XC17S40PD8I Application Field and Working Principle

Xilinx XC17S40PD8I is a one-time programmable PROM for FPGAs. Xilinx customers can integrate the Xilinx XC17S40PD8I PROM into their systems quickly and easily, as it is easy to program and requires no external power supply. Given its low-power requirements, low cost, and user-friendliness, the PROM can be utilized in a variety of applications.

Application Field

The Xilinx XC17S40PD8I can be used to store a variety of data that is essential for the system. It can store up to 64 kilobits of FPGA configuration data, along with other information such as Ethernet MAC address and serial number data. It can also be used for authentication and key store for secure communication.

The XC17S40PD8I PROM can be used in a range of consumer and industrial applications, including robotics, IoT devices, wearables, and e-signature applications. It is also suitable for automotive applications.

Due to its low power requirements, the PROM is suitable for use in field applications, especially in those with limited power resources such as battery-driven systems.

Working Principle

The Xilinx XC17S40PD8I uses a simple cell structure and EEPROM memory cell to store the configuration data. The stored data is maintained even when power is not available.

The PROM uses a serial communications protocol to receive configuration data that is then written to non-volatile memory. Once the configuration data is written, the user can control the FPGA configuration process and the devices can be programmed with the system configuration the XC17S40PD8I holds.

Data can also be updated without impacting the user design and system operation. The PROM can be erased with a special command and/or overwritten with fresh data.

Conclusion

The Xilinx XC17S40PD8I PROM is an ideal solution for storing data in FPGAs. It is easy to use, cost-effective, and can be used for a wide range of applications. The PROM’s low-power requirements make it suitable for use in field applications as well.
