USB Multilink Universal & USB Multilink Universal FX - Technical Summary

Universal/Universal FX Pin-Outs, Ports F-H

The user can take advantage of debug modes to halt normal processor execution and use a computer 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.

the TVCC pin. This removes the need for an external power supply for systems requiring 200mA of current or less.

Usage

The USB Multilink Universal and Universal FX can communicate with Kinetis (including L-Series devices), Qorivva MPC5xxx,

ColdFire V1/V2/V3/V4, Power Architecture PX Series, RS08, HCS08, HC(S)12(X), S12Z, DSC, and HC16/683xx

(FX only)

microprocessors by connecting a ribbon cable between the target's debug header and one of the multiple ports on the Multilink.

Do not attempt to use multiple ports at once, as this may damage both the target processors as well as the Multilink.

The USB Multilink Universal and Universal FX interfaces will work with targets whose processor power supply is in the range of

1.8V to 5V.

On the Universal FX, if the user wishes to provide power to the target, the JP10 Jumper

and select the voltage. A shunt at position 1-2 enables 5V, while a shunt at position 2-3 enables 3.3V. The USB Multilink

Universal and Universal FX have a female type B USB connector. Use a Type A to Type B male-to-male USB cable to connect

the interface to the PC.

Universal/Universal FX Header Layout (Pin 1 Highlighted)

There are two LEDs on the Multilink interface. The blue LED indicates that the interface is powered and running. The yellow

LED indicates that target power has been detected.

Note: If connecting to a ColdFire V2-4 processor which requires synchronous communication, such as the

MCF5272 and MCF5206(E), a CABLE-CF-ADAPTER (sold separately) is required.

Note: To avoid improper connections, the red stripe of the ribbon cable should always be oriented towards Pin 1,

both on the Multilink port and the target processor header.

The USB Multilink Universal and Universal FX are USB devices. If a USB Hub is used, it must be a self-powered hub (i.e. with

its own power supply). By default, the USB protocol used is USB 2.0.
