DS9090K

S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices General Description The DS9090 evaluation kit (EV kit) provides the hardware and software necessary to evaluate and operate 1-WireM products in an easy-to-use PC environment. All 1-Wire EEPROM, EPROM, and ROM devices are readable with the DS9090 EV kit. All 1-Wire devices with memory or PIO/switches can be written with the DS9090 EV kit except 1-Wire EPROM devices*. In this way, the engineer can evaluate 1-Wire chips for potential design purposes or support end-product development activity. EV kit operation requires a host PC. Demonstration software consists of the OneWireViewer (a Java™ program). For 32-bit and 64-bit WindowsM operating systems, the OneWireViewer comes as part of the 1-Wire drivers install package. For other operating systems, refer to the online version of the OneWireViewer. *EPROM devices, such as the DS2502 and DS2506, require a different adapter (DS9097U-E25) to perform an EPROM write. This adapter can be purchased separately and requires a +12V power supply and a 25-pin to 9-pin serial port adapter (refer to the adapter’s data sheet for details). 1-Wire EPROM devices are available for sampling (up to a quantity of two).

TO92/PR35 Package Insertion Hardware Installation The DS9090 EV kit comes standard with a USB-to-1-Wire adapter (DS9490R). It is advisable to connect the USB end of the adapter to a free USB port after the installation of the software drivers is completed (see the Software Installation section). Connect the evaluation board to the PC with the supplied RJ11-to-RJ11 cable. One end of the cable should be plugged into the evaluation board and the other end into the DS9490R. Insert the 1-Wire chip of interest into one of the evaluation board sockets. See Figures 3 and 4 showing proper chip insertion/orientation. Keep in mind that if writing to DS250_ EPROM devices is desired, an alternate 1-Wire adapter (DS9097U-E25) is necessary. It is available for purchase separately from this kit. To program DS250_ EPROM devices with the DS9097U-E25, a +12V DC power adapter is required (available at most electronic supply stores). This is plugged into the power jack on the DS9097U-E25 adapter. Refer to the DS9097U-E25 data sheet for power-supply specifications, recommended power-supply models, and the polarity requirements of the 2.1mm power jack. Note that non-EPROM devices cannot be inserted in the evaluation board when programming EPROM devices. Caution: The +12V programming pulse that is seen on the 1-Wire bus during Maxim Integrated Figure 4. TSOC Package Insertion programming of EPROM devices damages non-EPROM devices. Remove any non-EPROM device from the evaluation board before attempting an EPROM write operation. This includes removing the J2 “Enable” jumper to isolate the DS28E04 from the +12V programming pulse. Enable Pins and Header Rows Enable pins and header rows are located on the board in various locations. Two locations are specified as enable pins and are jumperable. The first one (J5) enables the TSOC socket so that the 1-Wire chip residing in the socket can be communicated with through the 1-Wire bus. The second one (J2) is similar. J2 jumpers the DS28E04-100 evaluation circuit onto the 1-Wire bus. Figure 5 shows the J2 enable jumper in the DS28E04100 evaluation circuit. Header rows have also been placed on the DS9090 evaluation board, which allow other devices to be manually connected. Location J3 is one such header row. It is located just above the TSOC socket and provides electrical connections for the TSOC socket (pins 1–6). There is also an adjacent ground row for jumpering any TSOC pins to ground. Some ports such as the DS28EC20 (pin 3) or DS2413 (pins 1, 5) require additional pins to be grounded through a jumper when in a TSOC package. Location J4 provides five connections for the RJ11   3 S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices socket. Pin 1 provides +5V coming directly off the USB port through a current-limiting resistor. Pin 2 is the USB ground, pin 3 is the 1-Wire IO pin, pin 4 is the board ground, and pin 5 is the SUSO (“suspend”) pin for the DS9490R (displays when the DS9490R is in a “sleep” state). DS28E04-100 Evaluation Circuit A section of the evaluation board is dedicated to demonstrating the DS28E04-100 1-Wire chip. Before experimenting with the DS28E04-100, the circuit’s enable pins (J2) must be jumpered (see Figure 5). This jumpers the DS28E04-100 onto the 1-Wire bus, allowing the 1-Wire software to communicate with the device. Note the row of header pins at the bottom of the circuit, several of which can be jumpered. The pins labeled A0–A6 correspond to the seven address inputs that can be jumpered to modify a portion of the 1-Wire network address of the device. Other pins available are VCC, POL, and the PIO pins (P0 and P1). VCC can be jumpered in from the board when needed. The state of the POL pin determines how the PIO channels power up. For example, if the chip has to power up with all PIO channels off, the POL pin must be connected to a logic 1. The PIO pins (P0 and P1) are also brought out to the header pins. Software Installation Install the latest 1-Wire drivers package available at www.ibutton.com/software/tmex/. These drivers require a 32-bit or 64-bit Windows platform, specifically Windows XP (SP2), Vista, or Windows 2008 or 2003. Remove the DS9490R from the USB port before starting the installation. Only after the installation program is completed should the DS9490R be inserted. Once inserted, wait for the operating system to complete the plug-and-play process. For Windows 2003 and XP (SP2), the OS prompts about installing the DS9490R device with the Add Hardware wizard before continuing. Newer operating systems complete the plug-and-play process without the wizard. During the installation process, the drivers are set up to point to the USB adapter as the default port type and port 1 (USB1) as the default port number. The default port type and number settings can be changed at any time after installation by running the Default 1-Wire Net program that is installed with the drivers. To do so, simply click on Start → Programs → 1-Wire Drivers xXX (xXX stands for the OS architecture, either x86 or x64). Then click on the icon labeled Default 1-Wire Net. If problems are encountered during installation, refer to White Paper 6: 1-Wire Drivers Installation Guide for Windows, specifically the “Appendix A: 1-Wire USB Adapter (DS9490) Installation Help” section. Next, run the OneWireViewer Java demo. Click on Start → Programs → 1-Wire Drivers xXX. Then click on the OneWireViewer icon. This runs the OneWireViewer. If the OneWireViewer cannot find a suitable Java Runtime Environment (JRE), it prompts the user with a message to download the latest one from either www.java. com or sun.java.net. Once the OneWireViewer is running, the 64-bit ROM ID values (i.e., the 1-Wire network addresses) of all 1-Wire chips inserted into the evaluation board are displayed. Clicking on the chip’s address selects the chip and starts communicating with it. The OneWireViewer then makes other tabs available that contain functionality to exercise the chip (i.e., read and write data, files, exercise PIO pins, etc.). Figure 5. DS28E04-100 Evaluation Circuit 4   It is also possible to run the OneWireViewer on OS platforms other than Windows, but it could require special setup and/or additional software installation. Refer to the OneWireViewer website for more information at www.maximintegrated.com/onewireviewer. Maxim Integrated S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices Figure 6. OneWireViewer Screen Example DS9090 EV Kit Operation Select the 1-Wire device to evaluate and insert it into the appropriate socket, ensuring it is properly oriented. Jumper the appropriate enable pins for the TSOC socket (J5) and/or the DS28E04-100 evaluation circuit (J2). See the Hardware Installation section for help. Finally, connect the evaluation board to the PC. Run the OneWireViewer. If any difficulty is encountered, see the Troubleshooting Guide section. Another helpful resource is Application Note 3358: OneWireViewer User’s Guide. The OneWireViewer presents a Device List window located on the left-hand side of the main screen. It displays a list of the different 1-Wire devices found connected to the DS9490R. The 1-Wire device type inserted into the socket or header of the evaluation board should be shown in the Device List window, along with the 64-bit ROM ID lasered into the device. Figure 6 shows the DS28E04-100 in the Device List window, along with its 64-bit ROM ID value of 4A000000163A7A1C. From the Device List window select the part by clicking on it. Maxim Integrated Once the 1-Wire device has been selected, the righthand side of the main OneWireViewer screen is populated with different tabs. There are at least three tabs for each device contained in the DS9090 EV kit: Description, Memory, and File. A fourth tab labeled Switch is also available on those parts containing switches. Clicking on the Memory tab brings up the Memory Viewer as shown in Figure 6. The user has the choice of reading/writing any of the memory banks listed in the Banks section of the Memory Viewer. When done editing the raw page (entering in a hexadecimal number for each byte), click the Commit Changes button. Clicking Refresh rereads the contents of the 1-Wire memory. The File tab allows writing files to the device’s memory. To do this, the user needs to first Format the Device, then Create/Read/ Write/Delete files and directories. The Switch tab allows reading and toggling of the PIO pin states and clearing of activity latches. Refer to Application Note 3358 for further instructions on how to use the many features of the OneWireViewer.   5 S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices Evaluation Board Layout TOP LAYER (SIDE A, COMPONENT SIDE) BOTTOM LAYER (SIDE B) COMPOSITE GRAPHIC 6   Maxim Integrated S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices Evaluation Board Schematic VCC TP1 1WIRE 1 TSOC Enable 2 R1 100 GND TSOC 2 TSOC 3 TSOC 4 TSOC 5 TSOC 6 TP J5 RJ1 U1 USB VCC USB GND 1WIRE 1 2 3 4 TSOC 2 TSOC 3 SUSPEND 8 7 6 5 TSOC 6 TSOC 5 TSOC 4 1 2 3 1 2 3 4 5 6 J3 1 2 3 4 5 6 7 8 9 10 11 12 TSOC Breakout J1 TO92, PR32 SOCKET TP2 TSOC Socket 1-Wire TP GROUND VCC J4 1 2 3 4 5 VCC USB GND 1WIRE U2 VCCJUMP SUSPEND 1WIRE 16 VCC IO 2 1 RJ11 Breakout 7 6 11 J2 DS28E04 Enable 5 12 GND GND A0 A1 A2 A3 A4 A5 A6 P0 P1 POL 4 3 2 1 15 14 13 9 10 8 A0 A1 A2 A3 A4 A5 A6 P0 P1 POL JB1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 JUMPBLOCK 11 DS28E04 Software Development Resources Software Development Tools and Software Development Kits: www.maximintegrated.com/1-Wiresoftware Maxim Integrated Product Data Sheets and Application Notes: www.maxim integrated.com/1-Wire Online Support: www.maximintegrated.com/support   7 S9090 Evaluation Kit Evaluates: 1-Wire EEPROM, EPROM, and ROM Devices Troubleshooting Guide SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION The 1-Wire adapter’s device driver did not get installed properly Refer to White Paper 6: 1-Wire Drivers Installation Guide for Windows, specifically the “Appendix A: 1-Wire USB Adapter (DS9490) Installation Help” section.
