JT 2154 ScanBridge

Desktop
Three secondary-TAPs with LED activity indicators
Standard JTAG 10-way IDC connector
Features industry standard STA111 chip
64 address options via on board DIP switch

The JT 2154 is an experiment board based on National Semiconductor’s STA111 ScanBridge device, aimed at users looking to utilise addressable TAP (Test Access Port) bridges/multiplexors within their designs to set-up ‘system level’ JTAG access. The unit can also be used in semi-permanent installations to expand the TAP 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.
