DS9122P Multi-Device Programmer for 1-Wire and I2C Devices
29Pages

General Description The DS9488-GP8 multidevice programmer for 1-Wire® and I2C devices simultaneously programs up to 8 devices that use the 1-Wire or I2C bus programming interface. A variety of socket adapters (DS9122 series) allows one programmer to support multiple IC types. Software drivers for every supported device are quickly and easily installed. LED status indicators immediately identify the pass/fail status of individual devices. Configuration settings allow access to device-specific features such as memory protection, read/write permissions, authentication, etc. These can be store as a configuration profile and automatically loaded in subsequent programming sessions. A USB interface connects the programmer to any computer. A convenient Windows® application allows for easy operation of the programmer.

DS9488-GP8/DS9122x Evaluation System Setup Required Equipment ●● Computer equipped with Windows and .NET Framework 4.5 or later ●● DS9488-GP8 EV kit board ●● USB A-to-micro-USB B cable ●● One to eight socket adapters for the intended ICs ●● One to eight ICs to be programmed Multidevice Programmer for 1-Wire and I2C Devices Selecting Socket Adapters One to eight socket adapters matching the IC packages must be purchased separately from Maxim before the programmer can be used. No socket adapters are included with the DS9488-GP8. A list of available sockets is provided on the DS9488-GP8...

Evaluation System Application Installation 1) Download the latest version of the DS9844-GP8 application software from http://content.maximin- Unzip the downloaded file into an empty directory. While observing safe ESD practices, carefully remove the EV kit board from its packaging. Inspect the board to ensure that no damage occurred during shipment. supplied USB A-to-Micro-USB B cable. All LEDs on more LEDs might remain on. The EV kit must be connected during application installation. Click on the setup application to begin installation. Follow the installation instructions. If prompted,...

Evaluation System If socket adapters have not been installed, remove power from the DS9488-GP8. Install the socket adapters, and reapply power. The programming procedure has three steps: • Device configuration • Production file creation Device Configuration 1) Navigate to the Device Configuration tab, shown in Select the device type to be programmed. Configure the device-specific options. Information about the options can be found in the IC data sheet and also in .pdf files under the Application Setup tab, View Device Help. If desired, click Save As... to record the configuration Device...

Evaluation System Production File Creation The production file compiles all the configuration informa- tion and data into a single .xml file to be used by the pro- grammer. After the device configuration has been input, press the Production File Create button and save the file to the folder defined in the Application Setup, File Outputs field. The programmer offers the option to encrypt the produc- tion file for secure transfer between sites. 1) Populate the desired sockets. 2) Navigate to the Programmer tab and select the active sockets as shown in Figure 4. An error is generated during...

Evaluation System Figure 5 shows the application following a programming session in which sockets 1-5 are populated, and socket 4 failed post-programming verification. Figure 6 shows the programmer hardware after the same programming session with the pass/fail LEDs illuminated. Production File Encryption The application provides the option to encrypt production files so they can be securely transferred between a mas- ter (configuration) system and one or more programming systems. The application generates an RSA public/private key pair that is used for the encryption and decryption. Figure...
