The XC17256EPD8I is a configuration PROM specifically designed for use with FPGAs. It is a 256K-bit non-volatile memory device with a small footprint growing in popularity due to its exceptional read/write performance. As a configuration PROM, it is designed to store FPGA configurations during power up or while running, and can also be used for secure data storage and configuration holds.

The XC17256EPD8I has an 8-bit Instruction Registers for serial programming and several data registers (8/15/256/4096 bits). It also includes an integrity check in the form of an on-board CRC-16 calculation. The instruction registers are selected via a 4-bit synchronous instruction word, programmed into the 4-bit Instruction Control Register. Programming is done through a 3-wire serial interface using five instructions (WRITE, READ, ERASE, UNLOCK, and SET). The EEPROM is organized into sectors of 16K-bits divided into 16 pages of 1024 bits each. The READ operation reads out the data while the ERASE operation erases a block of any bits. Each page of 1024 bits is erased as one unit and the entire device can be erased at once.

The XC17256EPD8I is designed to store configuration data with lock-bits to protect the data from being altered. It provides a total of 64 lock bits to protect and limit access to certain areas of the memory device. It also supports extended temperature operation, offering the features of wide operating temperatures of -40 to +85°C. The XC17256EPD8I is a very useful PROM for FPGA designers since it has the ability to store and update a variety of data such as configurations, software, data sheets, differential outputs, and more.

The XC17256EPD8I offers exceptional read/write performance, fast programming, and high reliability. It has a faster write cycle than conventional ROMs, and can handle up to 1 Mbit/s of programming. The Device supports 8, 15, 256 and 4096 bit write cycles for efficient programming and also provides enhanced security features with lock-bits and power-on reset. The XC17256EPD8I can handle any range of data, up to 16 bits, written into any cell or page on the device Free of charge. Furthermore, it has a very small footprint, being a 28-pin, 8x8 mm package.

The main application fields for XC17256EPD8I are in embedded systems and nano computing. It can be used in the production of controllers, touch screen displays, and interfaces, as well as in robotics and automotive electronics. The XC17256EPD8I can also be used for a wide range of FPGA applications in aerospace, communications, digital medical, industrial automation and process control, and high-tech home entertainment products.

In conclusion, the XC17256EPD8I is a reliable, efficient and compact configuration PROM for FPGAs. It offers fast read/write performance, wide operating temperatures and extended temperature range options. It also supports a variety of programming methods, including 8, 15, 256 and 4096 bit write cycles. Furthermore, its lock-bits provide enhanced security features and its small package size allows for greater space savings on the board. Overall, with its exceptional performance and features, the XC17256EPD8I is an excellent choice for embedded system applications and FPGA configuration storage.
