AD-ICD in-circuit debugging adapter
Introduction
The In-circuit debugging adapter (AD-ICD/DS8Z-01) makes it possible to debug an
application while it runs on an ST7FLiteUS microcontroller with any in-circuit debugging
(ICD) tool that uses the In-Circuit Communication (ICC) protocol for ST7.
In-circuit debugging with ICC protocol and 10-pin ICC connection requires the use of a
minimum of 4 pins on the target ST7 microcontroller. This constitutes an important
imposition on the limited pin resources of low pin count microcontrollers such as the
ST7FLiteUS (available in DIP8, SO8 and DFN8 packages).
To allow you to take full advantage of the available pins on the target device for your
application, the AD-ICD adapter uses a variant of the target microcontroller with additional
pins for in-circuit debugging. The additional pins allow the connections required for in-circuit
debugging so that none of the pins used as I/Os on the standard target microcontroller need
be used for ICD.
The ICD Adapter connects to your application board in place of the target microcontroller
and to any in-circuit debugging tool via a 10-pin ICC connector. For connection to the user
application board, the ICD Adapter can be used with connectors/device adapters for all
available packages of the target MCU (DIP8, SO8, DFN8). These connectors/device
adapters are to be installed on the MCU footprint in place of the target device.

1 Delivery checklist
The ICD Adapter for the ST7FLITEUS is delivered in an ICD Adapter kit (AD-ICD/DS8Z-01)
for use with any tool capable of in-circuit debugging via 10-pin ICC connection. It is also
delivered with the ST7MDT10-EMU3 emulator.
The kit’s components include accessories for SO8 and DIP8 packages (refer to
Figure 1 ):
1. ICD Adapter (MB509) with 10-pin ICC connector and ST7FLiteUS microcontroller.
2. Device adapter (DB646) for target devices in DIP8 package.
3. On-application connector (8-pin header) for target devices in SO8 package.
To connect to application boards when in-circuit debugging applications for devices in DFN8
package, users must also order the ST7MDT10-8/DVP, which includes:
4. Device adapter (DB715), on-application connector (a) and male-male connector (b) for
target devices in DFN8 package.

2 Configuring the ICD adapter
The following sections provide instructions about configuring your ICD adapter for In-circuit
debugging
or to Run the application in standalone mode . Delivered from the factory, the AD-
ICD/DS8Z-01 is configured as follows:
Caution: When configuring the ICD adapter, make sure that the ICD tool and application board (if
connected to the adapter) are powered off.
2.1 In-circuit debugging
ICD On jumper (TP1)
When in-circuit debugging the target application via the 10-pin ICC connection, the ICD On
jumper (TP1) must be fitted to allow the interface with an in-circuit debugging tool and the
host PC. During in-circuit debugging, the
RST/PA3 On jumper (TP2) must not be fitted.
Table 1. Default configuration of the AD-ICD/DS8Z-01 from factory

Figure 3. ICD On jumper (TP1)
To set the ICD On jumper (TP1):
1. Make sure the in-circuit debugging tool
and the application are powered off.
2. Place the jumper on TP1 as shown in
Figure 3 .
3. Connect to and power on the in-circuit
debugging tool and application board.
Refer to the on-line help of your integrated
development environment/debugging
software for further information about in-
circuit programming and debugging the
microcontroller on the ICD adapter.

2 Configuring the ICD adapter AD-ICD

CLKIN solder point (G2)
Your in-circuit debugging tool can provide the clock signal for initiating in-circuit
communication with the microcontroller on the ICD adapter. To do this, you must complete
the connection with a drop of solder on the CLKIN solder point (G2) shown in
Figure 4 .
2.2 Run the application in standalone mode
Once the microcontroller on the ICD adapter has been programmed during an in-circuit
debugging or in-circuit programming session, it can run the application in place of the target
microcontroller without being connected to an in-circuit debugging tool or the host PC.
Although in a 16-pin package, the ST7FLITEUSICD executes the application as a
ST7FLITEUS variant in 8-pin package would.
Figure 4. CLKIN solder point (G2)
When the solder drop is placed on the
CLKIN solder point (G2), pin PA5 is relayed
to CLKIN on the ICC connector. PA5 is not
available for the application.
When the clock signal is furnished by the in-
circuit debugging tool, use the Option Bytes
Disabled mode to start the in-circuit
debugging session. For further information
about this mode refer to the online help of
your integrated development environment or
debugging software.

Figure 5. RST/PA3 On jumper (TP2)
To run the application in standalone mode,
the RST/PA3 On jumper (TP2) must be fitted
and the
ICD On jumper (TP1) must not be
fitted.
In standalone mode, the RST/PA3 pin can
only be used for reset. PA3 is not available.

3 Connecting to the application board
This chapter describes the physical connection of the ICD adapter to your in-circuit
debugging tool and to your application board.
Note: The DB715 flexible and associated on-application connectors for the DFN8 package are
delivered with the ST7MDT10-8/DVP connection kit (see Delivery checklist).
The following sections show connection illustrations for each supported package type:
● Connection for DIP8 microcontroller package on page 8
● Connection for SO8 microcontroller package on page 9

Figure 6. Connectors on the ICD Adapter
The ICD Adapter (MB509) connects to
your in-circuit debugging tool via the
10-pin ICC connector on the top of the
adapter. It connects to the connector
installed on you application board via
an 8-pin connector on the bottom of
the adapter (see
Figure 6 ).
To use the ICD Adapter you will have
to solder the appropriate package
specific connector to your application
board in place of your target
ST7LiteUS microcontroller.
