Digitally Programmable 8 to 25 Multiplex
LCD Controller & Driver
Description
The EM6124 is a low power CMOS LCD controller and
driver. The 8, 16, 20 and 24 way multiplex are digitally
programmable 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 corresponds 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 portable 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.
Applications
Mobile phones (GSM, DECT)
Smart cards
Automotive displays
Portable, battery operated products
Balances and scales, utility meters
Features
