Functional Logic Diagram(1)

Note: 1. Arrows connecting macrocells indicate direction and groupings of CASIN/CASOUT data flow.

The ATF1500A has 32 bi-directional I/O pins and four dedi-

cated input pins. Each dedicated input pin can also serve

as a global control signal: register clock, register reset or

output enable. Each of these control signals can be

selected for use individually within each macrocell.

Each of the 32 logic macrocells generates a buried feed-

back, which goes to the global bus. Each input and I/O pin

also feeds into the global bus. Because of this global bus-

ing, each of these signals is always available to all 32 mac-

rocells in the device.
