Description

The MS622424 is a high performance, full CMOS, 8K x 24, 192K-bit pipelined static memory. This device is specifically designed for use as a color look-up table in high resolution video display systems. When two of these devices are operated in parallel, the resulting system will be capable of supporting a display of 1280 x 1024 bit mapped color graphics with 13 bits per pixel in the Color Index Mode or 24 bits per pixel in the RGB Mode.

In the MS622424 Color Index Mode, three internal 8Kx8's provide 8192 simultaneous colors from a 16.7 million color palette. The palette can be partitioned into several smaller palettes thereby supporting multiple window display. In the RGB Mode, the 24-bit input can be gamma corrected on one of three gamma correction tables. The 24-bit gamma corrected value will then be presented at the output.
This device MS622424 is implemented in full CMOS for low power consumption, and is available in an 100-pin plastic or metal quad-flat-pack.
