Microchip AT17LV002-10SU: A 2-Mbit Low-Voltage In-System Programmable Configuration PROM

In the realm of modern digital systems, particularly those built around high-performance FPGAs (Field-Programmable Gate Arrays), the need for reliable, non-volatile configuration storage is paramount. The Microchip AT17LV002-10SU stands out as a dedicated solution, engineered to streamline the configuration process and enhance system flexibility. This 2-Mbit Low-Voltage In-System Programmable Configuration PROM (Programmable Read-Only Memory) serves as a critical bridge between a system's programming interface and its target FPGA, ensuring robust and dependable operation.

The core function of this device is to store the configuration bitstream for an FPGA. Upon system power-up, the AT17LV002-10SU automatically transmits this data to the FPGA, enabling it to assume its designated function. This process is crucial for bringing the system to an operational state without external intervention. The in-system programmability (ISP) feature is a significant advantage, allowing the configuration data to be updated or modified after the device has been soldered onto the printed circuit board (PCB). This eliminates the need for physical removal of the component for reprogramming, thereby simplifying field upgrades, prototype iterations, and firmware deployments, which significantly reduces development time and cost.

A key specification of the AT17LV002-10SU is its low-voltage operation, supporting a 3.3V supply. This makes it ideally suited for today's low-power, portable, and battery-operated devices where power efficiency is a critical design constraint. Its compatibility with common FPGA families from vendors like Intel (formerly Altera) and Xilinx ensures its widespread applicability across various platforms. The "-10SU" suffix denotes a maximum access time of 10ns, enabling sufficiently fast configuration times for a broad range of applications, from industrial control systems to telecommunications infrastructure.

The device utilizes a serial access mechanism, which helps conserve valuable board space by minimizing the number of required interconnects. Its compact SOIC package is well-suited for space-constrained applications. Furthermore, it offers a high level of reliability with a typical endurance of 10,000 program/erase cycles, ensuring longevity over the product's lifecycle.

ICGOOFind Summary: The Microchip AT17LV002-10SU is an efficient and reliable low-voltage configuration PROM that simplifies FPGA-based system design. Its in-system programmability facilitates easy updates, while its fast access time and 3.3V operation make it a versatile choice for modern, power-sensitive electronic designs, ensuring a seamless and dependable configuration process.
