GAL20V8 High Performance EPLD Generic Array Logic
Programmable Logic Device (PLD) IC with 8 macrocells, 24-PDIP package, article number GAL20V8B-25QPNI. This device, with the article number GAL20V8B-25QPNI, features 8 macrocells and comes in a 24-PDIP package.
The GAL20V8C, at 5ns maximum Propagation delay time, combines a high performance CMOS process with Elecrically Erasable 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 efficiently.
The generic architecture provides maximum design flexibility by allowing the Output Logic Macrocell to be configured by the user.
An important subset of the many architecture configurations possible with the GAL20V8 are the PAL architectures listed in the table of the macrocell description section.
GAL20V8 devices are capable of emulating any of zthese 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 delivers 100% field programmability and functionality of all GAL products. In addition, 100 erase/write cycles and data retention in excess of 20 years are specified.
These Gals were going obsolete, but you can still buy these with limited qty, as long as own stocked, from Luna Electronic GmbH, Germany.
