STMicroelectronics ST7-EPB Programming board UM0028 User manual Rev 4 June 2006 www.st.com BLANK UM0028 User manual ST7-EPB Programming board Introduction Thanks for choosing ST7! This manual will help you setup and start using your ST7-EPB programming board. ST7-EPB programming boards allow you to program ST7 microcontrollers that have EPROM, EEPROM and FLASH memories. Your programming board links, via parallel port, to a host PC running ST7 Visual Programmer (STVP7) software. This software interface allows you to customize and control the programming of an application to your ST7. The layout of your programming board varies depending on the type of EPB you have ordered, as each programming board is designed to program a different sub-family of ST7 MCUs. Some programming boards also support either In-Circuit Programming (ICP), or In Situ Programming (ISP) of your ST7 while it is mounted on your application board. Note: A complete listing of the ST7 family of programming tools, including the devices and programming modes that they support is provided in ST7 Visual Programmer (STVP7° Release Notes. Figure 1.

In addition, some programming boards also support connections for In-Circuit Programming (ICP) or In Situ Programming (ISP). To help you get started programming with your EPB, the following sections provide: ● ● ● ● ● 1.1 Section 1.1 – a checklist of components delivered with your ST7-EPB Section 1.2 – instructions for setting up your programming board Section 1.3 – instructions on the use of programming sockets Section 1.4 – instructions on setting up a connection for in-circuit programming Section 1.5 – additional notes about in situ programming Delivery Checklist The following items are delivered with your programming board (see Figure 2): 1. One ST7MDTxx-EPB programing board. 2. One power supply 3. One parallel cable Optional 4. One 10-pin, HE-10 type ribbon cable with programming boards that support ICP or ISP Figure 2. Parts delivered with ST7-EPBs (not to scale) 1 ST7-EPBs come in several types, which support the programming of different families of ST7 and package types. The sockets and connectors on your programming board will vary depending on the type of ST7-EPB you have ordered, and may not correspond exactly to the version shown here. 3 2 6/15 UM0028 Rev 4 ST7-EPB 1 Getting Started Figure 2. Parts delivered with ST7-EPBs (not to scale) Optional 4 1.2 Setting up your ST7-EPB To setup your ST7-EPB programming board: Note: 1. Shut down and power-off the host PC. 2. Connect one end of the supplied parallel cable to the EPB’s P1 connector and the other end to one of the host PC’s parallel ports (LPT1 or LPT2). Be sure to use the parallel cable provided with your kit — using a longer parallel cable may cause malfunctions. Connect the cable directly between the host PC and the programming board — inserting additional cables or switch boxes between the host PC and the programming 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 the programming board. However, if a malfunction of the board occurs, please remove the dongle and reconnect your EPB. 1. Connect the power supply to the programming board. Ensure that the power supply is adapted to the mains voltage and outlet type used in your country. Note: The board can be supplied from the integrated power supply provided with the board, or from an external +15 VDC / 0.5 A power supply. 2. Power on the host PC. 1.3 Using the programming sockets All ST7-EPBs come with one or more sockets for programming. The sockets that are available to you for programming will vary depending on the packages for the ST7 subfamily that your programming board supports. Regardless of the type of socket, when installing an ST7 for programming you must ensure that pin 1 of the ST7 corresponds with pin 1 of the socket. To install your ST7: 1. Caution: Set up the EPB as described in Section 1.2 on page 7. 2. Identify the socket for your device package on the programming board. 3. Open the socket, or lift the lever (for ZIF sockets) and place the device into the socket with pin 1 matching the pin 1 indicator on the programming board. Take care when placing the device into a socket so as not to damage the device or the board. Forcing the MCU into the socket may result in damage to the socket.

Use ST7 Visual Programmer to program your device. For more detailed information about its use, refer to the software’s online help. 1.4 Using an in-circuit programming connection Some ST7-EPB programmers allow in-circuit programming (ICP) of supported ST7 Flash microcontrollers, thanks to the In-Circuit Communication (ICC) protocol developed for ST7. This section provides information to help you setup your application HE-10 type connector board for in-circuit programming of your ST7. To take advantage of ICP you must have an ICC connector (10-pin HE-10 type) installed on your application board allowing you to connect it to your programming board with the provided ICC cable (10-pin ribbon cable). This connection is illustrated in Figure 4. Figure 4. 8/15 In-Circuit Communication interface UM0028 Rev 4 ST7-EPB Note: 1 Getting Started When using the ST7MDTS1-EPB, the VDD_APPLI is not connected to the ST7. When setting up your application for in-circuit programming, refer to the ICP Interface diagram in the In-CIrcuit Programming section of the ST7SCR Datasheet, instead of the diagram provided above. Using the ICC protocol for in-circuit programming requires that a minimum of 4 and as many as 6 pins of your ST7 be connected to your programming board (see Table 1). Additional notes about these connections are provided in this section. Table 1. ICC connection requirements ST7 pin Connects to... ICCDATA ICC input serial data pin ICCDATA ICCCLK ICC output serial clock pin ICCCLK RESET Device reset ICCRESET Programming voltage ICCSEL/VPP Main clock input for external ICCOSC VDD Device power supply VDD_APPLI VSS Device power supply (ground) GND ICCSEL/VPP OSC1 or OSCIN # # Optional connection for ST7MDTxx-EPB, see text. Note: For specific ICC connection requirements for microcontroller introduced after the publication of this document, please refer to the microcontroller datasheet. Isolation of ICCDATA and ICCCLK pins From the moment that your ST7-EPB is plugged into the application board, the ICCDATA and ICCCLK pins must not be used by other application devices, even when you are not programming the ST7. 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. Isolation of the RESET pin During an ICC session, your ST7-EPB must control the ST7’s RESET pin. No external reset can be 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
