Description
The ATF1500A is a high-performance, high-density complex PLD. Built on an
advanced Flash technology, it has maximum pin-to-pin delays of 7.5 ns and supports
sequential logic operation at speeds up to 125 MHz. With 32 logic macrocells and up
to 36 inputs, it easily integrates logic from several TTL, SSI, MSI and classic PLDs.
The ATF1500A’s global input and feedback architecture simplifies logic placement
and eliminates pinout changes due to design changes.

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.
