The Keil ULINK2 Debug Adapter connects your PC's USB port to your target system (via JTAG, SWD, or OCDS) and allows you to program and debug embedded programs on target hardware.

Only the shell is different.

Color ULINK2

Black ULINK2

 

Features

• Supports various ARM7, ARM9, Cortex-M, 8051, and C166 devices
• JTAG speed up to 10MHz
• Serial Wire Debug (SWD) support for ARM Cortex-M based devices
• Serial Wire Viewer (SWV) Data Trace for Cortex-M up to 1Mbit/s (UART mode)
• Real-Time Agent with memory R/W during execution, terminal emulation, and serial debug output
• Seamless integration with the Keil µVision IDE & Debugger
• Wide target voltage range: 2.7V - 5.5V
• USB powered (no power supply required)
• Plug-and-Play installation using standard Windows USB drivers
• Target Connectors
  • 10-pin (0.05") - Cortex Debug Connector
  • 20-pin (0.10") - ARM Standard JTAG Connector

ULINK2 may be used for:

• On-chip Debugging (using on-chip JTAG, SWD, or SWV),
• Flash Memory Programming (using user-configurable Flash programming algorithms).

Using the ULINK2 adapter together with the Keil µVision IDE/Debugger, you can easily create, download, and test embedded applications on target hardware.
