TNT5002-AQF24

TNT5002-AQF24 is a high-performance single-chip GPIB talker/listener ASIC in a 144-pin plastic quad flat pack (QFP) surface-mount package. The NI TNT5002 contains complete NI TNT4882 and NI NAT9914/TI TMS9914A register sets. Therefore, if you are using any of these ASICs, you can port existing code directly to the TNT5002, significantly reducing software development time. The TNT5002 is ideal for use in all IEEE 488 instrument designs that incorporate the PCI bus because of the compact size of the chip, its surface-mount package, and performance enhancements, which include the HS488 high-speed protocol for GPIB transfers.

• Integrated IEEE 488.1 compliant transceivers
• Single-chip PCI-to-GPIB solution, PCI or 16-bit generic CPU interface
• Fast data transfers of more than 1.5MB/s (IEEE 488.1), more than 8MB/s (HS488)
• 32-bit/33MHz PCI bus host, 3.3 or 5V PCI signaling(3.3V core)
• Internal loop-back mode for complete in-system functional testing
• REM, listen addressed, talk addressed indicator pins
• Automatic EOS and/or new line message detection
• Built-in DMA controller in PCI mode, DMA capable in generic mode
• Programmable timer interrupt for general-purpose timing
• 32bit counter, 32B FIFO buffers data between GPIB and CPU/DMA controller
