Memory, specifically Configuration PROMs for FPGAs, is a type of memory device used for storing configuration information for various integrated circuits and enforcing usage rights, such as data access restrictions and license requirements, among others. AT17LV256-10SU is a non-volatile memory device specially designed for Field Programmable Gate Arrays (FPGAs) applications, compliant with the x16 Organization standard. In this article, we will discuss the application field and working principle of AT17LV256-10SU.

AT17LV256-10SU is a stand-alone, single-voltage, non-volatile FPGA Configuration PROM with x16 Organization. The non-volatile memory array consists of 128 Kbits 32,768 x 16-bit words. The AT17LV256-10SU device is configured serially, with a maximum clock frequency of 30MHz. The device offers these features designed for both logic design and power electronics applications: endurance, speed, and overall system protection from corruption resulting from power failures or accidental programming. The device has a maximum write-cycle of 10K cycles and an endurance range from 5K to 10K cycles.

The AT17LV256-10SU can be used for many applications, such as programmable logic controllers, system controllers and DSPs, FPGA configuration, automotive, industrial, and networking applications. For example, AT17LV256-10SU non-volatile memory devices are used in FPGA designs to store the desired configuration parameters. A FPGA is a logic-based semiconductor device which is programmed and reprogrammed with external circuitry using a digital bitstream. When a FPGA operates in its default mode, the programming is stored in the AT17LV256-10SU, thereby allowing the FPGA to configure itself according to the programming stored in the AT17LV256-10SU device.

The Atmel AT17LV256-10SU device has a built-in protection circuit to prevent accidental write operations from erasing its content. It also has a two-byte write-protection byte to prevent accidental write operations. Furthermore, the memory array is organized in 32,768 page of 16 words and each page is accessible with 8-bit addressing to obtain the desired page content for further processing. This memory organization allows the user to access any page of the device with minimal overhead. The device also has an internal system reset functionality which allows it to survive power-failure events. This internal system reset feature helps to ensure that the device is always in a known and predictable state.

AT17LV256-10SU operates with a single 3.3V Vcc supply and is available in a wide operating temperature range. It is packaged in a 48-pin SOIC (Small Outline Integrated Circuit) package. AT17LV256-10SU devices are popularly used for cost effective and reliable configuration of FPGAs due to its wide operating temperature range, small size, low power-consumption, robust fault-tolerance, and high storage capacity.

In conclusion, the AT17LV256-10SU is a single voltage non-volatile FPGA configuration PROM memory device, compliant with the x16 Organization standard. It is capable of storing up to 128Kbits of data, and its array is organized in 32,768 pages of 16 words which can be accessed through 8-bit addressing. The AT17LV256-10SU offers many advantages such as power-fail protection and low power consumption, making it ideal for a wide range of applications, such as programmable logic controllers, system controllers and DSPs, FPGA configuration, automotive, industrial, and networking applications.
