Lattice ispGAL & ispLSI

The ispGAL 16Z8 was introduced by Lattice in 1986, one year after introduction of the GAL 16V8. ispGAL, is short for In-System re-Programmable GENERIC ARRAY LOGIC. It is only listed in the 1988 Data Book and was soon replaced by the ispGAL 22V10.

The GAL 16V8 is a direct replacement for most 20 pin PALs. This CMOS device was the first electrically erasable programmable logic device and has been produced until 2010.

pDS (pLSI/ispLSI Development System) Software

The pDS Software provides Boolean Entry and Fitting only. Partitioning of the logic into the individual GLBs (Generic Logic Block) has to be done manually.
