The XC17256ELVO8C is a Configuration Prom (IC) designed to help with the configuration of FPGAs. It is suitable for a range of applications in both the aerospace and defense industries, where the need for powerful, secure and reliable configurations is crucial. The XC17256ELVO8C has been specifically designed to provide a low cost, secure and reliable configuration solution for FPGAs. In this article, we will discuss its application field and working principle.

Application Fields for XC17256ELVO8C

The XC17256ELVO8C is a versatile Configuration Prom that can be used in a range of applications from aerospace to defense. Its secure and reliable design makes it suitable for a variety of environments, including those found in military, aerospace, and medical devices. It is also used in industrial applications, such as high speed communications systems, pulse code modulation (PCM), and digital signal processing (DSP).

Working Principle of the XC17256ELVO8C

The XC17256ELVO8C is designed with two main components: the programmable read-only memory (PROM) and the configuration controller. The PROM is made up of four banks of cells, each containing bits used to define the configuration. The configuration controller is responsible for reading and writing to the PROM. The configuration data is written to the cells in the PROM by the configuration controller. Once the data is written to a cell, the contents of that cell remain until the next write configuration pulse.

When the configuration process is initiated, the configuration controller reads the data from the PROM cells and adds a clock cycle for synchronization of the output. The configuration data is then stored in a buffer in the controller. This data is then passed to the external FPGA. The read/write operation of the XC17256ELVO8C is controlled through two pins - a read enable (REN) and a write enable (WEN). These pins are used to enable the read or write operations.

The XC17256ELVO8C is a secure and reliable configuration solution for FPGAs, adopting different methods to protect against malicious physical or logical attack. The programming is done in a secure manner, with no external or non-authorized access to the configuration bit-stream. The configuration controller also uses an authentication protocol to authenticate each bit-stream before programming the corresponding cell in the PROM.

Conclusion

The XC17256ELVO8C is a secure and reliable solution for use in FPGA configuration. It can be used in a range of applications, from aerospace to defense and industrial applications. The configuration controller is responsible for reading and writing to the PROM, and is controlled by two pins, a read enable and a write enable. Furthermore, the XC17256ELVO8C has the added security of authentication authentication protocol for a secure programming process.
