The M66271FP is a graphic display-only controller for displaying a high duty dot matrix type LCD which is used widely for PPC,FAX and multi-function telephones.
It is capable of controlling a monochrome STN LCD system of up to 320 x 240 dots.
The IC has a built-in 9600-byte VRAM as a display data memory.
All of the VRAM addresses are externally opened. Address mapping in the MPU memory space allows direct addressing of all display data from the MPU,thus providing efficient display data processing such as drawing.
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 interface with a 8-bit/16-bit MPU with a READY(WAIT) pin.
And this IC has a function for LCD module built-in system by lessening connect pins between MPU.
