The XC17S20PD8C configuration PROM solutions are designed to provide an easy and cost-effective solution for configuring Virtex™-E FPGAs. This PROM contains the Flex® 10K and the Virtex architecture. The XC17S20PD8C configuration PROM solution provides configuration circuitry, an EEPROM, the IC package and board layout elements to enable the user to benefit from features such as fast first-time programming and quick recovery in case of errors.

Application Field

XC17S20PD8C PROM solutions are used in applications such as flash-pointing a FPGA, designing and manufacturing new test systems, development and reprocessing of FPGAs, as well as reconfiguring FPGAs for experimentation purposes.

They are also used in more load-intensive applications such as for embedded controllers, high-performance processors, etc. where a robust and fast configuration process is needed. Moreover, XC17S20PD8C PROM solutions provide a reliable alternative to other configurable memories such as ROMs or EPROMs.

Working Principle

The XC17S20PD8C configuration PROM solutions offer multiple features to provide fast, reliable and secure configuration. These features include:

• Single-bit modify operation
• EEPROM with register and power isolation
• Dual clock modes – locked or free
• Write mode reset
• Ready/busy status
• Automatic recovery of an improperly programmed PROM

The XC17S20PD8C configuration PROM solutions operate by providing a write pulse to the PROM input, which is then incremented to the next location. The next location is then written with the new data. This is repeated until the desired configuration is satisfied. After the PROM is programmed, the configuration is verified by a read operation. Once verified, the device is ready for the next configuration.

The XC17S20PD8C configuration PROM solutions also allow the user to modify individual bits in the configuration, making it easier and faster to make changes during development and testing. This feature also allows the user to store data in the EEPROM prior to configuration, which can be used to store configuration information or any other data related to the application.

The XC17S20PD8C configuration PROM solutions also provide a secure write facility that ensures the integrity of the configuration by preventing the unintentional modification of stored data. The write protection is enabled during configuration, preventing changes to the PROM contents until the write protection is disabled.

The XC17S20PD8C configuration PROM solutions also offer a fast first-time programming and quick recovery in case of errors. The fast first-time programming reduces the cost of development and testing as it eliminates the need for additional programming cycles. The quick recovery in case of errors ensures the system is up and running as quickly as possible.

Overall, the XC17S20PD8C configuration PROM solutions offer a simple and cost-effective solution for configuring Virtex-E FPGAs. The features of the XC17S20PD8C configuration PROM solutions provide a reliable and secure solution for configuring and reprogramming FPGAs and offer fast first-time programming, quick recovery in case of errors and write protection.
