NJU6468 General Description

The NJU6468 has the following features including 5 x 7 and 5 x 10 Fonts pith Cursor Displav;4/8 Bits Microprocessor Direct Interface;Disalay Data RAM(80 x 8 bits):Maximum 80 Characters;Character Generator ROM(12,000 bits):240 Characters for 5 x 1Q Dots;Character Generator RAM(64x 8 bits):8 Patterns(5x7 Dots) and 4 Patterns(5x10 Dots);Microprocessor can access to Display Data RAM and Character Generator RAM.

The NJU6468 is a Dot Matrix LCD controller driver for 8-character 2-line display with extension function up to 40-character 2-line display.It contains microprocessor interface circuits. instruction decoder controller. character generator fuel/RAM, high voltage operation comioon and segment drivers.and extension driver interface circuits.The microprocessor interface circuits which overate by 2NMz frequency, can be connected directly to 4/8bit microprocessor.The character generator consists of 12k bits ROM and 64 bytes RAM. The standard version ROM is coded with 240 characters including capital and shall fetter fonts and some of Japanese fonts. The hihg voltage operation 16-common and 40-segment drivers operate up to 13.5V,and drive up to 8-character 2-line display in single NJU6468 use.The extension driver interface circuits enable combinations with NJ116407C or NJU6417C to increase the display capacity up to 40-character 2-line or 80-character 1-line.

When the address data for the DD RAM or CG RAM is written into the Register(IR),the ad-dressed data in the DD RAM or CG RAM is transferred to the Register(DR).By the MPU read out the data in the Register(DR),the data transmitting process is performed completely.The extension driver for example NJU6407C/07CR's segment driver structure is as same as NJU 6468 segment driver. The 40 bits of character pattern data are shifted in the shift-register and latched when the 40 bits shift performed completely. This latched data controls display driver to output LCD driving waveform.Since the serial data always transfer from the last character pattern (last address dispiay data in the DD RAM) and latched when the top of character pattern (top address display data in the DD RAM) read out from the DD RAM, the NJU6468 always display from the top character and every extended extension driver display following character than front.
