The AT17C65-10JC is an 8K bit, serial Electrically Erasable PROM (EEPROM) that is developed specifically with FPGA configuration in mind. With the advancement of the FPGA technology, the need to reprogram the configuration in a convenient and reliable manner was essential. The AT17C65-10JC fulfills this need by offering nonvolatile configurable memory that can be written to and erased using electrical signals.

The AT17C65-10JC is a cost-effective solution as it operates with a single 3.3V supply and uses 64 bytes of data for storing 8 bits of data for coding for each of the 8K bits. It is available in an 8-lead 150mil DIP, 8-lead 0.6" SON package, and a 20-lead PW package. With its low power consumption of 4mA, the AT17C65-10JC becomes the ideal choice for many applications.

The AT17C65-10JC plays an important role in the field of FPGA configuration. It supports both synchronous and asynchronous initialization methods, thus allowing the user to select the most appropriate scheme for the application being implemented. Its programming time also provides an advantage over traditional nonvolatile memory devices, as it is able to write 1K bytes (8K bits) of data in around 50ms, allowing for quicker configuration of the FPGA.

The AT17C65-10JC also provides security features, such as Data Guard and Lock Bits, to protect the stored data. Furthermore, the device is also equipped with an on-chip voltage regulator, allowing for a single 3.3V power supply. As a result, the AT17C65-10JC can be used in a variety of applications, from consumer and industrial products to medical and automotive applications.

The working principle of the AT17C65-10JC is based on the nonvolatile memory technology known as FlashEEPROM. The device contains a built-in EEPROM array, and can be programmed and read using electrical signals. The device employs a serial data bus along with read and write control signals to interact with the external processor. This allows the FPGA to be configured in a very efficient manner.

The AT17C65-10JC supports both synchronous and asynchronous operation, making it the ideal choice for various FPGA configuration tasks. In synchronous mode, the device is controlled via a start and return nodes from the microprocessor, allowing the FPGA to be configured with minimal overhead. On the other hand, in asynchronous mode, the processor controls the EEPROM directly, allowing for faster configuration of the FPGA, as well as providing flexibility for applications that require a higher level of control or faster program/erase speeds.

In conclusion, the AT17C65-10JC is an exceptionally versatile device which can be used for a wide variety of memory applications, including FPGA configuration. Its nonvolatile EEPROM technology provides the user with an easy-to-access and reliable configurable memory, while its support for both synchronous and asynchronous operation allows for flexibility in a variety of applications. Its wide operating voltage range as well as its on-chip voltage regulator makes it suitable for a wide range of applications, while its ability to program 1K bytes of data in around 50ms makes it a great choice for implementing FPGA configurations.
