Description

The PDSP1880 (Red), PDSP1881 (Yellow), PDSP1882 (High Efficiency Red), PDSP1883 (Green), and PDSP1884 (High Efficiency Green) are eight digit, 5x7 dot matrix, alphanumeric Programmable Displays. The 0.180 inch high digits are packaged in a rugged, high quality, optically transparent,0.300 inch lead spacing, 30 pin plastic DIP.

The on-board CMOS has a built-in 128 character ROM. The PDSP1881 also has a user definable character (UDC) feature, which uses a RAM that permits storage of 16 arbitrary characters, symbols or icons that are software-definable by the user. The character ROM itself is mask programmable and easily modified by the manufacturer to provide specified custom characters.

The PDSP1881 is designed for standard microprocessor interface techniques,and is fully TTL compatible. The Clock I/O and Clock Select pins allow the user to cascade multiple display modules.
