1. SERIAL NUMBERS For production programming it is often a requirement to have a unique serial number programmed into a designated location s on the selected device The PROGRAM process implements the serialization options selected here See 6 5 2 Select from None Sequential Hex LSB in low memory Random Hex Date Weekday Time in HEX YYYYMMDDWDHHMMSS Sequential BCD LSB in low memory Random BCD Date Weekday Time in BCD YYYYMMDDWDHHMMSS SN BUFFER ADDRESS Enter the required start address of the serial number SN DIRECTION Select LSB or MSB in Low memory For example A 4 byte serial number starting at 0000 being incremented by 1 starting at buffer address 00 Selecting LSB will mean that address 0 is incremented to FF with address 01 then being the overflow etc Selecting MSB will mean address 03 is incremented to FF with address 02 then being the overflow etc Page 28 SN STORAGE Select between NIBBLE BYTE and WORD SN Buffer Increment Default is 1 SN LENGTH Enter the number of bytes required for the serial number up to 8 bytes SN bytes 0 3 Least significant 4 bytes 8 digits SN bytes 4 7 Most Significant 4 bytes 8 digits AUTO DEVICE CHECKSUM Select OFF BEFORE SECURING or AFTER SECURING If turned ON after a d
2. This checks to see if a non blank device can be programmed with the data currently held in memory For example with an EPROM whose unprogrammed state is FF FO may be programmed to 00 but not to 0F In order to test whether a device is completely unprogrammed select ACTION BLANK CHECK This option checks if the device is blank all 1 s or all 0 s depending on the actual part Please Note It is possible for a device to appear blank even though it is not fully erased If problems are encountered in programming a device try erasing it for a longer period and then reprogramming Either the Blank Check or Bit Test can be performed when you select ACT ION AUTOPROGRAM This is selected from OTHER PROGRAMMING OPTIONS See section 6 5 1 6 5 Programming Devices IMPORTANT NOTE Data I O only use the specified programming algorithms as provided by the device manufacturers Whilst we make every effort to ensure that programming algorithms are correct the said algorithms are not guaranteed by the manufacturers and therefore cannot be guaranteed by Data I O Users are advised to ensure that devices work correctly in their systems before programming large quantities 6 5 1 Programming Options Prior to programming there are a number of different options available which can be selected using OTHER PROGRAMMING OPTIONS These are generally more applicable when using the programmer for larger quantity programming
3. Connect one end of the parallel cable to the programmer The other end of the cable should connect to the PC The cable will only fit the parallel port Tighten the holding screws thus ensuring that the cable will not cause programming problems NOTE The programmer does not have a power on switch It will power up when a signal is received from the computer and automatically power down when not in use STEP 2 Connect the power supply provided to the programmer and plug into any mains socket Alternatively fit 8 alkaline AA batteries USE ONLY THE POWER SUPPLY ADAPTER PROVIDED Replacements and adapters for different countries UK Euro Japan can be supplied by Data I O or their distributors STEP 3 Switch on the PC STEP 4 Run the SELF TEST program 3 3 Running the SELFTEST Program Your programmer has been supplied with self testing software which can check that the programmer has been installed correctly and can be used for fault diagnosis Before using the programmer for the first time whenever moving it to a new PC or if a fault is suspected run the SELFTEST program This has two purposes e It confirms which parallel port is being used by the programmer e It checks almost ALL of the programmer hardware WARNING ALWAYS ENSURE THAT THERE IS NO CHIP IN THE PROGRAMMER BEFORE RUNNING SELFTEST AS LEAVING A DEVICE IN THE SOCKET COULD DAMAGE THE CHIP AND GIVE FALSE RESULTS Page 10 To run the program c

8. As most programmers are still unable to provide 1 8 2 7V and 3 3V circuits manufacturers still allow the devices to be programmed at 5V The ChipWriter programmers can not only verify a low voltage device at its nominal operating voltage they can also program with voltages down as low as 1 8V as well giving much greater flexibility 6 2 Opening data files Files can be loaded from disk into the data buffer and saved to disk after editing using the LOAD and SAVE options in the FILE menu See section 6 2 8 for more details on saving files 6 2 1 Setting the data memory buffer size It is necessary to ensure that the data memory area has been set to a size large enough to accept the contents of the file to be loaded During the device selection process the buffer should be increased sufficiently to hold files of the size required for that part However there maybe occasions when the buffer requirement is even larger Do this using BUFFER BUFFER SIZE Enter the required size in KB The maximum buffer size available is determined by the available memory of the PC The programmer software uses approximately 150K plus the chosen buffer size The EMS software will use expanded memory for the buffer before using conventional DOS memory If the buffer cannot be increased sufficiently and gives a maximum size of typically 384KB then the EMM386 driver has not been correctly installed Check the CONFIG SYS file in the

30. ARY 8 4 CWCTEST Restrictions The CWCTEST software works by applying test vectors to the device to be tested If the chip passes the tests the device is assumed good otherwise it is assumed bad The search mode works by applying test vectors for all devices in the database and recording all devices that are good Herein lies the problem The chip is only tested at a frequency determined by the rate at which test vectors can Page 42 be applied to the device With the programmer hardware this is typically 500 3000 test vectors per second depending on PC Although this is much faster than most portable chip testers it is generally much slower than the target hardware The chip may pass the test vectors but may fail in the target system Similarly output loading may be completely different between system and tester Please Note If you suspect a chip is causing problems in your target system replace it The only test which is guaranteed is one with a negative result Testing of RAM s and LSI devices is slightly different This is done by the microprocessor inside the tester interfacing to the chip directly RAM tests are effectively performed on a 1MHz bus These results should therefore be more reliable However access times are not measured hence please note the above warning 9 5 CWCTEST Example The CWCTEST software allows simple logic gates to be tested quickly and easily As an example suppose a batch of 74LS245 devic
