AT17N256-10PC is an electrically erasable nonvolatile programmable read-only memory (EEPROM), a family of memory technologies used to store data in memory cells. It is a device used to store data and configuration information for programmable logic devices such as field-programmable gate arrays (FPGAs).

AT17N256-10PC employs a split-gate access transistor for each cell, also called a floating-gate transistor cell, that is similar to the memory cells most commonly used in dynamic RAM (DRAM). The “split gate” design has two transistors. The first one senses the charge on the floating gate, and the second one applies the programming or erasing signals to the floating gate. AT17N256-10PC is chosen for its extended endurance and superior availability. It is readily available in all operating temperature conditions, making it suitable for use in a wide range of FPGA application fields.

Configuration proms such as AT17N256-10PC are used in FPGAs to store the data and configuration that is required to make the FPGA work properly. In other words, they are used to set the FPGA\'s structure, mode of operation and data flow. They are generally programmed with an array of LUTs (Look Up Tables) or memory modules, depending on the FPGA application field. FPGAs can be used in various application fields, such as communications, automotive, aerospace, industrial, and medical.

The AT17N256-10PC features a non-volatile memory capacity of 32kbits. To write into or read from the chip, it requires three configuration pins such as Configuration Enable (CE), Configuration Data (CData) and Configuration Clock (CClk). It can be programmed through serial or parallel mode, either synchronous or asynchronous, depending on the application field. The data can be written in the read-only memory through four commands: Erase All, Program All, Read Status and Byte/Word Read.

Apart from the programming and erasing process, the AT17N256-10PC also has self-timed write protection, write inactivity and write protection monitoring. Additionally, the AT17N256-10PC accepts commands to improve performance and reliability such as mass erase, read status and byte/word read commands. This provides an efficient and reliable way to store configuration information that is required to make an FPGA work properly.

To sum up, AT17N256-10PC is an electrically erasable nonvolatile programmable read-only memory used to store data and configuration information for FPGAs. Its split gate design and extended endurance make it suitable for a wide range of FPGA applications. It is an ideal choice for configuration proms for FPGAs, providing an efficient and reliable way to store configuration information.
