the MB89322A to the 8080. The MB89321A1MB89322A refresh the display by buffering information from main memory using thirty-three internal registers and keeping track of the display position of the screen. Both devices are designed to allow simple interfacing to most raster scan CRTs with a minimum of external hardware and software overhead.DESCRIPTION
The MB89321 A/MB89322A Programmable CRT Controllers are single chip CMOS devices used to interface CRT raster scan displays with microcomputer systems. Both devices operate on a single +5 V power supply and have TTL-compatible I/O. The MB89321A interfaces to 6800 family microprocessors; the MB89322A to the 8080.
