A 3.3-V programmable logic device that addresses low power supply and interface trends

摘要

This paper discusses a 3.3 V programmable logic device family which provides up to 130 Kgates. It blends a multi-dimensional interconnect scheme, logic array block approach consisting of 6,656 logic elements and circuit techniques to address low power supply and interface trends. It is designed on a 0.35 /spl mu/m triple metal-dual oxide process to operate in a 3.3 V only, 5 V only or 3.3 V-5 V systems. Under worst case operating conditions it was observed to have a typical system operating frequency of 90 MHz. The EPF10K50V is the first member of the second-generation FLEX 10K family.
