Cloning Directly to a Chip

You can read and clone back information to a QT3xx chip directly from your PC without involving the onboard

stand-alone memory of the QTM300CA. Here’s how....

Step 1

Hook everything up:

￿Connect the serial cable from the PC to the QTM300CA.

￿Connect the QTM300CA’s cloning cable to the target PCB, or plug a QT3xx into the onboard socket.

￿Power up the QTM300CA and, if necessary, the target PCB.

Step 2

Start QT3View on the PC:

 

￿ The PC LED should light up on the QTM300CA.

 

￿ DEV0 and DEV1 LEDs will indicate the auto-detected chip type (see page 4).

 

￿ QT3View will select the proper part tab on the screen.

Step 3

Load / Modify your Setups:

 

￿ Download the Setups from the chip to your screen using

 

the ‘Download from Chip’ button (see right) or,

 

￿ Load in a Setups file from disk

 

(this will overwrite all three configuration tabs).

 

￿ Modify the Setups parameters as desired.

 

￿ Enter the correct target operating supply voltage (see page 6) if necessary.

 

￿ Enter the total burst length (see page 6) if necessary.

 

￿ Save the Setups to disk if desired (saves all three tabs into one file).

Step 4

Clone the Setups to the chip:

 

￿ Upload Setups to the chip from the current tab

 

using the ‘Upload to Chip’ button (see right).

 

￿ QT3View will display the success or failure of the clone process in the

 

“Data Transfer Status Display” at the left of the screen (the PROG LED does not

 

work in this mode).

￿Remove the chip and install another and repeat this Step 4, -or-

￿Remove the clone cable and connect to another target PCB and repeat this Step 4.

Refer to the device data sheet and the QT3View help file for more information on Setup issues.
