LCD CONTROLLER with VRAM
M66272FP
MITSUBISHI <DIGITAL ASSP>
PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
DESCRIPTION
The M66272FP is a graphic display-only controller for dot matrix
type STN-LCD which is used widely for OA equipment, PDA,
amusement equipment, etc.
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 M66272FP 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.
FEATURES
Display memory
Built-in 19200-byte(153.6-Kbit) VRAM(Equivalent to 320 x 240
dots x 2 screens)
All addresses of built-in VRAM are externally opened.
