AT17LV512-10SC

While most microcontrollers and central processing units can be programmed directly, field-programmable gate arrays (FPGAs) rely on configuration proms to carry out the programming instructions that tell the device which sequence of logic functions it should execute. When choosing a configuration prom, it is important to select one that is compatible with the specific FPGA device or family of devices that you are working with. One such device is AT17LV512-10SC, which is designed to be used with FPGAs that are part of the Xilinx Spartan 3 family.

AT17LV512-10SC is a 32 pin configuration prom for FPGAs. It contains 512 Kbits of memory and includes an external oscillator with a maximum frequency of 20MHz. The device also contains a write protect pin, which allows the user to protect the stored data from accidental alteration. The memory can be divided into 8, 16, 32 or 64 Kbyte banks and can also be configured for up to four memory maps. AT17LV512-10SC supports a word/byte write mode with a maximum write cycle of 10 µs.

AT17LV512-10SC is an ideal choice for applications requiring high speed data transfer, such as multimedia processing, imaging, networking and industrial applications. It is also well suited for applications in which the configuration prom needs to be modified in real time, such as in-circuit testing or automated test-bench control. Furthermore, because of its flexibility and wide range of features, AT17LV512-10SC can be used to improve the performance of existing designs or to develop new ones.

The working principle for AT17LV512-10SC is simple. When the device is powered up, it reads all the data stored on the configuration prom and then configures the FPGA accordingly. Once the data is read, the configuration prom stores it in memory and the FPGA\'s internal logic executes the instructions on the configuration prom. When the FPGA is configured, the device will return a status byte and the user can then confirm that the device is working as expected.

In addition to providing quick and easy storage for data and configuration commands, AT17LV512-10SC also offers several operational features to enhance the usability of the device. It can support multiple start conditions, which allows the FPGA to be configured in scenarios where the configuration prom is disconnected or in reset state. Furthermore, the device supports a self-refresh mode, which means that the data stored in the configuration prom will not be lost during a power failure. This ensures that the stored data is still available when power is restored, even if the configuration prom has not been accessed in a long time.

In conclusion, AT17LV512-10SC is an excellent choice for FPGA designers and developers who want to ensure that their designs are flexible and can handle frequent changes. The device is well suited for applications that demand high performance and need to be reconfigured in real time. Moreover, the device offers several features that make it an ideal choice for situations where the configuration prom needs to be protected from accidental alteration. Combined with its low power consumption, AT17LV512-10SC provides a cost effective solution for FPGA applications.
