See detailed specifications on page 390. Table 1. NI 653x Specifications Overview (See page 391 for detailed specifications) Overview and Applications The NI 653x devices are high-speed, 32-bit, parallel, digital I/O interfaces for PCI, PXI, PCMCIA, and ISA. They incorporate the National Instruments DAQ-DIO ASIC, specifically designed to deliver high performance on plug-in DIO devices. The NI 653x devices perform unstrobed I/O, pattern I/O, and handshaking at speeds up to 20 MHz, or 80 Mbytes/s for 32-bit transfers (NI 6534). The NI 6534 family delivers digital I/O coupled with large onboard memory for highspeed pattern I/O at deterministic rates. Pattern I/O and Handshaking I/O With pattern I/O, you can input or output patterns under timing control of a clock signal. When using handshaking I/O to interface your NI 653x to a peripheral device, data is transferred when both the NI 653x and the peripheral are ready. See page 376 in the Digital I/O overview and page 787 in the Digital I/O tutorial for more information. BUY ONLINE! Change Detection You can program the 653x devices to acquire data when one or more user-specified digital input lines changes state. See page 377 in the Digital I/O overview and page 787 in the Digital I/O tutorial for more information. Features Data Latches and Drivers The 32 digital I/O lines are divided into four 8-bit ports. For pattern I/O or handshaking, the ports can be grouped into two 8-bit or 16-bit groups, or a single 32-bit group. When configured for output, each data line can sink or source up to 24 mA when set logic low or high, respectively. When configured as inputs, the 653x data lines are diode-terminated to dampen the input signals at TTL levels. When performing static or unstrobed I/O, you can individually configure each of the 32 I/O lines as input or output. 378 National Instruments • Tel: (800) 433-3488 • Fax: (512) 683-9300 • info@ni.com • ni.com High-Speed 32-bit Digital Pattern I/O and Handshaking Data Lines Bus Interface Internal FIFOs PCI, PXI, CPCI, PCMCIA, ISA I/O Channel EEPROM Counters and Timers Clock Selection Request Processing 20 MHz Oscillator RTSI Interface (PCI/PXI/AT only) RTSI Bus (PCI/PXI/AT only) Figure 1. NI 653x Hardware Block Diagram Messaging You can develop event-driven application programs with NI 653x devices by programming them to generate a message when conditions you specify are met. The messages can be generated when a specified number of bytes have been transferred, when a specified input pattern is matched, or when a measurement operation completes.

To improve system performance for repetitive pattern output applications, you can load your patterns into the onboard memory once and then output them repeatedly, without reloading them across the computer bus.

With NI-DAQ, the NI 6533 and NI 6534 devices are software-compatible, providing a seamless upgrade path. Sharing clocks and triggers between NI 653x and other measurement devices is also greatly simplified. To get you started with your application quickly, NI-DAQ includes numerous example programs for LabVIEW and other ADEs. DMA/ Interrupt Requests Control Lines (8) DAQ-DIO Table 2.

Using these buses, you can create synchronized systems with large numbers of digital I/O lines and systems in which digital I/O is synchronized with other types of measurements. The PXI-653x modules feature phase-lock loop (PLL) circuitry to tightly synchronize with other PLL devices.
