Application Schematic Examples

This section includes schematic examples showing various 65510 interfaces. The schematics are broken down
into three main groups for discussion:
1) System Bus Interface
• PC/AT Notebook
• PC/Chip (F8680)
• Micro Channel
• x86 SL
• 386 SX or 386 DX
2) Display Memory Interface
• One 256Kx16 DRAM (2 CAS/ or 2 WE/)
• Four 256Kx4 DRAMs
3) Panel Interface
• F65510 Panel Interface
To design a system around the 65510, select one schematic page from each of the three groups above.
Selection of a bus interface for the VGA controller is generally dictated by the type of bus available in the system.
If performance is a concern, however, and a 386 or 486 CPU is being used, a local bus interface should be used
instead.
Selection of a memory interface depends on price and availability of the two sizes of DRAMs. Additional
considerations are the amount of board space available (one 256Kx16 will generally require less board space) and
power usage requirements (256Kx16 DRAMs have self-refresh capability so allow the 65510 and all clock inputs
to be shut down during standby mode).
Note: The circuits in this section assume the use of the F65510 (rectangular 100-pin flat pack with 0.65
mm lead pitch). The pinouts of the T65510 (square 100-pin flat pack with 0.50 mm lead pitch) are
different (the pinouts are rotated clockwise by two pins relative to the 'F' package pinouts).
