XC17128ELPC20I

The XC17128ELPC20I is a high-density, non-volatile FPGA configuration device made by Xilinx. It combines non-volatile elements and programmable logic technologies to provide improved performance, password protection and advanced user configuration. The XC17128ELPC20I belongs to a type of memory known as Configuration Proms for FPGAs, designed to provide a simple, reliable way to store the configuration data for FPGAs.

XC17128ELPC20I is comprised of two separate components: a divider circuit to reduce the rate of input clock signals, and a non-volatile memory unit to store the configuration data. It uses standard single-ended bus lines to transmit data, as well as a few dedicated control signals. It uses a burst access protocol to transfer data to and from the device.

The standard features of the XC17128ELPC20I include the ability to configure multiple FPGAs simultaneously, and a built-in configuration lock to protect against unauthorized access. It also supports password protection and circuit-level ID codes. It is also capable of storing up to 17K 128-bit words of configuration data.

With regards to its application field, the XC17128ELPC20I can be used for storing configuration data for a variety of FPGA types, including Spartan and Virtex families. It can be used for board-level FPGA designs, for system applications such as cellular telephones, and for low-speed serial applications such as USB or serial ports. The XC17128ELPC20I is also suitable for use in a variety of embedded systems, such as medical and automotive applications.

The working principle of the XC17128ELPC20I is relatively straightforward. It initially reads in the configuration data from the FPGA, and then stores this data in its non-volatile memory unit. The FPGA is then reset, and the configuration data is then read back out of the XC17128ELPC20I and applied back to the FPGA.

In summary, the XC17128ELPC20I is a specialized memory element designed to store the configuration data for FPGA devices. It combines the non-volatile elements and the programmable logic technologies to provide improved performance, password protection and advanced user configuration. It supports multiple FPGA types and can be used in a wide range of system applications, such as cellular phones, embedded systems, and USB/serial ports.
