... PDSP1880, PDSP1881, PDSP1882, PDSP1883, PDSP1884 Functional Description The display's user interface is organized into five memory areas. They are accessed using the Flash Input and address lines, A3 and A4. All the listed RAMs and Registers may be read or writ- ten through the data bus. See Table „Memory Selection“ (page 9). ...

... PDSP1880, PDSP1881, PDSP1882, PDSP1883, PDSP1884 The display Blink works the same way as the Flash Enable but causes all twenty column drivers to cycle at 2.0 Hz thereby making all eight digits blink at 2.0 Hz. The Self Test function of the IC consists of two internal routines which exercise major portions of the IC and illuminates all the LEDs ...

... PDSP1880, PDSP1881, PDSP1882, PDSP1883, PDSP1884 The second routine provides a visual test of the LEDs. This is accomplished by writing checkered and inversed checkered pat- terns to the display. Each pattern is displayed for approximately 2.0 sec. During the self test function the display must not be accessed. The time needed to execute the self test function is cal- culated by multiplying the clock time by 262,144 (typical time ≈ ...

... Plas- tic band-pass filters are an inexpensive and effective way to strengthen contrast ratios. The PDSP1880 / PDSP1882 are red / high efficiency red displays and should be matched with a long wavelength pass filter in the 570 nm to 590 nm range. The PDSP1883 should be matched with a yellow-green band-pass fil- ter that peaks at 565 nm ...
