HD63485 - Graphic Memory Interface Controller

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.

Features

  • Drives frame buffer memory directly (IOL = 24 rnA max).
  • Generates DRAM signal: row and column addresses,RAS, CAS, OE, WE, etc.
  • High.
  • speed dot.

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.
