-29174598‧ http://.princeton..tw‧2F, 233-1, Baociao Road, Sindian, Taipei 23145, Taiwan For:Natertech Free Datasheet http://.0PDF. APPLICATION CIRCUIT Note:- = When a capacitor except the remended external capacitance (Cosc = 1000 p F) is connected the OSC pin, we remend that applications connect the OSC pin with a capacitor in the range 220 to 2200 p F.
