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.
