High-Performance Boundary-Scan Test and In-System Programming Controller

Boundary-scan has proven itself time and again to be a versatile interface for structural test, embedded functional test, built-in self test (BIST), software debug, and in-system programming. Supporting such diverse applications requires a controller with high performance specifications and extended features.

The PCI-1149.1/Turbo is a high-performance boundary-scan controller for multi-TAP (Test Access Port) and concurrent JTAG test and in-system programming. When combined with a ScanTAP™ intelligent pod, the PCI-1149.1/Turbo offers up to 80 MHz clock rates on 4 or 8 TAPs with features such as external write strobe, direct programming, and analog voltage measurement.


  • High-performance 32-bit PCI JTAG controller.
  • Multi-TAP and/or concurrent (gang) testing and In-System Programming (ISP) on up to 8 UUTs for high volume test.
  • Works with the ScanTAP™ series of intelligent pods for up to 8 TAPs.
  • Up to 30 feet of extended distance from the PC to the pod—no TAP extenders required.
  • User-programmable JTAG TCK rate up to 80 MHz.
  • External write strobe and Ready/Busy signaling for increased Flash programming performance.
  • 16 inputs and 16 outputs of programmable parallel I/O.
  • Works with Microsoft Windows® and Linux operating systems (32-bit and 64-bit).

High Performance, Versatility

The Corelis PCI-1149.1/Turbo JTAG controller is fully compliant with the IEEE Standard 1149.1 for test access. The controller fits in a PCI slot on the host PC and connects by SCSI-II cable through a ScanTAP pod to up to 8 TAP connectors on any JTAG-based target system. Support for both multi-TAP and concurrent (gang) test execution with in-system programming, voltage measurement capabilities, and integrated serial interfaces on each TAP connector make the PCI-1149.1/Turbo with ScanTAP ideal for all boundary-scan and serial bus programming applications.

Scan Function Library

For applications that require a low-level interface or integration with third-party software, Corelis offers a Scan Function Library (SFL). The SFL is provided as a 32-bit DLL for Microsoft Windows and provides all functions necessary to operate the JTAG port and send or receive JTAG instructions and data to the target system. Users can incorporate the drivers in their own application software or integrate the SFL with third-party systems such as National Instruments LabVIEW, National Instruments TestStand, and Keysight VEE.

Boundary-Scan Test

Use boundary-scan to test, debug, and verify hardware through all phases of a product’s life cycle—from development through production and into the field.

JTAG Embedded Test

Control a microprocessor through the JTAG debug port to run functional tests, without requiring boot code.

In-System Programming (ISP)

Read, erase, program, and verify Flash Memories, serial PROMs, CPLDs, FPGAs, and other programmable devices directly within a circuit or system design.

High Volume Production

Run concurrent tests and ISP on up to 8 UUTs with ScanExpress Runner™ Gang Edition.


  • Save time at test stations with high performance—up to 80 MHz on all TAPs for lightning fast test and in-system-programming.
  • Reduce costs associated with fixtures; ScanTAP intelligent pods can connect to up to 8 TAPs for multi-TAP and/or gang operation.
  • Compatible with the complete ScanExpress™ family of boundary-scan and JTAG embedded test products.

Software Support ScanExpress Tools

Corelis offers a complete family of boundary-scan test, JTAG embedded test, and in-system programming tools—all fully compatible and with the PCIe-1149.1 advanced features.
