• Description: Gal High-speed E2 Cmos Pld Generic Array Logic?
• Manufacturer: Lattice Semiconductor Corp.

In the Simple mode, macrocells are configured as dedicated inputs
or as dedicated, always active, combinatorial outputs.
All outputs in the simple mode have a maximum of eight product
terms that can control the logic. In addition, each output has pro-
grammable polarity.
Note: The development software configures all of the architecture control bits and checks for proper pin usage automatically.

Pins 1 and 10 are always available as data inputs into the AND
array. The center two macrocells (pins 14 & 16) cannot be used
in the input configuration.
The JEDEC fuse numbers including the UES fuses and PTD fuses
are shown on the logic diagram.
