FPGAs, short for Field Programmable Gate Arrays, are integrated circuits designed to be programmed by the user to perform specific tasks. They are often used in embedded systems, where they provide flexibility and performance, while keeping development costs low. Configuration PROMs are used in FPGAs to store the configuration data and settings needed to initialise and program the chip. The AT17LV040-10TQI is a high density PROM designed for use with FPGAs.

The AT17LV040-10TQI is a 4K x 8 Configuration PROM with a 20 nm technology node. It features a 16 pin TQFP package, low power consumption and a wide range of operating temperatures from -40°C to +85°C. This makes it suitable for a variety of applications in harsh environments, including industrial and automotive.

The AT17LV040-10TQI features an automatic chip select signaling (ACSS) interface, which allows the FPGA to detect the PROM and read data. This eliminates the need to manually configure, reset and initialize the chip. The ACSS interface is designed to be easily implemented with minimal additional logic and no special control signals.

The AT17LV040-10TQI also provides a fast program and erase time of 50 μs, allowing it to be quickly programmed, tested and reprogrammed as needed. The programming algorithm used is enhanced with four thresholds and a two-page write capability, which helps to improve the ROM security.

The AT17LV040-10TQI is designed to be used with FPGA chips from different manufacturers and is compatible with most popular FPGA architectures. The device is rated for over 1,000 P/E cycles and provides an affordable solution for applications where cost and reliability are important factors.

Overall, the AT17LV040-10TQI is an excellent choice for use with FPGAs. It provides a high density, low cost PROM solution, with a wide temperature range and enhanced security features. The ACSS interface ensures fast and easy integration with popular FPGA architectures, and the fast programming algorithm makes it ideal for applications that require quick in-the-field reconfiguration.
