Fujitsu Releases 16-bit Microcontroller for LCD Panel Drivers

Displays up to 192 Segments

Fujitsu Limited

Tokyo, April 02, 2003

Fujitsu Limited, in collaboration with Fujitsu Devices Inc., today announced the release of four new microcontrollers for liquid crystal display panel drivers that can support up a maximum of 192 segments. Designed for use in audio-visual equipment and digital consumer electronics as part of Fujitsu's MB90800 Series, the new products are available starting today.

16-bit Microcontroller for LCD Panel Drivers

With readout panels on audio-visual equipment and consumer electronic products displaying an increasingly large volume of information, the demand for panels that can accommodate large volumes of information on many of these products has increased accordingly. Fujitsu developed this line of controllers to deliver more flexibility for panel design and more processing power.


  1. Capable of controlling LCD displays with up to 192 segments
    The new products are able to drive LCD readouts that have segment readings containing up to 192 elements, an amount 50% greater than the capacity of previous controllers. This enables readouts that can contain, for example, 192 discrete elements, or 27 numerical digits, allowing greater flexibility in panel design.
  2. High-speed operation up to 25 MHz
    The microcontrollers operate at internal clock speeds of up to 25 MHz, enabling high-speed processing.
