ULINKpro Debug and Trace Unit

The Keil ULINKpro Debug and Trace Unit connects your PC's USB port to your target system (via a JTAG, Cortex Debug, or Cortex Debug+ETM connector). It allows you to program, debug, and analyze your applications using its unique streaming trace technology.

The ULINKpro D Debug Unit has the same high debug performance, but does not support ETM Instruction Trace.

ULINKpro, together with MDK-ARM, provides extended on-the-fly debug capabilities for Cortex-M devices. You are able to control the processor, set breakpoints, and read/write memory contents, all while the processor is running at full speed. High-Speed data and instruction trace are streamed directly to your PC enabling you to analyze detailed program behaviour.

Features

• Supports ARM7, ARM9, Cortex-M0, Cortex-M1, Cortex-M3, and Cortex-M4 devices
• JTAG support for ARM7, ARM9, and Cortex-M
• Serial Wire Debug (SWD) support for Cortex-M
• Serial Wire Viewer (SWV) Data and Event Trace for Cortex-M up to 100Mbit/s (Manchester mode)
• Instruction Trace (ETM) for Cortex-M3 and Cortex-M4 up to 800Mbit/s (not supported with ULINKpro D)
• Unique Streaming Trace direct to your PC, provides unlimited trace buffer
• JTAG Clock Speed up to 50MHz
• Supports Cortex-M devices running at up to 200MHz (Devices may have Trace-Port bandwidth limitations)
• High-Speed Memory Read/Write up to 1MBytes/sec
• Seamless integration with the Keil µVision IDE & Debugger
• Wide target voltage range: 1.2V - 3.3V, 5V tolerant
• Support for 5V only devices using optional 5V Adapter
• Optional Isolation Adapter provides electrical isolation from the target system
• USB 2.0 High-Speed connection
• USB powered (no power supply required)
• Target Connectors
  • 10-pin (0.05") - Cortex Debug Connector
  • 20-pin (0.10") - ARM Standard JTAG Connector
  • 20-pin (0.05") - Cortex Debug+ETM Connector

The unique streaming trace capabilities of ULINKpro delivers sophisticated analysis features such as:

• Complete Code Coverage information about your program's execution ensures thorough application testing and verification
• Performance Analysis using the Execution Profiler and Performance Analyzer enable you to identify program bottlenecks, optimize your application, and to isolate problems
• Streaming instruction trace requires the target device to have ETM (Embedded Trace Macrocell)
