3.3 V ORCA FPGAs

The gate density for the Field Programmable gate array (FPGA) has grown rapidly for the past year. Today 40,000 usable gates is a reality and the density will continue to grow in the near future. Unfortunately, the power consumption also grows with the gate density. This coupled with the 3.3 V system applications such as PCMCIA calls for the need of an FPGA in 3.3 V. This paper describes the design challenges in implementing the 3.3 V Optimized Reconfigurable Cell Array (ORCA) FPGAs known as the 2T series
