I am using Lattice and old stock NS GALs to build model railroad signals, using NS OpalJr to write and compile the equations and a TOP2004 for programming.
Lattice states "100 erase/write cycles and data retention in excess of 20 years are specified."
While I don't expect to test the 20 year figure what are the indications that the erase/write number has been exceeded? Does the unit not program and verify or does it do that but not work or work incorrectly? Has anyone exceeded these limits? If so, what were the indications?
Thanks
Al
