M66271FP General Description

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.

M66272FP General 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.

M66272FP Features

1. 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.
2. Displayable LCD
    • Binary display
   Monochrome STN-LCD of up to 153600 dots(equivalent to 1/2VGA)
• 4 gray scale display
   Monochrome STN-LCD of up to 76800 dots(equivalent to 1/4VGA)
   Reflective color STN-LCD of up to 76800 dots (equivalent to1/4 VGA)
3. Interface with MPU
   • Capability of switching the interface with two-way 8/16-bit MPU
   • Provides WAIT output pin(WAIT output when access from MPU to VRAM is gained)
   • Capability of controlling BHE or LWR/HWR at the interface with a 16-bit MPU
4. Interface with LCD
   • LCD display data bus is a 4-bit or 8-bit parallel output.
   • 4 kinds of control signals: CP, LP, FLM and M
5. Display functions
   • Graphic display only
   • Binary or 4 gray scale display(gray scale palette is used to set pseudo medium 2 gray scale.)
   • Reflective color(ECB) uses a gray scale function.
   • Vertical scrolling is allowed within memory range.
6. Additional function for LCD module built-in system
   • Capability of interfacing with two-way 8/16-bit MPU(16-bit MPU byte access is not allowed.)
   • Access from MPU to VRAM is gained via the I/O register.
7. 5V or 3V single power supply

M66272FP Typical Application

• PPC/FAX operation panel, display/operation panel of other OA equipment, multifunction/public telephone
• PDA/electronic notebook/information terminal, portable terminal
