144-Pin Quad Flat Pack (QFP) GPIB ASIC—The TNT500X provides a single-chip IEEE 488.2 Talker/Listener application specific-integrated circuit (ASIC) and a 16-bit CPU interface to the GPIB and contains the TNT4882 and the NAT9914 ASICs. You can port existing code from these ASICs directly to the TNT500X. In addition to integrating the circuitry of the TNT4882, the TNT500X also incorporates a 3.3 V PCI core for use in IEEE 488 instrument designs that incorporate the PCI bus. The TNT500X is PCI Local Bus Specification- and Restriction of Hazardous Substances Directive (RoHS)-compliant. Additionally, the TNT500X includes a 144-pin plastic quad flat pack (QFP) surface-mount package and a 32-bit, 33 MHz PCI bus master.
