UM0231 User manual 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. Figure 1.

Any in-circuit debugging tool that uses the ICC protocol for ST7 (10-pin ICC connection). ICD Adapter with microcontroller and 10-pin ICC connector Application board Connector is a package-specific connector that receives the ICD adapter. Application Board 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. September 2006 Rev 2 1/15 www.st.com AD-ICD ICC connector – a 10-pin HE-10 type connector that allows the connection of your in-circuit debugging tool to the microcontroller on the ICD Adapter. Application board connector/device adapter – a package specific connector that plugs into the bottom of the ICD adapter allowing the connection to the microcontroller footprint on your application board. Connectors/device adapters are provided for all available packages for the target microcontroller. About the user manuals... This document provides information about connecting the ICD adapter and to your in-circuit debugging tool and to your application board.

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. Figure 1.

Delivered from the factory, the ADICD/DS8Z-01 is configured as follows: Table 1. Default configuration of the AD-ICD/DS8Z-01 from factory Identifier on ICD adapter Configuration Purpose TP1 Fitted Allow connection for in-circuit debugging/programming TP2 Not fitted Run application in standalone mode G1 Soldered Connects tool to the microcontroller’s VDD pin (accommodate tools with a power supply follower) G2 Not soldered Connect tool’s clock signal to microcontroller’s CLKIN pin Jumpers Solder points 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. Figure 3. ICD On jumper (TP1) MB509 TP1 fitted for ICD TP2 not fitted for ICD 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 incircuit programming and debugging the microcontroller on the ICD adapter. 5/15 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. Figure 4. CLKIN solder point (G2) MB509 When the clock signal is furnished by the incircuit 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. Solder point G2 2.2 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. 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 5. RST/PA3 On jumper (TP2) MB509 TP2 fitted for standalone 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. TP1 not fitted for standalone 6/15 AD-ICD 3 3 Connecting to the application board 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. Figure 6. Connectors on the ICD Adapter 10-pin ICC connector Top 8-pin connector Bottom Table 2. Note: 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. Table 2 shows the available connectors Target MCU packages and their application connectors Package ICD Adapter Application board connector(s) DIP8 MB509 DB646 SO8 MB509 SO8, 8-pin connector DFN8 MB509 DB715 flexible adapter The DB715 flexible and associated on-application connectors for the DFN8 package are delivered with the ST7MDT10-8/DVP connection kit (see Delivery checklist).
