MC141539T1R

The MC141539T1R is one member of the MC141539 family which is designed as the LCD segment / common driver with controller CMOS that consists of 4 annunciator outputs and 152 high voltage LCD driving signals (32 commons and 120 segments). It has parallel interface capability for operating with general MCU. Besides the general LCD driver features, it has on chip LED bias voltage generator circuit such that fewer external components are required during application.

Features of the MC141539T1R are:(1)single supply operation, 2.4V to 3.5V;(2)operating temperature range: -30 to +85;(3)low current stand-by mode (<500 nA);(4)on chip bias voltage generator;(5)8 bit parallel interface;(6)graphic mode operation;(7)on chip 480 byte graphic display data RAM;(8)120 segment drivers, 32 common drivers;(9)selectable 1/16 or 1/32 multiplex ratio;(10)selectable on chip voltage doubler and tripler;(11)selectable 1:5 or 1:7 bias ratio;(12)re-mapping of row and column drivers;(13)16 level internal contrast control.

The absolute maximum ratings of the MC141539T1R can be summarized as:(1)supply voltage AVDD, DVDD:-0.3 to +4.0 V;(2)supply voltage Vcc: Vss-0.3 to Vss+10.5 V;(3)input voltage: Vss-0.3 to Vss+0.3 V;(4)current drain per pin excluding VDD and Vss: 25 mA;(5)operating temperature for using internal oscillator: -25 to +85;(6)operating temperature for using external oscillator: -30 to +85;(7)storage temperature range: -65 to +150.
