M66272FP

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 M66272FP IC provides has a function for LCD module built-in system by lessening connect pins between the MPU and the IC.
