Communication Hardware "Universal Access Device 3+" - UAD3+

Universal Access Device 3+ - UAD3+ sets new standards in the fields of high end trace and multicore/multi-target debugging

Universal Debug Engine (UDE) is a modern windows based workbench for application oriented development of the latest microcontroller architectures. It supports multicore, multi-system and high performance embedded target designs. The Universal Access Device (UAD) family describes a platform of hardware communication devices for embedded microcontroller systems which allow a highly flexible, high-performance access to the target system.

UAD3+ Debug Support TriCore, PowerPC, ARM, Cortex

The UAD3+, 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 V to 5.5 V as standard or optionally 0.8 V to 3.3 V - cover all possible applications.

The UAD3+ not only sets new standards in multicore/multi-target debugging, but also in high end real-time trace. For this application, 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 LII). 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, the UAD3+ is also ideally equipped for future tasks.

Basic Features

The UAD3+ is based on a modular concept and offers high-speed debug access to PowerPC, ARM7/9/11, Cortex-M3/M4/R4/A8/A9 and further microcontrollers MCU architectures as a modular concept. Multiple JTAG extender pods can be connected via a long cable to ensure a flexible adaptation with the target connector. The UAD3+ is designed for best class performance.
