ScanWorks® PCI-400 Four Port JTAG Controller

Product Overview

The PCI-400 provides a sustained data throughput of 50 Mbits/second for each of four test ports. The high throughput and multiple test ports result in faster production throughput for both testing and on-board programming of flash memory. A controller-to-UUT distance of over 50 feet at the maximum TCK frequency of 50 MHz is supported to provide the flexibility needed in your development labs and manufacturing environments. UUT interface voltages from 1.8V to 5.0V provide support for the technologies you use today. The PCI-400 also supports 20 individually controllable discrete I/O signals for controlling and monitoring non-boundary-scan signals.

ScanWorks supports up to three PCI-400 controller cards in one PC. Each controller card supports two, four-port boundary-scan interface pods for a possible total of 24 test ports.

ScanWorks software provides a means for the user to map each port to the design(s) to be tested. When the tests are applied, the user can select which ports should be active.

Product Description

The PCI-400 product, Figure 1, consists of a boundary-scan controller card that installs in the PCI backplane of your PC and an interface pod with four test ports. The base PCI-400 product includes cables that support a PC-to-pod distance of ten feet and a pod-to-UUT distance of three feet at the full 50 MHz TCK frequency. The pod is powered by the controller card for distances of less than 10 feet, but requires an external power supply at distances of over 10 feet. A cable and an external power supply to extend the PC-to-pod distance to fifty feet at the full 50 MHz TCK frequency are available.

The standard package includes:

• A PCI controller card
• A four test port interface pod
• A controller cable (10 feet)
• Four pod-to-UUT cables (3 feet each)
• A power cable (10 feet)
• Four adapters to match PCI-100 style UUT connectors to PCI-400 cable connectors
• Complete documentation
