Abstract :
The authors describe a 9-ns CMOS programmable logic device (PLD) with a standby current of 10 mu A. The circuit is a 24-pin PLD with 10 I/Os (input/outputs) and 12 dedicated inputs. Each I/O has eight summed-product terms and an output-enable control product term feeding into a programmable macrocell. Most standard 24-pin PLDs can be emulated by selectively programming the macrocell architecture bits. Bit-line precharging circuitry is used to reduce the speed degradation caused by designing for low standby current. ´Ground bounce´ is alleviated by controlling the output buffer speed. The circuit has been fabricated in a 1- mu m single-polysilicon CMOS EPROM (electrically programmable read-only memory) technology that has been optimized for speed rather than for packing density. Device and technology characteristics are summarized.<>
