20102rm (ot) no.7159-1/26 http://onsemi.com semiconductor components industries, llc, 2013 october, 2013 LC75813E, lc75813t overview the LC75813E and lc75813t are 1/3 duty and 1/4 duty general-purpose lcd drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. the LC75813E and lc75813t can drive an lcd with up to 344 segments directly. the LC75813E and lc75813t can also control up to 8 general- purpose output ports. since the LC75813E and lc75813t use separate power supply systems for the lcd drive block and the logic block, the lcd driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage. features ? switching between 1/3 duty and 1/4 duty drive techniques under serial data control. ? switching between 1/2 bias and 1/3 bias drive techniques under serial data control. ? up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed. ? serial data input supports ccb format communication with the system controller. ? 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 common and segment output waveforms. ? high generality, since display data is displayed directly without decoder intervention. ? independent v lcd for the lcd driver block (v lcd can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.) ? the inh pin can force the display to the off state. ? rc oscillator circuit package dimensions unit : mm [ LC75813E ] [ lc75813t ] cmos lsi 1/3, 1/4 duty general-purpose lcd drive r ordering number : en7159 ? ccb is a registered trademark of semiconductor components industries, llc. ? ccb is on semiconductor? ?s original format. all addresses are managed by on semiconductor? for this format. qip100e(14x20) 20.0 23.2 14.0 17.2 0.15 0.8 (2.7) 3.0max 0.1 0.3 0.65 (0.58) 130 80 51 31 50 100 81 tqfp100(14x14) 100 125 26 50 51 75 76 14.0 (1.0) (1.0) 0.1 0.125 16.0 0.2 0.5 1.2max 0.5 14.0 16.0
