The Universal Access Device3+, a further development of the already established UAD2 family, was particularly optimized for use in multicore and multi-target systems with high clock frequencies. Thanks to the flexible pod and connector designs, up to eight various cores and targets respectively can be controlled with different debug protocols. A consistent further development of the JTAG extender technology by PLS permits connection lengths of up to 5 meters to the base unit. The extenders are optionally available with galvanic electrical isolation. Furthermore, with the flexible design, the pods can also carry out tasks such as CAN interface or logic analyzer probe.
Access to the targets can take place with up to 100 MHz clock frequency optionally via various serial interfaces such as JTAG, cJTAG, Device Access Port (DAP/DAP2) or Serial Wire Debug (SWD). Synchronization during debugging of several core/targets is achieved by the UAD3+ hardware and firmware. Two different input voltage ranges - 1.6 to 5.5 Volts as standard or optionally 0.8 to 3.3 Volts - cover all possible applications.
In high end real-time trace, the highly flexible pod and connector designs ensure a simple and, at the same time, efficient support of various trace protocols (e.g. Aurora, CoreSight ETM, Nexus or OCDS L2). Here too, the distance between the trace pod on the target and the base unit may also be up to 5 meters. The recorded data can be complemented by automatically generated time stamps. With a trace memory of up to 4 GBytes, a maximal trace stream width of 32-bit and possible trace signals up to 500 MHz and 3.125 Gbit/s in serial trace, the UAD3+ is also ideally equipped for future tasks.
For debugging microcontroller boards with high-voltage components, as is common for instance with motor or inverter controls, target adapters with an electrical isolation of up to 1,000 VRMS can optionally also be used with the UAD3+.
