Boundary-Scan Controller Offers Wireless LAN Interface

October 22, 2012. GOEPEL electronic has announced the SFX/WSL1149-(x), which the company calls the world’s first boundary-scan controller for Wireless LAN (WLAN). The new controller is an addition to the SCANFLEX boundary-scan hardware platform.

The new boundary-scan controller series provides a triple-stream/dual-band WLAN interface for theoretical transmission speed up to 450 Mbps, enabling wireless utilization of the newest embedded system access (ESA) technologies for the testing, programming, and debugging of complex chips, boards, and entire systems.

Thomas Wenzel, managing director of GOEPEL electronic’s JTAG/boundary-scan division, said, “The wireless communication enables considerably more flexible process integration for operations such as remote debugging, centralized control of distributed test and programming systems, or resource splitting between several users in the lab as well as in the production process.”

The SFX/WSL1149-(x) controller series with integrated WLAN control is compatible with IEEE standard 802.11a/b/g/n. Additionally, the module provides USB 2.0 and Gigabit Ethernet interfaces.

The controller series includes three models of different performance classes to be configured by software, enabling TCK frequencies of up to 80 MHz. In combination with additional components of the modular SCANFLEX product range, such as the SCANFLEX TAP transceiver (SFX Transceiver) and SCANFLEX I/O modules (SFX modules), WLAN-controlled boundary-scan systems can be configured with up to eight independent parallel TAPs and up to 31 additional analog or digital functional modules. The wireless operation simplifies handling, providing benefits for remote-test, debug, and fault-diagnosis applications. On this basis, the SFX/WSL1149-(x) is able to support all technologies for embedded system access. 

The SFX/WSL1149-(x) controller series will be fully supported in the SYSTEM CASCON JTAG/boundary-scan software platform starting from version 4.6.2.
