1 / 34 page  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.
