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
× 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.
Features
Displayable LCD
Monochrome STN dot matrix type LCD of up to 76800 dots (equivalent to 320 × 240 dots)
Maximum display duty:
1/240 (set to 240 line)
:
1/255 (Max)
Display memory
Built-in 9600-byte (76800-bit) VRAM (equivalent to one screen of 320 × 240 dots LCD)
All addresses of built-in VRAM are externally opened.
Interface with MPU
Capability of switching 8-bit type MPU/16-bit type MPU
With WAIT output pin (Accessing register from MPU without WAIT output. Accessing VRAM from MPU with
WAIT output.)
Capability of controlling BHE or LWR/HWR at the interface with a 16-bit MPU.
Interface with LCD
LCD display data are 4-bit parallel output
4 kinds of control signals: CP, LP, FLM and M
Display functions
Graphic display only (characters drawn graphically)
Binary display only (without tone display function)
Vertical scrolling is allowed within memory range (small size LCD only)
Additional function for LCD module built-in system
15 kinds of interface with MPU: A <4:1>, D <7:0>, IOCS, LWR, RD
Accessing VRAM from MPU through I/O register
Capability of interfacing with 8-bit type MPU only
5 V single power supply
80-pin QFP
Application
PPC/FAX operation panel, display/operation panel of other OA equipment
Multi-function/public telephones
PDA/electronic notebook/information terminal
Other applications using LCD of 76800 dots or less
