DESCRIPTION
PIN CONFIGURATION
The GAL16V8C, at 5 ns maximum propagation delay time, com-
bines a high performance CMOS process with Electrically Eras-
able (E2) floating gate technology to provide the highest speed
performance available in the PLD market. High speed erase times
(<100ms) allow the devices to be reprogrammed quickly and ef-
ficiently.

The generic architecture provides maximum design flexibility by
allowing the Output Logic Macrocell (OLMC) to be configured by
the user. An important subset of the many architecture configu-
rations possible with the GAL16V8 are the PAL architectures
listed in the table of the macrocell description section. GAL16V8
devices are capable of emulating any of these PAL architectures
with full function/fuse map/parametric compatibility.

Unique test circuitry and reprogrammable cells allow complete
AC, DC, and functional testing during manufacture. As a result,
Lattice Semiconductor guarantees 100% field programmability
and functionality of all GAL products. In addition, 100 erase/write
cycles and data retention in excess of 20 years are guaranteed.
