Description

The GAL20V8C, at 5ns maximum propagation delay time, combines a high performance CMOS process with Electrically Erasable (E2) 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 (OLMC) 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 these PAL architectures with full function/fuse map/parametric compatibility.
