www.vishay.com 3 apd-480m021/-2 vishay dale document number: 37054 revision 27-nov-00 general description the apd-480m021 consists of a dc plasma panel display, drive circuitry, and controller. the interface is a basic 8 bit parallel ascii interface with handshaking and some dedi- cated control lines. vishay dale's ? patented open construction display technol- ogy assures a stable, flicker free screen. the controller maintains all the refresh memory, character generation and control logic. it supports back space, horizontal tab, line feed, vertical tab, clear, carriage return and escape through software instructions. control com- mands available include reading cursor position and data, horizontal tab after reading data at cursor position, character insert, character delete, line insert, line delete and screen clear. operating modes are "normal" (wrap-around) or vertical scroll. the cursor may be turned on, or off, or on with a 4 hz blink rate. the eprom based character generator is programmed with an ascii character set, but is easily configured for any character set. the logic input is one 74ls type input with 4.75 kilohm to + 5 vdc. all input lines also have a 1000 f capacitor to ground. interface signal description db0-db7 (data bus) - tri-state bi-directional data bus to exchange data between display and host processor. chk (check command) - if chk is low, any character written will fill all positions on the screen. after chk is low, momentarily pulling clr low will start a self-test where all the characters in the character set are scrolled from right to left. wr (write) - enter data while wr is low. rd (read) - read data while rd is low. a0 (address bus) - selects character control codes or control command. a0 = low enables writing data. us (unit select) - read and write commands will only influence display while us is low b/d (brightness/dim) - brightness is reduced 50% when b/ d is low. bl (blank screen) - screen blanked when bl is low, but the data and cursor are maintained. clr (clear display) - display memory is cleared and the cursor goes to the home position when clr is low. busy (busy signal) - i/o is inhibited while busy is high. this output is driven from a 74ls06 open collector output and is not pulled up. function summary control codes hex back space 08 horizontal tab 09 line feed 0a vertical tab 0b clear 0c carriage return 0d read cursor position f0 read data at cursor position f1 read cursor position data, then perform horizontal tab f2 character insert f3 character delete f4 line insert f5 line delete f6 screen clear ff escape control codes alter cursor position 1b row position ## column position ## pin description pin description j1 data connector 1 data bit 0 3 data bit 1 5 data bit 2 7 data bit 3 9 data bit 4 11 data bit 5 13 data bit 6 15 data bit 7 17 wr 19 us 21 rd 23 clr 2, 26 gnd 4 b/d 6a0 12 chk 24 busy 25 bl 8, 10, 14, 16, 18, 20, 22 unused j2 power connector 1 + 185 v (+ 12 with - 2 option) 2 gnd (power) 3 gnd (logic) 4 + 5 v warning: wrong connections or reversal of the connector may cause permanent damage to the display and host interface. ordering information description part number display, driver electronics and controller ..................................................................................... ................................ apd-480m021 display, driver electronics, controller with built-in dc/dc converter .......................................................... .............
