XC17S05VO8C are non-volatile configuration proms designed to program high density FPGA devices. Furthermore, these Proms are designed to integrate seamlessly with standard programming algorithms such as JTAG. FPGAs offer various advantages to certain types of applications including the capability to reconfigure the logic through low power, high-speed communications links, allowing easy system upgrades. The configurations are stored on the XC17S05VO8C PROM and loaded into the FPGA during power-up. These Proms provide a cost-effective solution for programming and configuration of larger FPGAs.

Advantages and Applications

XC17S05VO8C PROMs provide the advantages of small form factor, high-speed operations and different densities options. These Proms are particularly well suited for low to medium density applications such as automotive, networking and telecommunications, storage, broadcast and consumer electronics. Because these Proms are non-volatile, their contents keep stored even when no power is supplied to the devices. This is an important feature for communication systems, as it ensures that all data is recovered after a power loss.

Working Principle

XC17S05VO8C PROMs use a specific technology to access and store configuration data. The data is organised in columns and rows depending on the size of the device. Each cell in the PROM stores a byte (eight-bit) of information. The on-chip memory efficiently matches the bit-length of modern FPGAs and can be reprogrammed with the same FPGA well into the future. By exploiting this non-volatile memory feature, the PROMs provide a cost-effective means for upgrading to higher FPGA densities. When the number of I/O pins in a FPGA increases with each generation, the PROMs have no need to be upgraded for each new FPGA generation.

Accessing the information on the PROM is accomplished using a instructions register. The instructions when executed enable the device to access and read the data on the PROM. The addressing of each bit of data is performed using standard commands such as READ and WRITE. These instructions enable the FPGA to access the data and get the desired results. The data can then be used to configure the FPGA. The same commands are used to reprogram the PROM with new data or erase the existing data.

Conclusion

In conclusion, XC17S05VO8C configuration proms are high-performance, non-volatile memory devices specifically designed for FPGAs. These Proms are cost-effective solutions for programming and configuration of larger FPGAs and also provide the advantages of small form factor, high-speed operations, low power consumption and different densities options. The on-chip memory is able to efficiently match the bit-length of modern FPGAs, making them suitable for a wide range of applications. The PROMs offer great flexibility, allowing them to be reprogrammed easily with the same FPGA, providing an upgrade option for future bigger FPGAs.
