When you connect the power supply be sure to: 1. Ensure that the operating voltage (110 Volts/220 Volts), which is indicated on the label on the power supply, matches your mains supply. Contact your dealer if this voltage does not correspond to your mains supply. Connect the external power supply provided with the emulator to the rear panel of the ST Micro Connect box using the 5-pin DIN connector. Plug the power supply into the mains using the supply cable provided. AC voltage: 100 V to 240 V Frequency: 50 to 60 Hz 2. 3. 4.3.4 Output and Input triggers Your ST Micro Connect box has two output triggers (OUT1, OUT2), and one input trigger (IN), which are available via SUB-click connectors located on the front panel (see Figure 17). Both input and output signals are at TTL level. Advanced Breakpoints in STVD7, allow you to define an event based on input signals (see also Section 4.4.3 on page 22), and program signals to the output triggers. The following trigger output modes (schematically represented in Figure 20) are supported: ● ● ● ● Output a pulse—where a signal of value 1 is sent during exactly one memory cycle. Toggle—where the signal value is changed from 0 to 1 or from 1 to 0. Set the output high —where the output signal is set equal to 1. Set the output low—where the output signal is set equal to 0. Several examples of how to program Advanced Breakpoints to control the sending of signals to the output triggers are given in STVD7’s online help and user manual. 19/39 Emulation configuration Figure 20.

This design is based on: 1. 2. an interchangeable, target emulation board (TEB) that is specific to the ST7 or family of ST7s that you want to emulate. a common emulation board (CEB) and a dedicated emulation board (DEB) that are common to all ST7. The TEB connects to the DEB, which is housed in your EMU3 probe. The probe connects to your application board during emulation via a flex adapter and socket. In addition, an analyzer input connector allows the connection of external devices, or input signals from your application hardware. More information about these connections is provided in the ST7xxxx-EMU3 Probe User Guide. Figure 21. EMU3 probe Micro Connect ports EMU3 probe Analyzer input connector Access for flex adapter for connection to the application board 4.4.1 Target emulation board (TEB) To reconfigure your EMU3 probe to emulate another ST7 or family of ST7s, simply install the appropriate target emulation board (TEB) in the EMU3 probe. TEBs can be ordered independently. For information about the TEB to choose, refer to the ST Product and Tool Selection Guide. Installing and changing the TEB is described in detail in the ST7xxxxEMU3 Probe User Guide provided with your probe. 4.4.2 Application board connectors Connectors on the TEB allow you to connect your probe to your application board, using the appropriate flex adapter and socket. How you connect your EMU3 probe to your application board depends on the ST7 and its package. Different application connectors are provided with your emulator, depending on the MCUs supported by its probe. For a list of connectors provided with your probe and detailed installation instructions, refer to the ST7xxxx-EMU3 Probe User Guide provided with your probe. 21/39 Emulation configuration ST7-EMU3 series emulator 4.4.3 Analyzer input connector An analyzer input connector is located on the EMU3 probe as shown in Figure 21. The analyzer input connector allows you to use 8 external input signals (TTL level). The connector has nine pins—one ground pin (the right-most pin) and eight input signal pins (18), as shown in Figure 22. Figure 22. Analyzer probe input connections 87654321 GND 1 ground pin (GND) and 8 male input pins (1-8) A specially-adapted 9-wire cable is included to connect your application or an external device (such as an oscilloscope or multi-meter) to these inlets. Each wire is color-coded as summarized in Table 2: Table 2. Analyzer input pin-wire correspondence Analyzer input pin Ground (GND) 1 2 3 4 5 6 7 8 Wire color Black Brown Red Orange Yellow Green Blue Purple Grey 4.4.4 Application power supply follower Your emulator is equipped with an automatic power supply follower, which converts your application power to the range supported by the emulator. The emulator’s internal power supply regulator supports a VDD voltage up to 5.5 V. The lower limit of the range depends on the ST7 you are emulating. For more information, refer to your ST7xxxx Datasheet. If your application’s voltage lies outside of the range supported by your emulator or your ST7, the emulator’s power supply follower will convert the voltage to within the appropriate range – for example, even if the application voltage is 6 V, it will be limited by the emulator to 5.5 V. 22/39 ST7-EMU3 series emulator Emulation configuration 4.5 Sharing ST Micro Connect with EMU3 probe and ICC Add-on Your ST Micro Connect box is the main component for using both the EMU3 probe for emulation and the ICC Add-on for in-circuit communication. You can use the same ST Micro Connect box in both cases if you follow these guidelines: ● ● Use only one connection at a time, either the EMU3 probe or ICC add-on connection. When switching from the EMU3 probe to the ICC Add-on, follow the procedure below. Switch off the application board. Switch off the ST Micro Connect box. Disconnect the EMU3 probe from the application board socket. Place your ST7 in its socket on the application board. Plug the ICC cable into the HE10 connector on your application board. Switch on the ST Micro Connect box. Switch on the application board. Switching from EMU3 probe configuration to ICC Add-on configuration: 1. 2. 3. 4. 5. 6. 7. 4.6 Automatic firmware updates The ST Micro Connect box and EMU3 probe have been designed so that their respective firmware is updated automatically. Your emulator firmware may require updating if you have changed the TEB or if you update your version of STVD7. The update is done automatically if you start a debugging session and STVD7 detects an old firmware version. For more information refer to the STVD7 User Manual. 4.7 4.7.1 Emulator functional limitations and discrepancies Voltage limitation for I2C peripheral For all target ST7s, if the I2C peripheral is used, you must limit the pull-up resistor to 1.5 kOhms. 4.7.2 Memory emulation limitation The memory zones listed below can only be configured as RAM, ROM, Non-existent memory (NEM), vectors or stack. ● ● from 0x00E0 to 0x00FF from 0xEBE0 to 0xFFE0 4.7.3 Limitations and discrepancies for specific MCUs or families of MCUs Specific MCUs or families of MCUs may be subject to emulation limitations or discrepancies. You will find information about these specific limitations in STVD7’s Discrepancies window. For more information refer to the STVD7 User Manual. 23/39 In-circuit communication configuration ST7-EMU3 series emulator 5 In-circuit communication configuration In the in-circuit communication configuration, the ST7-EMU3 emulator provides the capability to program your application to your microcontroller and to debug your application as it runs on your ST7. The following sections provide information about: ● ● ● ● Section 5.1 – the system architecture Section 5.2 – ICC connection requirements Section 5.3 – ICC Add-on features Section 5.4 – the ST Micro Connect boxes’ dual configuration capability 5.1 System architecture and development features The ST7-EMU3 emulator comes with an in-circuit communication (ICC) Add-on. This connection device allows users to take advantage of the ICC protocol for in-circuit programming (ICP) and debugging (ICD) on ST7s with XFLASH or HDFLASH memory. In conjunction with ST7 Visual Pr-ogrammer (STVP7) and ST7 Visual Develop (STVD7) software, this device makes it possible to program your application software to the ST7 on your application board and then debug your application while it runs on your ST7 (see Figure 23). In the in-circuit communication configuration, the ICC Add-on serves as the hardware interface for connecting your ST Micro Connect box to the ST7 on your application board. During application development, STVD7 software running on your PC provides an integrated development environment that allows you to debug your application while it runs on an ST7 that has debug modules. STVD7’s in-circuit debugging features include advanced breakpoints, as well as trace recording for MCUs with a memory trace controller (MTC) module. For more information about in-circuit debugging with STVD7, refer to the STVD7 User Manual provided with your software package. Once you have finalized your application, STVP7 software provides a graphical interface for verifying memory sectors, checking the settings of the option bytes and programming the MCU. For more information about programming with STVP7, refer to the STVP7 online help provided with your software package. 24/39 ST7-EMU3 series emulator In-circuit communication configuration Figure 23.

To help you implement ICP and ICD in the development of your application, this section provides a summary of points you should consider when installing an ICC connector. Figure 24. In-circuit communication connector To connect to your application board for ICP and ICD, you need to install a 10-pin, HE-10 type connector (also called an ICC connector) and ensure the appropriate connections to your ST7. This connector receives the ICC cable and relays the signals required for ICP and ICD to your ST7. Using the ICC protocol requires that a minimum of 4 and as many as 6 pins of your ST7 be relayed to the ICC connector. These connection requirements are illustrated in Figure 25, below and summarized in Figure 4. 25/39 In-circuit communication configuration Figure 25. ICC interface ST7-EMU3 series emulator Table 3. ICC connection requirements Description ICC input/output serial data pin ICC output serial clock pin Device reset Programming voltage Main clock input for external Device power supply Device power supply (ground) Connects to ICC ICCDATA ICCCLK ICCRESET ICCSEL/VPP ICCOSC Not connected GND ST7 pin ICCDATA ICCCLK RESET ICCSEL/VPP OSC1 or OSCIN VDD VSS Isolation of ICCDATA and ICCCLK pins As soon as the emulator’s ICC Add-on is plugged into the application board the ICCDATA and ICCCLK pins must not be used by other application devices, even if an ICC session is not in progress. If the application uses these pins as inputs, isolation such as a serial resistor must be implemented to prevent other application devices from forcing a signal on either of these pins. The application board must not drive current in excess of 1mA. If the ICCDATA and ICCCLK pins are only used as outputs by the application, no signal isolation is necessary. For ST7 without an ICCSEL pin, during normal operation the ICCCLK pin must be pulled-up internally or externally (10KΩ pull-up required in noisy environments). This is to avoid entering ICC mode unintentionally during a reset. 26/39 ST7-EMU3 series emulator In-circuit communication configuration Isolation of the RESET pin During an ICC session, you must ensure that the emulator controls the ST7’s RESET pin so that no external reset is generated by the application. This can lead to a conflict if the application reset circuitry signal exceeds 5mA (push-pull output or pull-up resistor Microcontrollers to obtain a complete online selection guide, as well as documentation, software downloads and user discussion groups to help you answer questions and stay up to date with our latest product developments.
