Product Description:
The E4809-045-167-C is a special board for storing BIOS settings in the case of CMOS SRAM technology. The 256-byte storage provides a memory to save critical system settings to be maintained even when the primary power is absent. The real-time clock (RTC) with its CMOS RAM has been integrated in this board, and the timekeeping features are also supported, which are crucial for system operation.
Its source of backup power is a lithium coin cell battery in order to avoid information loss at any time that the power is cut off. It is a non-rechargeable battery that automatically loses about up to three years of lifespan upon cutting off the main source of power for a long period. The board is equipped with a four-pin header for its connection, though pin two which is not usually accessible for external connection to a battery. This feature of the design offers older systems backward compatibility with a simple interface for integration. Something that used to be an obligatory stand-alone element now, with advancements in motherboard design, has succumbed to the integration of RTC and CMOS RAM as part of new chipsets, diminishing the need for discrete CMOS storage boards in new systems. But where dedicated BIOS storage and RTC functions remain essential in specialized uses, the E4809-045-167-C finds its place. Its energy-saving management is able to maintain system data in a very low energy cost state, providing systems reliability in which secure BIOS preservation is of utmost priority. Though it has a small form factor, the board is nevertheless an integral component of system reliability and clocking for legacy or industrial computing applications.
In the realm of data storage for extended periods and connectivity convenience, this model offers a safe method for storage of mandatory system settings aside from ensuring ease in integration to its corresponding hardware settings.
