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.… Read more Lattice ispGAL & ispLSI
