Scanflex boundary-scan products debut

Goepel electronic has announced the availability of several products for extended boundary-scan implementations based on its new Scanflex architecture. This wave of Scanflex products includes the SFX/PCI1149 PCI-based Scanflex boundary-scan controllers, which operate at 20, 50, or 80 MHz; Scanflex TAP transceivers, which come in 2-, 4-, 6-, and 8-TAP standard configurations as well as 2- and 4-TAP compact versions for rugged environments; and the SFX5296 Scanflex I/O module, which provides 96 parallel I/O channels.

The SFX controllers are upgradeable on the fly while residing within a host PC. They include compensation for signal propagation delay and support dynamic data synchronization of serial and parallel vectors. The TAP transceivers include resources such as 32 dynamic, parallel digital I/O channels, two analog I/O channels, three static digital I/O channels, and trigger lines. Furthermore, they feature removable TAP Interface Cards (TICs). The first available TIC—a single-ended interface with line drivers supporting TAP cable up to 1.5 m long—provides programmability for input threshold, output voltage, input and output impedance, TCK frequency, delay compensation, a relay-controlled power signal, and read-back capability of TAP output signals.

For the I/O module, each of the 96 I/O channels is individually configurable as input, output, bidirectional, or high impedance. Users can program I/O voltages in groups of 32 channels. The SFX controller, I/O modules, TAP transceiver, and TIC can be combined in any configuration with distances between controller and TAP transceiver extending to 5 m. Scanflex works with the company's System Cascon boundary-scan software environment (version 4.2.1 and up).

Starting price: $3500. Goepel electronic, www.goepel.com .
