ATF1504ASV/ATF1504ASVL

Each of the 64 macrocells generates a buried feedback

that goes to the global bus. Each input and I/O pin also

feeds into the global bus. The switch matrix in each

logic block then selects 40 individual signals from the

global bus. Each macrocell also generates a foldback

logic term that goes to a regional bus.

Cascade logic between macrocells in the ATF1504-

ASV(L) allows fast, efficient generation of complex

logic functions. The ATF1504ASV(L) contains four

such logic chains, each capable of creating sum term

logic with a fan-in of up to 40 product terms.

The ATF1504ASV(L) macrocell (see ATF1504ASV(L)

Macrocell), is flexible enough to support highly complex

logic functions operating at high speed. The macrocell

consists of five sections: product terms and product

term select multiplexer, OR/XOR/CASCADE logic, a

flip-flop, output select and enable, and logic array

inputs.
