Benefits
Interface
Synchronous
Better interaction between memory and system without wait-state of
asynchronous DRAM.
High speed vertical and horizontal drawing.
High operation frequency allows performance gain for SCROLL, FILL,
and BitBLT.
Pseudo-infinite row length by on-chip interleaving operation.
Hidden row activation and precharge.
High speed vertical and horizontal drawing.
High speed vertical and horizontal drawing
Programmable burst of 1,2,4,8 and full page transfer per column
addresses.
Programmable burst of 1,2,4,8 and full page transfer per column
addresses.
Switch to burst length of 1 at write without MRS
Sequential & Interleave Compatible with Intel and Motorola CPU based system.
2,3
Programmable CAS latency.
High speed FILL, CLEAR, Text with color registers.
Maximum 32 byte data transfers (e.g. for 8bpp : 32 pixels) with plane
and byte masking functions.
1 ea.
A and B bank share.
1 ea.
Write-per-bit capability (bit plane masking). A and B banks share.
DQM0-3
