The ATF1500ABV is a high performance, high density Complex PLD. Built on an advanced Flash technology, it has maximum pin to pin delays of 12 ns and supports sequential logic operation at speeds up to 90.9 MHz. With 32 logic macrocells and up to 36 inputs, it easily integrates logic from several TTL, SSI, MSI and classic PLDs. The ATF1500ABV's global input and feedback architecture simplifies logic placement and eliminates pinout changes due to design changes. (continued)
