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 VDD
= 2 V, VLCD = 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.
