LCD CONTROLLER with VRAM
M66273FP
MITSUBISHI <DIGITAL ASSP>
Ver.3.1 Dec,1999
DESCRIPTION
The M66273 is a graphic display-only controller for dot matrix type STN-
LCD which is used widely for OA equipment, PDA, amusement
equipment, etc.
The M66273 is an advanced product from the M66272 at the point of MPU
interface and timing specifications. This LCD display functions are the
same with the M66272.
It is capable of displaying six types of LCD by combining the panel
configuration(single or dual scan), LCD display function(binary or gray
scale), LCD display data bus width(4 or 8 bit).

The M66273 can support the reflective color type LCD (ECB : Electrically
Controlled Birefringence).
The IC has a built-in 19200-byte VRAM as a display data memory. All of
the VRAM addresses are externally opened. Direct addressing of display
data can be performed from MPU, thus display data processing such as
drawing can be efficiently carried out.
The built-in arbiter circuit(cycle steal system) which gives priority to
display access allows timing-free access from MPU to VRAM, preventing
display screen distortion.
The IC provides has a function for LCD module built-in system by
lessening connect pins between the MPU and the IC.
