1 INTRODUCTION
The ST7SB socket board complements any ST7 programming tool that is
equipped for in-circuit programming (ICP) via a 10-pin ICC cable. For these
programming tools and emulators, the socket board provides the sockets required
to program ST7 FLASH microcontrollers without having to install them on an
application board.
Your socket board uses your programming tool ’s ICC connection and connects via
the ICC cable (See
Section 3.2.1 ). The programming tool, then serves as the
hardware interface with your host PC running ST7 Visual Programmer (STVP7).
When using the ST7-STICK, users have the additional possibility of connecting
their socket board directly to the ST7-STICK using the female HE10-connector on
the bottom of the socket board (See
Section 3.2.2 ).
ST7SBxx socket boards are each designed to support the programming of a family
of ST7 microcontrollers (a typical example is shown in
Figure 1 ). For this reason,
the layout of each type of socket board varies depending on the types of
programming sockets required to support a microcontroller family. However, the
general configuration and connection procedures explained here, remain the same
for all socket boards.

Note: The ST7SBxx socket board is meant to program small numbers of microcontrollers (i.e.
prototypes in the development stage). For mass production programming, we recommend
using the appropriate gang, or automated programmer.

2 DELIVERY CHECK LIST
Your ST7SBxx socket board (see Figure 1 ) is delivered with one power supply.
The number and types of programming sockets will vary from one version to
another depending on the available packages for the ST7 family of devices that
your socket board supports. The version of your socket board is determined by the
ordering code that you have specified.
All the connection cables you will need to connect to your PC are provided with the
programming tool that you are using to connect to your PC.

3 CONFIGURING AND CONNECTING TO YOUR SOCKET BOARD
This chapter tells you how to set up and connect to your socket board for
programming. It includes how to:
•
Configure the power supply for your ST7
• Connect to the socket board
3.1 Configure the power supply for your ST7
Your socket board allows you to configure the power supply (VDD) for your ST7.
As standard options, you can choose between 3.3V and 5V by changing the
position of the VDD jumper. In addition, you can configure other VDD supported by
your ST7 by installing the appropriate resistors in series in the area labeled
OTHER on your socket board.
Caution: When choosing the VDD, you must ensure that the selected voltage is supported by both your
ST7 and by the programming tool that you are using to connect the socket board to your host
PC. Refer to your ST7xxx Datasheet and the user manual for your programing board for more
information.
Configure for 3.3V or 5V
To select 3.3V or 5V, simply set the VDD jumper to the appropriate position, as
shown in
Figure 2 .

Configure for other VDD
To configure your socket board to use a VDD other than 3.3V or 5V, you will have
to calculate the required serial resistance and install the necessary resistors in the
area labelled OTHER that is provided on your socket board. To do this:
1Calculate the serial resistance for the voltage you want, using the formula:
RVDD.OTHER = (50 / VVDD.OTHER) -10
RVDD.OTHER : is the serial resistance in KΩ to be installed in the OTHER area on
the socket board.
VVDD.OTHER : is the desired VDD voltage.
2Install the necessary resistors in the OTHER area on the socket board.
Figure 3
shows one possible solution for the example in Step 1.
3Set the VDD jumper to the OTHER position (see
Figure 2 ).
Figure 3: Installing serial resistors
Example to obtain a VVDD.OTHER of 4V:
RVDD.OTHER = (50 / 4) - 10 = 2.5 KΩ

3.2 Connect to the socket board
All ST7 programming tools that use a 10-pin ICC cable (including the ST7-STICK)
can be connected to the HE-10 type ICC connector on top of your socket board.
However, when using the ST7-STICK you can also connect via the Female HE10
connector on the bottom of your Socket board.
The following sections tell you how to setup your socket board when:
•
Connecting via the ICC cable (all programmers and emulators)
• Connecting via the female HE10 connector (ST7-STICK only)
3.2.1 Connecting via the ICC cable
To connect to your socket board via ICC cable:
1Plug the ICC cable into the HE-10 connectors on your programming tool and
your socket board. The ICC cable is provided with your programming tool .
2Set both POWER jumpers to the 2 position, as shown in
Figure 4 , inset B .
3Connect the power supply for both the socket board and the programming tool.
Once connected, the green Power LED should light up and remain lit.
You are ready to program your ST7 from the STVP7 interface on your host PC.

3.2.2 Connecting via the female HE10 connector
When using this connection, power for the socket board can be provided by its
power supply, or by your ST7-STICK. However, you must configure the POWER
jumpers appropriately.
Note: No matter which option you choose for powering your socket board, your ST7-STICK’s power
supply must be connected, as it cannot be powered by the socket board.
To connect to the female HE10 connector on your socket board:
1Plug the male HE10 connector on the ST7-STICK, into the female HE10
connector on the bottom of your socket board.
2Choose a power supply configuration (i.e. both tools powered by the ST7-
STICK, or each tool powered by its own power supply) and set the POWER
jumpers on your socket board to the appropriate position:
-Set POWER to 1if the socket board is supplied by the ST7-STICK, as
shown in
Figure 4 , inset A .
-Set POWER to 2if the socket board is supplied by its own power supply as
shown in
Figure 4 , inset B .
3Plug in the appropriate power supply, or power supplies. Once connected, the
green Power LED should light up and remain lit.
You are ready to program your ST7 from the STVP7 interface on your host PC.
