DESCRIPTION
The GAL22LV10D, at 4 ns maximum propagation delay time,
provides 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 com-
bines CMOS with Electrically Erasable (E
2
) floating gate technol-
ogy. 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
functionality of all GAL products. In addition, 100 erase/write
cycles and data retention in excess of 20 years are specified.
