Description
The GAL22LV10D, at 4 ns maximum propagation delay time, pro-
vides the highest speed performance available in the PLD market.
The GAL22LV10C can interface with both 3.3V and 5V signal levels.
The GAL22LV10 is manufactured using Lattice Semiconductor's
advanced 3.3V E
2
CMOS process, which combines CMOS with
Electrically Erasable (E
2
) floating gate technology. High speed erase
times (<100ms) allow the devices to be reprogrammed quickly and
efficiently.
The generic architecture provides maximum design flexibility by
allowing the Output Logic Macrocell (OLMC) to be configured by
the user.
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.
