ATF1500A/AL
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.
