2 Line of 20 Characters 9mm High High Speed Parallel/TTL Serial Interface Operating Temp -40C to +85C Single 5V Supply High Brightness Blue Green Display ASCII, Katakana & Extended Character Font 16 User Definable Character RAM
CU20029-KTW220A
The module includes the Vacuum Fluorescent Display glass, driver and micro-controller ICs with refresh RAM, character generator and interface logic. The high speed 8 bit parallel interface is 5V CMOS compatible suitable for connection to a host CPU bus. The asynchronous serial interface accepts baud rates up to 19,200 with or without parity. Two character font tables can be hardware or software selected. User defined characters and many control commands are available.

Description
Moves the cursor left by one character. If the cursor is at the left end of the display no cursor movement is made. Moves the cursor right by one character. If the cursor is at the right end of the display the action depends on the write mode currently selected. In DC1 and DC2 mode no cursor movement is made. In DC3 mode the entire contents of the display is scrolled left by one character, the right end character position is cleared. No cursor movement is made. The display is cleared. No cursor movement is made. Moves the cursor to the left end. Moves the cursor to the left end. Clear all displayed characters. No cursor movement is made. Clear all displayed characters. No cursor movement is made. Specifies automatic carriage return mode. (default) Specifies character overwrite mode. Specifies horizontal scroll mode. The cursor is turned off The cursor is displayed as a blinking full block. The blink rate can be specified using the Blink Speed Control command. The cursor is turned off The cursor is turned off All subsequent characters displayed will be from the International font. This font can also be selected as the default by using the J6 hardware jumper link (OPEN). All subsequent character displayed will be from the KATAKANA font. This font can also be selected as the default by using the J6 hardware jumper link (LINKED). This command enables the Euro currency mark at location ADH in the International font. Sending the International Font command (or after a reset) restores the character at location ADH to a blank (this is the default condition). This will affect any existing ADH characters already on the display. Define a user character. Up to 16 user characters can be defined and stored by the module. The specified character code can be 00H - FFH. Command codes Dot assignment can be overwritten with a UDF so be aware that doing so will disable that command. All UDF's are lost on power off or reset. If more that 16 UDF's are P1 P2 P3 P4 P5 defined the older definitions are overwritten.

The cursor is moved to the specified position. The relationship between the position value and the display is as follows:Left end 2nd col 3rd col Right end Top Bottom 00H 14H 01H 15H 02H 16H 13H 27H

Blink Speed Control

The display luminance can be set to one of 4 levels. luminance = 00H - 3FH specifies 25% luminance = 40H - 7FH specifies 50% luminance = 80H - BFH specifies 75% luminance = C0H - FFH specifies 100% (default) Set flickerless write mode. By default, priority is given to data communication and display flicker can occur if data is sent to the display continuously. If flickerless writing mode is specified, priority is given to display refresh to avoid possible flicker. Command and data busy times will be up to 200us longer when this mode is set. The blink rate of the cursor can be specified. Rate = speed x 30ms. (default=14H)
Initialise
6us (1BH) 40us (49H)
Clear the display, erase any defined characters, set the cursor position to the top left of the display and reset all settings to defaults. Display the specified character from the currently selected font (or UDF is defined) at the current cursor position. After the character is written to the display a horizontal tab automatically follows.

PARALLEL COMMUNICATION
CU20029-KTW220A
Data on D0-D7 is clocked into the module when /CS is low and a rising edge is detected on /WR. The host must keep the data stable for the time period indicated in the timing diagram. The module busy line can be used to give a sufficient delay between commands.
