USER GUIDE

Introduction

The VersaClock6 - 5P49V69xx family programmer board is made to ease the programming of blank 5P49V69xx parts. With the
on-board USB interface, IDT Timing Commander™ GUI can be used to communicate with the VersaClock5 family of devices in
the socket for configuration and programming. The family of VersaClock 6 devices includes the following part numbers:
5P49V6901, 5P49V6913, 5P49V6914.

Board Overview

As shown the in the following diagram, all necessary components and connections are available to test the functionality of the
configuration after the device is programmed. By installing R14 on the back of the board with a 100K resistor, the device will
be powering up in hardware select mode, in which SEL1 and SEL0 pins can be used to switch among 4 configurations that the
device supports.

Placing a Blank Chip in the Socket

When socket is open, identify the position of Pin 1 as shown in Figure 2. Align the dot of the blank device with the round dent
engraved on the corner of the socket as pointed. After placing the blank device, secure the socket cover.

Programming Steps

1. Place a blank part in the socket–Refer to Figure 2 above. With socket opened, identify pin 1 position and place a blank part
accordingly. Close the socket and secure the socket lid.

2. Plug the board into USB port –USB port provides power to the board as well as a communication channel between GUI and
the device.

3. Start Timing Commander GUI–Launch the Timing Commander GUI software. Load the proper personality file.

4. Start a new settings file or open a pre-optimized configuration file.

5. Connect to the board–Click on the chip symbol on the top-right corner of the GUI window, as shown in Figure 3 below (left).
A rectangular area in green will display (right).

C communication is established.

6. Execute “Write All” command–Double check the setting file that is open in GUI window and make sure everything is correct.
Then click on “Write-All” symbol in the green area (See Figure 3 above, right). This is a step that must be executed before OTP
programming of the device.

7. Click on OTP button in the GUI–On lower left portion of GUI window, there is a button called OTP (Figure 4: left). Click this
button to open OTP Programming dialogue window (Figure 4: right).

Figure 4. OTP Dialogue Window

In OTP dialogue window, there is a box in front of each configuration. Check the box for the configuration(s) that you want to
program. One or more configurations can be selected at the same time. If All is checked, all 4 configuration will be programmed.

After intended configuration(s) is selected, then programming the device is only one click away – click on the blue “Burn” button
will launch the programming. If one or more of the target configurations have already been burned, there will be a warning.

Once done, a completion message will pop out which indicates a successful programming:

Figure 5. Message for Successful Programming

Important: Burning irreversibly converts ones to zeroes; it is possible to go back and burn an unburned bit or bits to zero; zeroes

cannot be restored to ones. This allows revision of a burn under limited circumstances.

Loading from OTP

For loading one or more configurations from a burned part into the VC6 GUI (“load OTP”) follow these steps: Before reading back
cycle the power on the part and set the input crystal and/or clock frequencies in the GUI to those in the original configuration(s).
This must be done manually because there is no way to store this information on the part itself. If there is more than one
configuration, this step must be repeated for each one.

Connect to the part. The “OTP” button becomes enabled. The “Active” and “Configuration” indicator lights will be displayed (see

Figure 6 below), and be illuminated or dark as appropriate. The green “Active” light means that the “OTP Burned” bit (R0[7]) has

been burned. The red “Configuration” lights are illuminated as appropriate: if on, that configuration in the OTP has been burned.

Click the “OTP” button. In the OTP dialog, check the boxes of the configurations to be loaded. If you check a box corresponding
to an unburned configuration, there will be a warning (see Figure 7 below).If there are four configurations, there is an “All”
checkbox for convenience (see Figure 8 below). Click “Load”.
