Description

The EM6124 is a low power CMOS LCD controller and

driver. The 8, 16, 20 and 24 way multiplex are digitally pro-

grammable by the command byte. One additional line can

be added for Icons or Inverted Video by programming 9,

17, 21 or 25 way multiplex. The display refresh is handled

on chip by an internal RC oscillator via one selectable 25 x

116 RAM which holds the LCD content driven by the

driver. LCD pixels (or segments) are addressed on a one

to one basis with the 25 x 116 bit RAM (a set bit corre-

sponds to an activated LCD pixel). The EM6124 has very

low dynamic current consumption, typically 70 µA at V_DD

= 2 V, V_LCD= 7 V making it particularly attractive for porta-

ble and battery powered products. The wide operating

range on supply voltages and temperature offers much

application flexibility. The LCD voltage, bias generation

and frame frequency are generated on chip. The clock

signal can be used to shift and to latch the data into the

RAM.
