PMBus demonstration board

To show the features of the ST7 I2C working as a PMBus, a demonstration board is

available on request. Please contact the nearest ST office to get this board. The evaluation

board has an ST72F264G1 MCU that has 4 KBytes Flash memory. All PMBus

functionalities are not shown, as this evaluation board has hyperterminal interface which

requires lot of messages to be stored in program memory.

5.1

System requirements

In order to use the PMBus demonstration board with the Windows operating system. The

PC should support hyperterminal software and RS232 communication using DB9

connector.

5.2

Software setup

To configure the PC hyperterminal software, the user should follow the steps as mentioned

below.

Click on Start -> Programs -> Accessories -> Communications -> HyperTerminal

as shown below.

Figure 6.

PC hyperterminal application

Select the correct port in which RS232 (9-pin cable) is connected (refer to Section 3).

Configure the following baud rate (bits per second) in hyperterminal: File -> Properties

-> Connect to -> Configure. If the user configures any baud rate other than 38400,

then RS232 communication fails.
