High-Performance In-System Programmable Configuration Memory: Microchip AT17LV010-10CU 1Mbit EEPROM

In the realm of modern digital systems, the demand for reliable, high-performance, and reconfigurable non-volatile memory is paramount. The Microchip AT17LV010-10CU stands out as a robust 1-megabit (128K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) specifically engineered for in-system programmability (ISP). This device is particularly critical for storing configuration data for complex programmable logic devices (CPLDs) and field-programmable gate arrays (FPGAs), where it ensures seamless and rapid device reconfiguration without physical hardware intervention.

A key feature of the AT17LV010-10CU is its high-speed access time of 10ns, denoted by the "-10" in its part number. This exceptional speed is crucial for contemporary applications, as it minimizes wait states and allows the host processor or controller to read configuration data rapidly, thereby reducing overall system boot time and enhancing performance. The device operates on a low 2.7V to 3.6V single power supply, making it ideal for power-sensitive and portable applications.

The in-system programmability capability is arguably its most significant advantage. Engineers can reprogram the memory contents while the device is soldered onto the printed circuit board (PCB). This eliminates the need for physical removal, streamlining field upgrades, firmware updates, and design iterations, which significantly reduces development time and cost. The EEPROM technology guarantees high reliability and data retention, with an endurance rating of typically 10,000 write cycles per sector and data retention of over 200 years.

The AT17LV010-10CU utilizes a simple and standard parallel interface for easy integration into existing system architectures. It is offered in a compact 8-lead PLCC package, suitable for space-constrained designs. Its ability to function reliably across the industrial temperature range further underscores its versatility for a wide array of demanding environments, from consumer electronics to industrial automation and telecommunications infrastructure.

ICGOODFIND: The Microchip AT17LV010-10CU is a superior solution for configuration storage, offering an optimal blend of high-speed operation, in-system reprogrammability, and proven reliability. It is an indispensable component for designers seeking to build adaptable and future-proof electronic systems.
