HD63485 Datasheet | Hitachi Semiconductor

HD63485-------- Description The HD63485 LSI belongs to the ACRTC (advanced CRT controller) family. It provides memory access control to frame buffers for graphic display and drawing. Incorporating bus driver circuits and a DRAM (dynamic RAM) interface, the GMIC allows direct connection to DRAMs with no external circuits. Its main function includes address data latch, DRAM row and column address multi- plexing, supplying RAS, CAS, OE, WE, and other signals, and generating the 2CLK signal for the ACRTC. Using the Hi- BiCMOS process, the HD63485 achieves high speed memory access with low power dissipation. Type of Products Part No. HD63485PS- 32 HD63485PS- 48 HD63485PS-64 HD63485CP-32...
