XC17256EVO8I is a type of configuration PROMs for Field Programmable Gate Arrays (FPGAs). It acts as a non-volatile memory device which enables the high-speed programming of FPGA even after the power shut down or data lost.

The XC17256EVO8I is built for a variety of applications such as industrial, automotive, communication, military, automotive and consumer markets. The device has advanced features such as dual Bank architecture for easy device configuration, automatic configuration on power-up as well as 2x16 MBit of system memory.

The XC17256EVO8I has a few advanced features which makes it an attractive choice for applications. For example, it supports a SPI-slave interface allowing the PROM to be controlled by a host processor while the FPGA is in production. It also provides extended reliability with error correction and detection support. Furthermore, the PROM can be configured with error correction, advanced data protection and other reliability based parameters to meet customer requirements.

In terms of working principles, the XC17256EVO8I utilizes an on-board flash memory to store configuration bits which are transferred to the FPGA in a two-step process. In the first step, the Configuration Item Register (CIR) acts as an addressable location stored on the PROM from where the first n-bits are retrieved and loaded into the FPGA\'s configuration cell for programming. In the second step, the Configuration Bulk Order (CBO) acts as a bit control register from where the next n-bits are retrieved for programming.

The XC17256EVO8I is also designed to ensure that the programming of the FPGA is reliable and requires minimal effort from the user. It features AutoConfig mode which makes it easy to program FPGA upon power-up. In addition, the PROM supports error correction and data protection to increase reliability.

In summary, the XC17256EVO8I is a type of PROMs for FPGAs which provides reliable device configuration in a variety of applications. Its on-board flash memory enables the two-step programming process, while the advanced features such as AutoConfig mode and error correction enhance the overall reliability of the configuration process.
