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.
