UAD2pro

The Universal Access Device 2pro is the new smart member of the UDE® target Access Device family. It replaces the approved UAD2 and offers new enhancements in the well-known form style. It establishes a bridge to the more powerful UAD3+ using the same target adapter solution.

UAD2pro offers fastest target access via JTAG, cJTAG, DAP, DAP over CAN Physical Layer (DXCPL), SPD (Single Pin DAP) via CAN, SWD, ASC and CAN with build-in ESD protection.

The unique combination of JTAG and CAN bus, measurements of a mere 8.5 x 13 x 3.5 cm³ (W x D x H), and a robust aluminum housing, predestine the UAD2pro for mobile use in the field.

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 UAD2pro. At the same time, the full transmission bandwidth of 50 MHz serial clock is maintained.

UAD2next

The Universal Access Device2next is the powerful successor of UAD2+ and is the new all-in-one device in PLS’s UDE® target access device family. It combines the state-of-the-art debugging features of the UAD2pro with trace capabilities, which makes it ideal for efficient debugging, test and system-level analysis.

The UAD2next acts as a bridge between the base model UAD2pro and the high-end tool UAD3+. Besides a large number of powerful debug and trace interfaces, such as DAP, SWD, JTAG, cJTAG and LPD, the UAD2next also supports CAN and ASC interfaces for access to the target. Robust trace modules, which can be easily plugged in as needed, ensure a fast and efficient transfer of trace data from the target into the UAD2next.

Together with the Universal Debug Engine® (UDE) the UAD2next provides a comprehensive and powerful support even for the latest heterogeneous multi-core SoCs.

UAD3+

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+.

The UAD3+ is based on a modular concept and offers high-speed debug access to AURIX, TriCore, PowerPC, Arm7, Arm9, Arm11, Cortex-M3, Cortex-M4, Cortex-R4, Cortex-R52, Cortex-A8, Cortex-A9 and further microcontrollers MCU architectures as a modular concept.
