NI TNT5002-AQF24 is an IEEE 488.2 talker/listener ASIC for instrument-control designs. NI describes a 144-pin plastic QFP/PQFP surface-mount device; the LCDChip package register lists 144-BQFP, which requires footprint confirmation.
Technical information is based on NI TNT500X product information and the TNT5002/4 technical reference manual. Confirm the exact ordering code and controlled drawings before design release.
The TNT5002 combines an IEEE 488 GPIB interface with selectable TNT4882-compatible and NAT9914-compatible register sets. Its host connection may be a PCI bus-master interface or a generic I/O interface, selected by the MODE input. The PCI implementation includes a 3.3 V PCI core and supports a 32-bit, 33 MHz PCI bus.
Combines talker/listener logic and bus transceivers for IEEE 488 instrument designs.
Supports PCI or generic I/O designs, subject to mode-specific pin assignments.
Provides 4882 and 9914 register-set modes for migration planning.
PCI4882 mode provides separate GPIB and DMA FIFOs for bus transfers.
IEEE 488.1 bus signaling with IEEE 488.2 talker/listener application support.
PCI4882, GEN4882, PCI9914 and GEN9914.
IEEE 1149.1 JTAG test interface and status-indicator outputs.
GPIB circuitry can use an external clock or, in PCI mode, PCI_CLK under the documented control input.
The LCDChip package registry calls this footprint 144-BQFP. NI calls TNT5002-AQF24 a 144-pin plastic QFP/PQFP surface-mount device. These labels are not treated as equivalent without a dimensional drawing and pin-one comparison.

The registered JPG is pending: the local file is absent and the production image currently returns HTTP 404. Resolve the BQFP-versus-PQFP designation before release.
NI's TNT5002/4 technical reference manual identifies these functional signals; use its full pin map for physical pin numbers and the chosen host mode.
Eight GPIB command/data lines.
GPIB interface-management signals.
GPIB three-wire handshake signals.
Selects PCI versus generic host-interface pin functions at design time.
Selects the documented clock source for GPIB circuitry in applicable modes.
IEEE 1149.1 JTAG test signals.

Mode-dependent values are not universal device limits. Confirm electrical limits and timing in the controlled NI reference for the selected mode.
NI describes the TNT500X as incorporating functions associated with the TNT4882 and NAT9914 ASICs, enabling code-porting evaluation. That does not establish pin, package or electrical interchangeability. Before considering an alternative, compare the selected 4882/9914 register set, PCI versus generic host mode, GPIB transceiver behavior, clocks, voltage, temperature rating, compliance, and the exact package drawing. No LCDChip internal substitute is asserted without an exact catalog match.
NI identifies TNT5002-AQF24 as the orderable member of its TNT500X GPIB ASIC family. NI's TNT5002/4 technical reference manual is the engineering source for operating modes and signal functions. Refer to current manufacturer-controlled documents for design acceptance and compliance declarations.

Engineering evaluation of TNT4882/9914 software migration.
Match device marking and documentation to the exact TNT5002-AQF24 ordering code. Confirm manufacturer traceability, packaging condition and the latest applicable NI compliance documentation. NI lists the orderable part as RoHS-compliant; verify the documentation required for the receiving program.
Yes, according to NI, but MODE selects different host-interface pin assignments and is not intended to change dynamically.
No. The catalog registry and NI use different package labels. Compare the controlled mechanical drawing and footprint before layout or release.
Not established. NI discusses code migration, while hardware compatibility still requires a full mode, pinout and electrical review.
This page is a selection aid, not a substitute for NI's controlled manual. The registered 144-BQFP package name has not been reconciled to NI's PQFP description, and the registered package image is unavailable. Hold final footprint and production decisions until these items are resolved.
