JT 2154 - JTAG Technologies Inc.
The JT 2154 is an experiment board based on National Semiconductor’s STA111 device, aimed at users looking to utilise addressable bridge/multiplexors within their designs, and thus set-up ‘system level’ JTAG access. The unit can also be used in semi-permanent installations to expand the TAP (Test Access Port) count on JTAG Technologies controllers in order to address highly segmented designs. Built-in support for ScanBridge-type devices within ProVision allows easy set-up of TAP assignments and device addressing.
