P&E’s USB Multilink is an all-in-one development interface which allows a PC access to the Background Debug Mode (BDM) or JTAG interface on wide range of ARM Cortex and NXP® processor families. The Multilink is available in two different configurations, MULTILINK_ACP and MULTILINK_UNIVERSAL, which have the same functionality and vary only by their
supported MCU's. It connects between a USB port on a Windows machine and the standard debug connector on the target. The NXP microcontrollers are supported via the multiple headers located under a flip lid on the USB Multilink. Ribbon cables suitable for a variety of architectures are included.
 Watch a video overview of PEmicro's Multilink debug probes.
By using the USB Multilink, the user can take advantage of the background debug mode to halt normal processor execution and use a PC to control the processor. The user can then directly control the target’s execution, read/write registers and memory values, debug code on the processor, and program internal or external FLASH memory devices.
Multilink Features
Feature Spotlight:
PEmicro's no-cost GDB Server for ARM devices (Eclipse plug-in) includes the following powerful features:
- Real-Time Expression View
This view gives the user the ability to view variables and memory while a target ARM device is running. Sometimes the process of halting the target masks a bug. Sometimes, in order to reproduce a particular bug, the program must be kept running while being fed a particular set of data. In those cases, having the ability to view variable values as they change without halting the target is a great asset.
- OS-Aware Feature Supports FreeRTOS
The GDB server will automatically detect the presence, type, and configuration of an OS by querying the application’s symbol table for identifying characteristics. Using these discovered symbols, the debugger can traverse the kernel’s internal data structures to enumerate the available threads and their corresponding execution context. This information is then used to dynamically populate the Eclipse views as the user navigates between the threads. Additional OS support is expected to be added soon.
Supported Devices
There are two Multilink models which have the same features and only differ only by processors supported.
USB-ML-UNIVERSAL Compatible with ARM devices from many manufacturers as well as NXP's Kinetis, LPC, ColdFire V1/+V1, ColdFire V2-4, MPC55xx/56xx/57xx, HCS08, RS08, HC(S)12(X), S12Z, DSC, and STMicroelectronics' SPC5.
USB-ML-ACP Compatible with ARM devices from many manufacturers.
Supported Software
Need more features?
For a debug probe with high end features, high speed performance interface which can also supply power to the target, please see the USB Multilink FX.
For portability, stand-along programming, production programming as well as debugging capabilites, see the Cyclone and Cyclone FX stand alone programmer, test & debug interfaces.
Optional Accessory
The USB Multilink Universal includes a ribbon cable for connecting to ColdFire V2-4 targets, however the MCF5272 & MCF5206(E) devices will require a separate adapter cable (not included) to synchronize the communications signals (as these devices do not do this on-chip).

MULTILINK_UNIVERSAL and MULTILINK_ACP
Buy Specifications
The Multilink debug probe is supported by development software from P&E, NXP, and many other third parties. P&E offers two models which vary only by the devices supported. MULTILINK_ACP covers a wide variety of ARM devices. Please view P&E's ARM device resource page for a list of all supported ARM Cortex devices.
MULTILINK_UNIVERSAL covers the same as well as NXP 8/16/32 devices. Please view our available Flash Algorithms resource page for a list of available algorithms. Feature sets are the same for the MULTILINK_UNIVERSAL and MULTILINK_ACP.
