FPGAs and CPLDs are the most versatile digital devices used today. They provide flexibility to store and run data at high speeds and can be used in a variety of contexts. As such, reliable and secure memory is essential for accurate performance and operation of these devices. Configuration Proms (CFP) are an indispensable tool that enables the reliable and secure storage of configuration data on an FPGA. AT17LV256-10PC is a high-density CMOS configuration prom, designed for use with Altera FPGAs. This article aims to explain the application field and working principle of AT17LV256-10PC.

AT17LV256-10PC is a configuration prom specifically designed for Altera FPGAs. It is composed of a 256 Kb x 8 static RAM memory array, two 8-KB separate status registers, four 32-KB separate control registers and a synchronous four-wire serial bus for configuration data loading. It can be used with a variety of FPGAs, ranging from the cyclone family to the stratix series. The device is available in 32-pin PLCC and SOIC packages, providing a simple and cost-effective way to store FPGA configuration data.

AT17LV256-10PC is capable of storing multiple FPGA configuration images. When selected by the appropriate chip select and address inputs, the associated FPGA can be quickly and conveniently configured with the corresponding image stored in the device. The device also supports Multi- Boot and Byte-Select operations, enabling users to select or bypass specific devices or sections of memory within a larger memory array for optimal performance.

AT17LV256-10PC also supports optional write protect, programming lock and status register bits, giving it enhanced security features.
