GAL Data Sheets High-Speed E2 CMOS PLD Generic Array Logic™

GAL16VP8 GAL Data Sheets The GAL16VP8 with 64 mA drive capability and 15 ns maximum propagation delay time is ideal for Bus and Memory control appli- cations. The GAL16VP8 is manufactured using Lattice Semiconductor's advanced E2 CMOS process which combines CMOS with Electrically Erasable (E2 ) floating Gate technology. High speed erase times (<100ms) allow the devices to be reprogrammed quickly and efficiently. System bus and memory Interfaces require control Logic before driving the bus or memory Interface signals. The GAL16VP8 combines the familiar GAL16V8 architecture with bus drivers as its outputs. The generic architecture provides maximum design flex- ibility by allowing the Output Logic Macrocell (OLMC) to be con- figured by the user. The 64mA output drive eliminates the need for additional devices to provide bus driving capability. Unique test circuitry and reprogrammable cells allow complete AC, DC, and functional testing during manufacture. As a result, Lattice Semiconductor delivers 100% field programmability and function- ality of all GAL products. In addition, 100 erase/write cycles and data retention in excess of 20 years are specified. By Lattice Semiconductor Corp.
