1 - Introduction STICK User Manual
1.1 In-Circuit Communication protocol (ICC)
An In-Circuit Communication (ICC) protocol has been developed by
STMicroelectronics to minimize the hardware needed on your application board
and the number of signals used by the ST7 to communicate with the outside world.
To handle the ICC protocol, an ICC monitor is embedded in all ST7 Flash
microcontroller types. For more detailed information about the ICC Protocol, refer
to the ST7 ICC Protocol Reference Manual, available in PDF format on the MCUon-CD
CD-ROM.
The three different applications described below use the ICC protocol:
• ICP: In-Circuit Programming is an ST7 FLASH programming method using the
ICC communication protocol. ICP is used to update the entire contents of the
FLASH memory (including option bytes). For more details, see “FLASH
Programming” reference manual.
• ICT: In-Circuit Testing is a flexible method of performing production test
routines that can be easily modified and extended without affecting the content
of the FLASH program memory.
• ICD: In-Circuit Debugging is the ability to debug a FLASH device using the ICC
protocol. This ability is used in low-cost ST7 emulators such as SofTec’s
InDART emulator.
1.2 Your host PC and application board requirements
Both hardware and software components of the STICK have been designed to
work with PCs meeting the following requirements:
• One of the following operating systems: Microsoft ® Windows ® 95, 98, 2000,
Millennium, NT ® or XP.
• Intel ® Pentium (or compatible) processor with minimum speed of 133 MHz.
• Minimum RAM of 32 MB (64 MB recommended).
• 50 MB of free hard disk space to install all of the ST7 tools.
Note:
Windows ® 2000, NT ® and XP users must have administrator privileges to install the required
software.
You must design your application with an HE10 connector on your application
board to carry the ICC signals described in the next section.

STICK User Manual
1 - Introduction
1.3 ICC connector signals
Depending on the type of ST7 Flash microcontroller you are using, ICP needs a
minimum of 4 or 5 signals and up to 6 or 7 signals to be connected to the ICC
connector on the STICK Interface board.
• The following 4 or 5 signals are mandatory on the ICC connector:
- GND: Ground.
GND 1 2 ICCDATA
GND 3 4 ICCCLK
GND 5 6 ICCRESET
VDD_appli 7 8 ICCSEL_VPP
ICCOSC 9 10 GND
Figure 2: ICC connector map
- ICCDATA: During ICP activity, the application board must not drive (source
or sink) more than 1 mA of current.
- ICCCLK: During ICP activity, the application board must not drive (source
or sink) more than 1 mA of current.
- ICCRESET: During ICP activity, the application board must not drive
(source or sink) more than 5 mA of current.
- ICCSEL_VPP: The application pull-down resistor must not be lower than
10 kOhm. (Note that the ICCSEL_VPP signal doesn’t exist on the
ST72FLITE0x).
• The following 2 signals are optional:
- VDD_appli: Needed if the W1 jumper is in the VDD position (see Section
2.3 on page 9).
- ICCOSC: Safe clock. Only necessary if ICP_OPT_Disable programming
mode (see Section 2.4 on page 11) is used and if your ST7 Flash
application clock is not a square wave from 0 V to V DD (if, for example, you
use the internal RC oscillator of the ST7 Flash Microcontroller, or have a
resonator or an RC on the OSC1/OSC2 pins). In this case ICCOSC safe
clock must be connected to the OSC1 pin of the ST7 Flash microcontroller
in your application.
For more information, see the datasheet of the ST7 Flash microcontroller.

5 Reboot your PC as prompted before connecting the hardware (see Setting up
the hardware on page 9) and launching STVP7 for the first time.
2.3 Setting up the hardware
1 Connect the STICK interface board to the LPT1 port of your host PC with the
supplied parallel cable.
Note:
Be sure to use the PC parallel port cable provided with your STICK—using a longer
PC parallel port cable may cause malfunctions.
Connect the cable directly between the host PC and the STICK interface board—the insertion
of additional cables or switch boxes between the host PC and the STICK interface board may
cause malfunctions.
If a dongle (a hardware key required by some software packages) is already connected to the
PC’s parallel port, it should not interfere with STICK interface board. However, if a malfunction
of the board should occur, please remove the dongle and restart the above sequence.
2 Configure the STICK by setting W1 jumper according to your application.

Figure 3: STICK interface board component layout
The W1 jumper must be set to one of the three following positions:
- V DD : The power supply voltage of the STICK’s ICC buffer follows the
application V DD . This position allows you to work with any V DD value
allowed in the ST7 datasheet. When the jumper is in this position, you must

2 - Getting Started
connect the application V DD to pin 7 of the ICC connector. STICK uses the
application V DD as voltage reference signal, only a 10 kOhm pull-down
resistor is connected on this V DD line.
- 5V: The power supply voltage of the STICK’s ICC buffer is 5 V. You don’t
need to connect the application V DD to pin 7 of the ICC connector, but your
application must be powered by 5 V +/- 5%.
- 3.3 V: The power supply voltage of the STICK’s ICC buffer is 3.3 V. You
don’t need to connect the application V DD to pin 7 of the ICC connector, but
your application must be powered by 3.3 V +/- 5%.
3 Power on the STICK using the AC/DC power supply adaptor provided. Ensure
that the AC/DC power supply adaptor is adapted to the mains voltage and outlet
type used in your country.

ST7 Visual Programmer (or press the
button).
Figure 4: Configuration dialog box
3 From Hardware list, select STICK.
4 From Port list select PC parallel port LPT1.
5 From the Programming mode list, you must select one of the three modes.
Depending on Programming mode selected, a specific ST7 Flash Device list
will be displayed.
Selecting the correct programming mode is critical in order to program your
microcontroller. To correctly choose the Programming mode, you have to:
- Find the option byte description in your ST7 Flash microcontroller’s
datasheet.
- Check whether the ST7 is ex-factory or not. Ex-factory devices are brand
new devices with factory default options programmed.

Table 1: Determining the programming mode
To better explain the differences between the programming modes, here is a
brief description of each:
- ICP: This programming mode is for ST7 Flash devices without OSCTYPE
choice possibility in the option byte. Currently, for ST7 devices supported by
STICK, only ST72HUB is in this category. For all other ST7 devices you
have to select one of the other programming modes.
- ICP OPT Disable: This programming mode is a safe mode. It must be used
when ICP OPT Enable configuration does not work. This can be the case if
your application clock circuitry doesn’t match the previously programmed
OSCTYPE option byte selection. In this programming mode, an external
source with a square wave signal from 0 V to V DD must be applied. This
clock can be provided either by your application, or by the ICC connector
pin 9 (ICCOSC safe clock).
- ICP OPT Enable: This programming mode has to be selected if the
ST7 Flash is ex-factory, or if your application clock circuitry matches the
previously programmed OSCTYPE option byte selection. In this
programming mode, the ICCOSC safe clock from the ICC connector pin 9
is not needed.

Depending on the ST7 Flash microcontroller you choose, you be able to specify
additional protection settings—refer to STVP7’s online help.
If you do not find the name of your ST7 Flash microcontroller in this Device list, it is either
because you chose the wrong Programming mode, or your STVP7 version doesn’t support
this ST7 Flash microcontroller yet. In this latter case you have to download the latest STVP7
release from ST’s website at http://mcu.st.com.
7 Click OK to save your changes and close the Configuration window. The main
STVP7 application window is opened, as shown in Figure 5.

3 PROGRAMMING WITH STVP7
In this chapter, we explain how to perform a typical programming session.
Note that this is not the only way to program an ST7 microcontroller using STVP7;
for more information on how to use the STVP7, click the Help command in the
main menu bar.
1 Make sure you have already:
- installed STVP7 (as described in Section 2.2 on page 8),
- set up and configured the STICK interface board W1 jumper (as described
in Section 2.3 on page 9),
- set up STVP7 for the first time (as described in Section 2.4 on page 11).
2 If your microcontroller has ST7 Flash memory—either XFlash (EEPROM
technology, byte-erasable) or HDFlash (FLASH technology, sector-erasable)—
each byte must be erased before being reprogrammed.
- XFlash memory: Anything present in this memory zone is automatically
erased when you program or reprogram this type of memory. Because of
this, the Erase command is neither necessary nor available with XFlash
memory. For the same reason a Blank-Check command is not available for
XFlash memory.
- HDFlash memory: You cannot erase single bytes—only sectors. Before
programming byte(s) or sector(s) you must have erased the appropriate
sector(s). To erase, in the STVP7 main window, click on Erase>Active
sector(s) (or press the button). You can use Blank-Check command to
verify that the correct sectors are erased.
3 In the STVP7 main window, use the tab menu to select the memory area that
you wish to program (for example, PROGRAM MEMORY, DATA MEMORY or
OPTION BYTE).

Appendix A: User and Work Environment Precautions
APPENDIX A: USER AND WORK ENVIRONMENT PRECAUTIONS
The following precautions are recommended when using the programming board:
• Any tester, equipment, or tool used at any production step or for any
manipulation of semiconductor devices should have its shield connected to
ground.
• Your programming board should be placed on a conductive table top, made of
steel or clean aluminum or covered by an antistatic surface (superficial
resistivity equal to or higher than 0.5 MΩ/cm 2 ), grounded through a ground
cable (conductive cable from protected equipment to ground isolated through a
1MΩ resistor placed in series).
All manipulation of finished goods should be made at such a grounded
worktable.
• The worktable should be free of all non-antistatic plastic objects.
• An antistatic floor covering grounded through a conductive ground cable (with
serial resistor between 0.9 and 1.5 MΩ) should be used.
• It is recommended that you wear an antistatic wrist or ankle strap, connected to
the antistatic floor covering or to the grounded equipment.
• If no antistatic wrist or ankle strap is worn, before each manipulation of the
powered-on programming board, you should touch the surface of the grounded
worktable.
• It is recommended that antistatic gloves or finger coats be worn.
• It is recommended that nylon clothing be avoided while performing any
manipulation of parts.

APPENDIX B: TROUBLESHOOTING
This appendix covers some of the problems that may occur, and how to solve
them.
B.1 Test pins
The STICK board is equipped with test pins located at TP1 (see board layout in
Figure 3 on page 9). If you have problems with programming, these pins can help
you pinpoint anomalies in the ICC communication by testing or checking the ICC
signals.
Pin Signal Description
1 GND This pin is marked with a white dot.
2 Power The external power supply value can be checked
here. It is an unregulated 12 V DC power supply.
Its value should be in the range 13.5 V to 23 V
depending on the current load.
3 VCC The V CC is regulated at 5 V +/- 5%.
4 VCC_a This is the operational amplifier output that follows
the voltage value selected by the W1 jumper. It
should be equal to:
• your application V DD voltage value if W1 is in
the V DD position,
• 5 V if W1 is in the 5 V position,
• 3.3 V if W1 is in the 3.3 V position.
5 ICCSEL_VPP This signal may be at 0 V, 5 V or 12 V . This test
point is used during factory test. You do not have
to check it.

B.2 Error messages
The following sections explain the cause of some of the commoner error
messages.
B.2.1
“PC parallel port cable not connected”
Most communication failures between the host PC running STVP7 and the STICK
interface board stem from problems in the parallel port connection. To prevent
communication problems, when setting up your parallel port connection, ensure
that:
• You use the parallel cable provided with your STICK—using a longer parallel
cable may cause malfunctions.
• Connect the cable directly between the host PC and STICK interface board—
the insertion of additional cables or switch boxes between the host PC and the
interface board may cause malfunctions.
• You remove any parallel port dongles.
• Ensure LPT1 address is in the range 03BC-03BF or 0378-037F or 0278-027F.
• Ensure that “printer port LPT1” is not disabled in your PC. For example, in the
IBM ® ThinkPad, you can select “infrared printing (LPT) port on”.
B.3 “Problem on supply voltages”
When you have supply voltage problems the green LED will not come on. To find
the cause of the problem:
• Check that the AC/DC power supply adaptor is firmly connected to both the
main power supply and to the STICK interface board. To check that the main
power supply is on, disconnect ICC cable and measure the voltage at test pin 2
at location TP1 (see Test pins on page 22). This pin should have unregulated
DC value in the range 18 V to 21 V.
Note:
Ground is on TP1 pin 1 (white dot mark).
• Check that the W1 jumper is set on one of the three positions, see Section 2.2
on page 8. If it is set on the “VDD” position, check that the ICC cable is
connected properly and that your application’s VDD is connected to ICC
connector pin 7. Your application VDD must be in the range 2.4 V to 5 V. On
test pin 4 at location TP1 (see Test pins on page 22), you must have the same
voltage value that you selected with the W1 jumper.
• Check that there is 5 V on test pin 3 at location TP1 (see Test pins on page 22).
23/34

STICK User Manual
Appendix B: Troubleshooting
If you have made all of these checks and you still get the “Problem on supply
voltages” message, contact your ST distributor or sales office (see Product
Support on page 30) in order to have your STICK repaired.
B.4 “Cannot communicate with the device”
Check that:
• The ICC cable is well connected.
• You have selected the right ST7 device.
• The ICC signals are clear and within the following ranges:
- ICCDATA: This application signal must not drive more than 1 mA.
- ICCCLK: This application must not drive more than 1 mA.
- ICCRESET: This application must not drive more than 5 mA.
- ICCSEL_VPP: The pull-down resistor must not be lower than 10 kOhm.
• You have selected the right programming mode in the main menu
Configure window > programming mode list, see Section 2.3 on page 9.
Remember that:
- If you use ICP OPT Enable mode, check that your application clock
circuitry does match the CLOCK SOURCE and OSCTYPE options already
programmed in ST7 Flash microcontroller option byte. For devices out of
factory you have to check these values in datasheet. If you don’t know
these values you have to select ICP OPT Disable.
- ICP OPT Disable mode, ensure that external source clock is a square
wave signal from 0 V to VDD. If not, you have to connect ICCOSC safe
clock (ICC connector pin 9) to the OSC1 pin of the ST7Flash
microcontroller in your application
