AT17LV256A-10JI is a configuration Prom used to program FPGAs. A FPGA (Field Programmable Gate Array) is an integrated circuit designed to be configured by the user after manufacturing. It provides the user with the flexibility to customize the function, logic and even the physical size and pin-outs of the integrated circuit. FPGAs are used in a wide range of applications such as image processing, data control, telecommunications, military/aerospace and more.

AT17LV256A-10JI is a 256 Kbits serial-response cryptographic configuration prom in a 20 pins chip carrier package. It comes with 4 configurable parameters, which include the speed grade, temperature range, security feature and timeout feature. It can be programmed using the company’s ISSP (In-System Self Programming) or Serial Configuration Interface (SCI) supporting a range of programming devices such as USB, parallel port or RS-232 (Serial). The programming process is fast and reliable, making it an ideal choice for FPGA applications.

The AT17LV256A-10JI is designed to store up to 32K words of user-selectable configuration data up to 256K bits. It provides two operating modes, masked mode and unlocked mode. In the masked mode, all CR protection bits are programmed and the configuration data is read-protected. In the unlocked mode, all CR protection bits are not programmed and the configuration data is writable by the user. Furthermore, it features advanced features such as non-volatility, low-cost, high write speed, high reliability and radiation tolerant. All these features make AT17LV256A-10JI an ideal choice for many FPGA applications.

AT17LV256A-10JI features a cryptographic controller and offers additional features that protect the FPGA design from piracy and counterfeiting. In addition to the encryption key, the cryptographic controller provides an antifuse link to protect the configuration data from external attacks. It also allows a limited number of reconfigurations during power cycling. Moreover, it has an integrated real-time checker which continuously monitors the integrity of the FPGA.

The AT17LV256A-10JI is designed to work with a variety of FPGAs including those manufactured by Xilinx and Altera. It supports a range of programming languages including Verilog, VHDL and System Verilog. The working principle of AT17LV256A-10JI is relatively simple. The configuration data is written to the AT17LV256A-10JI register and from there it is transferred to the FPGA. The FPGA is then programmed with the configuration data and configures itself accordingly. The same process is repeated each time the FPGA is powered-on or reset.

AT17LV256A-10JI is a cost-effective, effective and secure solution for FPGAs. It provides an added level of protection and reliability to FPGAs and also helps reduce counterfeiting and design piracy. The robust security features make it an ideal choice for many FPGA applications. Furthermore, the fast configuration process and easy user-programmability make it a perfect choice for today’s FPGA designs.
