Configuration Proms for FPGAs are widely used in electronic applications to reduce development costs. AT17LV65A-10JC is a very popular configuration prom for FPGAs and has a wide range of applications in various market segments. This article will discuss the application field and working principles of the AT17LV65A-10JC.

Application Field

The AT17LV65A-10JC is commonly used in automotive, medical, industrial and military applications. Its features and specifications make it suitable for these applications. It is used to store configuration information that is necessary to program and configure the FPGA. It provides the ability to store 168kbits of data which is enough to program the most advanced FPGAs available. The AT17LV65A-10JC can also be used to store general-purpose data, making it a versatile and reliable storage device. It is also very easy to program and configure, allowing engineers to quickly integrate it into their designs.

The AT17LV65A-10JC is also suitable for use in high temperature and radiation-hardened applications. Its ability to withstand up to 105°C temperatures and up to 20 KRad radiation makes it a reliable solution for mission-critical applications. It also has a wide operating voltage range of 1.8-5.5V, which makes it suitable for use in both 3.3V and 5V systems. Additionally, it is available in both through-hole and surface-mount packages, making it easily adaptable to different system designs.

Working Principle

The AT17LV65A-10JC configuration prom follows a three-wire Serial Peripheral Interface (SPI) protocol. It contains a static RAM array which is used to store the configuration data. The static RAM array is divided into 16 addressed memory blocks, each containing 8Kbits of data, and is controlled by a state machine. When a read or write command is sent from the SPI bus master, the state machine will access the RAM array accordingly. Once the data transfer is complete, the command is acknowledged by the state machine and the data is stored in the RAM array for future use.

The AT17LV65A-10JC also contains an on-chip register, which is used to control the operation of the device. The register contains information such as the block size, operating voltage, clock frequency, temperature range and other pertinent data required to run the device. The AT17LV65A-10JC can also be used to store general-purpose data, which can be read or written over the SPI protocol.

In addition to providing reliable storage of configuration data and general-purpose data, the AT17LV65A-10JC also offers an extra layer of security and reliability. The device is protected by an on-chip, one-time programmable nonvolatile memory, which ensures that the stored data is safe even if power is lost or removed. In addition, the device supports a variety of error checking and correction algorithms, making it even more reliable.

The AT17LV65A-10JC is a reliable and versatile configuration prom for FPGAs. Its wide range of applications, suitability for high temperature and radiation-hardened applications, and its state-of-the-art security features make it the ideal choice for applications in automotive, medical, industrial, and military fields.
