Product Descriptions
The GAL20XV10 combines a high performance CMOS process with electrically erasable (E2) floating gate technology to provide the highest speed Exclusive-OR PLD available in the market. At 90mA maximum Icc (75mA typical Icc), the GAL20XV10 provides a substantial savings in power when compared to bipolar counterparts. E2CMOS technology offers high speed (<100ms) erase times providing the ability to reprogram, reconfigure or test the devices 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 GAL20XV10 are the PAL® architectures listed in the macrocell description section of this document. The GAL20XV10 is capable of emulating these PAL architectures with full function and parametric compatibility.
Unique test circuitry and reprogrammable cells allow complete AC, DC, and functional testing during manufacturing. As a result, Lattice Semiconductor delivers 100 percent field programmability and functionality of all GAL products. In addition, 100 erase/write cycles and data retention in excess of 20 years are specified.
