Microchip Technology's AT17LV65-10NI FPGA Configuration EEPROM

The AT17LV65-10NI is a high-performance EEPROM (Electrically Erasable Programmable Read-Only Memory) device specially designed by Microchip Technology for the storage of FPGA (Field-Programmable Gate Array) configuration data. This product is an integral component for systems that require on-the-fly reconfiguration and offers a reliable non-volatile memory solution for FPGA applications.

Encased in a robust 20-lead PDIP (Plastic Dual In-line Package), the AT17LV65-10NI is engineered to interface directly with FPGA devices. Its compatibility with a wide range of FPGA families makes it a versatile choice for many electronic designs. The EEPROM operates over a voltage range of 3V to 3.6V, which aligns with common logic levels used in digital circuitry, ensuring easy integration into existing designs.

With a density of 65Kb, the AT17LV65-10NI provides ample space for storing configuration data, and the -10NI speed grade offers a 10 ns read access time, which facilitates rapid configuration loading, thus reducing system startup times. The device supports the industry-standard SPI (Serial Peripheral Interface), allowing for a simple, 4-pin serial interface with the FPGA for data transfer.

One of the key features of the AT17LV65-10NI is its user-friendly programmability. The device can be programmed in-situ with the FPGA itself, or with a standalone programmer, providing flexibility in how and when the configuration data is loaded. This feature is particularly useful for product updates and upgrades, as it allows for easy reprogramming without the need for additional hardware.

For added reliability, the AT17LV65-10NI includes a write protection mechanism, ensuring that the stored data cannot be inadvertently altered. This is critical for maintaining the integrity of the FPGA configuration and preventing system malfunctions due to corrupt data.

In summary, the AT17LV65-10NI from Microchip Technology is an essential component for FPGA-based systems, offering a compact, reliable, and easy-to-use solution for storing and loading configuration data. Its speed, capacity, and compatibility make it a top choice for designers looking to enhance the performance and flexibility of their FPGA applications.
