Introduction The in-system serial programming (ISSP) programmer programs PSoC® ICs with hex files created with Cypress’s PSoC Designer™ software. 1.1 Functionality The programmer programs a PSoC chip mounted on your PCB, one at a time. It connects to your PCB with a 5-wire cable and to your PC with a USB cable. PDIP devices can be programmed using the ZIF socket provided on the CY3207-ISSP programmer. To automate programming operation, incorporate the programmer into a PC-based test system. The tester software communicates with the programmer-control software through a command line interface. The ISSP programmer can also be operated manually using the supplied Windows GUI software. The ISSP functions are as follows: ■ Program – Programs a hex file into a PSoC device. ■ Verify – Verifies that data in the PSoC device's flash memory matches data in the selected hex file. ■ Read – Displays data from a PSoC device's flash memory. ■ Flexible Connections to Target PSoC Device – Devices can be inserted directly into ISSP, connected via a test fixture, or programmed in-system on a product circuit board. For more information on ISSP, see application notes AN2014 Design for In-System Serial Programming (ISSP) and AN2026a In-System Serial Programming (ISSP) Protocol. 1.2 Kit Contents ■ ISSP programmer ■ ISSP software CD-ROM ■ 6-foot USB A to B cable ■ 2-foot programming cable ■ 9-Volt power supply ISSP Guide, Doc. # 001-15301 Rev. *E 5 Introduction 1.3 ISSP Hardware Down the center of the programmer (Figure 1-1) is a graphic showing the orientation of the various DIP packages; pin 1 down and the package justified to the top of the socket.

Using the ISSP Programming PSoC ICs with ISSP is versatile using the available options. 3.1 Socket Programming All packages are supported by the socket programming method. Surface-mount parts require an adapter. Insert the part to be programmed into the socket on the ISSP programmer. The ISSP supplies power. Execute the following: 1. Select Socket in the Programming Location drop-down box. 2. Select the appropriate part number in the Device Selection drop-down box. 3. Load a hex file. 4. Place a part in the socket and click one of the function buttons; Program, Verify, or Read. CAUTION: Disconnect the programming cable before socket programming; otherwise, programming the device in the socket may fail. 3.2 In-System Programming The device to be programmed is installed on a circuit board or held in an external fixture. Vdd power is supplied by the circuit board or external fixture. 3.2.1 ISSP Cable Connections to target systems are as follows: ■ Vdd (Vdd sense line) ■ GND (Ground) ■ XRES (external reset) ■ SCLK (serial clock) ■ SDAT (serial data) ISSP Guide, Doc. # 001-15301 Rev. *E 15 Using the ISSP Figure 3-1.

Burnaby, BC, Canada: http://www.mode-elec.com/. 3.2.2 Methods There are two ISSP methods. To control programming, one uses the XRES signal and the other uses the Vdd power-on ramp. 3.2.2.1 In-System – Vdd Stable On This method is recommended to control the target part. The programmer cycles the XRES high and begins programming. This method does not work on 8-pin parts because they lack the XRES pin. 3.2.2.2 In-System – Vdd Rising Edge This method works for all packages. The ISSP takes control of the target part when the Vdd is turned on. Each function sequence requires a rising edge on the Vdd. The rising edge triggers the start of the function. When the ISSP is commanded to perform a function, it waits until it senses a rising edge on Vdd. The sequence and delay between command and power application are important. The graphical interface prompts you to apply power when needed and turn it off when complete. The delay for ISSP software 1.89 and higher is 4.3 seconds. 3.2.2.3 In-System – Socket In-system programming with current is supplied by the ISSP. This method works for all packages. The ISSP takes control of the target part when programming is initiated and supplies current to the device and the target board. In low current mode, the ISSP supplies 5.0 V at about 30 mA. In high current mode, the ISSP supplies 5.0 V at about 150 mA. 16 ISSP Guide, Doc. # 001-15301 Rev. *E Using the ISSP The programmer supplies power and cycles XRES high, and then begins programming. This method does not work on devices with an XRES pin. See the product datasheet to verify that the device does not have an XRES pin. Current selection is accessed through Action Change Current. Select 30 mA or 150 mA current. CAUTION: Measure the current requirement of the target board before programming. If the current exceeds 150 mA, an external power source is required and ISSP modes Vcc Stable On or Vcc Rising Edge are used. CAUTION: High currents can damage the ISSP, the device, or both when programming. ISSP units that are damaged from use in high current mode are not eligible for replacement. Make sure the 9-V DC power supply is connected and operational before continuing. Failure to use the 9-V DC power supply can damage the host computer. 3.2.3 Access The software .exe file runs as a GUI if launched from Windows. If the software is started from a command-line window or directly from another program, it operates in command-line mode. 3.3 Standalone Programming ISSP software can be used to program supported devices independent (disconnected) of a PC. Set up the ISSP for Socket or In-Systems Programming mode, as described in Socket Programming on page 15 and In-System Programming on page 15. Independent read and verify functions are not available in the standalone mode. However, the program function in the standalone mode includes verification. When all parameters are set, programming mode is set, the device is selected, and the hex file is loaded, disconnect the ISSP from the PC. All the settings are saved into the internal flash memory of the ISSP. Power the ISSP by the 9-V power supply. A device can then be placed into the socket, or the ISSP can be connected via the programming cable to a PCB or fixture. For socket programming, place a device in the socket and press the white button on top of the ISSP. The green LED signals a passing programming sequence and the red LED signals a failed programming sequence. ISSP Guide, Doc. # 001-15301 Rev. *E 17 Using the ISSP 3.4 DOS Command Line Controls A DOS batch file called issp.bat included on the CD-ROM is a multifunctional file that can be used to view the return code from an ISSP call (among other things). Commands can also be typed directly on the command line. The following is an ISSP command, followed by a description of each field: issp [cy8cxxxxx] [example.hex] [-p|-v] [-s|-n] ■ ISSP is the call to the PSoC programmer executable. Precede it with a file path if issp.exe is not in the current directory. ■ cy8cxxxxx is the device part number you wish to program (upper or lower case). ■ example.hex is the hex file to program into the part or to verify the programmed part against. Note Ensure that the hex file is available in the directory where issp.exe is located; or add the location of the hex file in the command. Function options: ■ -p invokes the Program function (one function equals Erase, Program, Verify, and Protect). ■ -v invokes the Verify function. Location options: ■ -s invokes Socket Programming. ■ -n invokes In-System Vdd Stable On Programming. Specific command examples: issp cy8c26443 example.hex -p -s Programs example.hex into the device in the socket. issp cy8c26443 example.hex -v -s issp cy8c26443 example.hex -p -n Programs example.hex into the device in the system connected by the programming cable. The Vdd is stable during the whole programming sequence. These DOS commands return ‘0’ if the function is successful and a negative number if the function fails. 18 ISSP Guide, Doc. # 001-15301 Rev. *E Using the ISSP 3.5 Tester I/O Connector This connector is used to control the ISSP with logic level signals. The hex file and programming settings are loaded while the USB is connected to the PC. After the USB is disconnected, the ISSP can be powered by the 9-V supply and controlled through the Tester I/O connector. See Figure 3-2 for a description of the pins in the Tester I/O connector. The mating connector for connecting to the ISSP Tester I/O is manufactured by Phoenix Contact. The part number is 1881406 FK-MC 0.5/10-ST-2.5 and is available from Digi-Key. Figure 3-2.

Connect Pin 10 to a DC level equal to the testers logic high-level output. Pin 10 controls a level shifter between the ISSP and the tester. Figure 3-3 shows the Tester I/O signals during a programming sequence. The tester drives the “Start in” signal. The ISSP drives the Pass, Fail, and Busy lines. Figure 3-3. Tester I/O Signals Start In Start Out Pass Fail Busy 3.7 Test Counters A new feature in ISSP 1.80 and later versions is the ability to automatically keep track of the parts that are programmed. This feature is only available while the ISSP is connected to the PC via the USB interface. The total number of parts programmed and the number of parts that passed or failed is displayed in the window. Figure 3-4. Text Counters Window 20 ISSP Guide, Doc. # 001-15301 Rev. *E Using the ISSP For additional information, click the Summary button to bring up the following dialog. Figure 3-5. Summary Dialog Box This displays the time that the first and last parts were programmed, the part number, hex file, checksum, and pass/fail counts with percentages. Note that if more than one part number is programmed or if more than one hex file is used, the number of passed and failed parts for each configuration is recorded, but not displayed in this dialog box. To obtain this detailed data, print the report or save it to a log file. Any information entered in the Operator, Lot#, or Comment field is included in the printout and the log file. To reset the counters, click the Save and Reset Counters button from the Summary dialog. The counters are not reset until the data is saved successfully. To save an intermediate copy of the data without resetting the counters, select Save and Continue. Clicking OK saves what is entered in the Operator, Lot#, and Comment fields.
