National Instruments Packs GPIB and PCI connectivity into a Single Chip

4/9/2003 - Instrument manufacturers now can use the single-chip National Instruments TNT5002 ASIC to add GPIB connectivity to stand-alone instruments based on the PCI bus interface.

By packing GPIB and PCI connectivity as well as GPIB transceivers into one chip, the NI TNT5002 helps instrument manufacturers simplify instrument design for faster time to market. The one-chip design takes up less room on a circuit board than the traditional three or four-chip solution, and therefore makes it easier and less expensive to manufacture the instrument. The chip features a 3.3 V PCI core, supports both 3.3 V and 5 V signaling and is fully compliant with revision 2.2 of the PCI local bus specification.

Instrument manufacturers can use the NI TNT5002 with NI-Device software to develop GPIB-based instruments and devices. NI-Device delivers a powerful application programming interface that instrument manufacturers can use to create bus-independent firmware for their ANSI/IEEE Standard 488.2-1992 instruments and devices.
