1 Description The configurator in-system programming cable (ISP cable) is a PC-only based cable that attaches to the parallel port of a computer. This cable can be used to download and verify configuration data cascading up to devices. This cable allows designers to quickly and economically program Atmel s family of AT configuration memories. It also provides support for new devices in the AT family prior to third-party programmer support being available. Therefore, it is a truly portable solution that allows engineers to work from their lab bench or office. Supported Devices The AT series configurators can interface with many SRAM-based families. This document is limited to example implementations for the following families: Atmel AT9K(FPSLIC), AT0K, ATK Xilinx XC000, XC00, Spartan, Spartan, Virtex, VirtexE Altera EPFK, EPFK, EPF0K Cypress Delta9K, 9K0, 9K0, 9K00, 9K, 9K00 Software Support Make sure to use the latest CPS software ( CPS is used to program configurators and supports both the ATDH00E programming board and this ISP cable. CPS also includes a conversion utility which supports Cypress, Xilinx and Altera file formats. The software, in conjunction with Atmel ISP cable, can be used to download an Atmel, Cypress, Xilinx or Altera programming file directly to Atmel s configurator(s). In-System Programming Cable ATDH Configuration EEPROM Memory CPS Configurator Programming System GUI Bbased Interface Supports Windows 9/9/000 and Windows NT Supports up to devices Supports programming reset polarity Verification routines to validate programming Accepts HEX, MCS, POF, RBF, HXU and BST file formats Online help Ability to enable or disable internal oscillator For specific information on using the CPS software, refer to the ATDH00E Programming Kit User Guide.

2 Connecting Cable to Target System The cable draws its power from the target system through and. Therefore, power to the cable, as well as to the target, must be stable. Do not connect any signals before connecting and. Connect the programming dongle to your printer parallel port. Connect the other end with 0-pin header to your target system (Figure ). Your target system should have the 0-pin header pin layout as follow in order to match the download cable (Figure ). The pin 9 of the 0-pin header on the target system is a key pin; therefore, it is cut off. The control signals generated by the software are fed to the header. The programming algorithms written by Atmel can be used to program an AT device in-system. Figure.

The 0-pin header is 0.' spacing () () (SW) () 0(/) Pin and Pin of the 0-pin header are the two signals which able to decode for cascading up to devices. The latest CPS software has the ability to control the signals SW, SW and by using the A pin of the device, you can select up to devices. Therefore, you could use a -to- decoder to cascade devices using our existing ISP circuit (see Figure ). Figure.

The ATC/LV00 device is implemented using two -Mb Configurator EEPROMs in a multi-chip module. The A pin of the first internal Mb is set to Low by the internal pulldown circuitry. An external. kω pull-up must be connected to the A pin of the second internal Mb in order to program the second device. To work with the ATC/LV00 devices, A should always have a pull up on the target system. The CPS software will implement the correct A value to program both internal devices. In fact, to program an ATC/LV00 is just like programming two -Mb Configurator EEPROMs in casacade configuration.

5 ATDH Due to the fact that the ATC/LV00 device is a single-die solution, an external pull-up or pull-down resistor can be connected to the A pin in order to program the data to the device. As long as the software A setting is matched with the hardware A pin setting, the data can be programmed to the device. The tables on page allow you to select any device out of the devices, which can work with the ISP download cable. The circuit is limited to example implementation for the Atmel vendor only. It is the same idea for Xilinx and Altera applications. In addition, user can still use the existing ISP circuit, which from the -megabit cascade document with the same ISP download cable.
