EM6124 - Digitally Programmable 8 to 25 Multiplex LCD Controller & Driver

General 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.

Key Features

  • Slim IC for chip-on-board, with gold bumps for Chip-On- Glass and Chip-On-Flex technologies.
  • Very simple 2-wire interface.
  • Digitally programmable multiplex rates: 8 x 113, 9 x 112, 16 x 105, 17 x 104, 20 x 101, 21 x 100, 24 x 97, 25 x 96.
  • No lost pads while row driver from 8 up to 25.
  • On chip: Voltage multiplier, VLCD up to 7 V (3 to 6 V at 25 °C), 64 VLCD digitally programming steps, 4 VLCD temperature compensation factors, bias generation, VON / VOFF generation, frame.

EM MICROELECTRONIC - MARIN SA EM6124 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).
