The XC17128ELVO8I is a Configuration Memory Prom from Xilinx that is used for programming the configuration of Field-Programmable Gate Arrays (FPGAs). The device has a memory range of 8 kilobits and comes in two voltage versions: two 5-volt versions and two 3.3-volt versions.

The XC17128ELVO8I is a non-volatile memory offering with bit-serial or byte-wide parallel configuration capabilities. The device can be used in a byte mode or a word-wide mode and offers simple programming capabilities, providing an efficient way to store data that controls the configuration of an FPGA. The use of an EEPROM-based configuration memory like the XC17128ELVO8I simplifies the design of an FPGA.

The main use of the XC17128ELVO8I memory is to ensure the reliable storage and configuration of an FPGA device. FPGA devices can be configured during programming, but a non-volatile memory like the XC17128ELVO8I allows for the device configuration to persist even when the device is shut down. This additional layer of programming capability helps to preserve the design integrity of an FPGA device.

The XC17128ELVO8I also has features that help with the protection of the device. Its functions include write-protection and corruption-avoidance, helping to ensure the security of the configuration data. The device also helps to reduce the clock-to-out rates of FPGA devices, allowing for improved performance.

The working principle of the XC17128ELVO8I design is to store the data required to configure an FPGA capacitively in its memory cells. The device stores the data as a series of logic states, providing the core information needed to configure the FPGA. When the XC17128ELVO8I device is initialized at startup, its stored data is used to configure the FPGA to the stored state.

The XC17128ELVO8I can also be used as a much welcomed caching device for FPGA devices, providing an additional layer of functionality as a caching tool for frequently required data. This feature allows for quicker retrieval of the required data, improving the performance of FPGA-based systems.

The XC17128ELVO8I device can also be used as an address multiplexer. By providing address information or data, the device is able to multiplex multiple address or data signals on a single port. This helps reduce the numbers of ports that need to be used on FPGA devices and simplifies device design.

In conclusion, the XC17128ELVO8I memory prom from Xilinx enables the secure, non-volatile storage of configuration data for FPGAs. It also offers features such as write-protection and error-avoidance to secure the data stored. Additionally, it can also provide caching capabilities and as an address multiplexer, helping to reduce the complexity of an FPGA device design. All these features makes it an attractive option for use in FPGA programming and design.
