Product Description:

This specific design E4809-045-201-A is a very adaptable Memory Board that originates from Okuma . The E4809-045-201-A memory broad operates as a printed circuit designed to expand capabilities in performance-driven systems. Its total weight reaches 0.61 kg which is a very small mass to handle and contains a battery cassette that is designed for sustained operation when used for real-time clock and non-volatile memory functions. High-speed storage emerges from the TCM501 static RAM chips which function as HM628120 components each containing 1M x 8-bit static RAM capabilities. The storage modules use custom controllers to connect with system CPUs through ICs that aid the process.

The RTC64613A real-time clock chip combined with a quartz crystal oscillator provides efficient timekeeping functions to generate the required clock signal. The functionality of interfacing equipment relies on ICs along with BCE and BCF components which control signal orientation while assuring high-quality and accurate transmission. It can generally function between 0 to 45 degrees centigrade for surrounding temperature. The E4809-045-201-A circuit broad has a combination of electrolytic inductive devices and capacitors that manage electricity regulation by minimizing noise or variations for desired voltage delivery. The board is interfaced with the larger system through an edge connector and multiple pin headers which assist in providing connections to outsider systems. The presence of these high-class components suggests that the board is designed with precision for industrial or embedded systems where stable memory performance and real-time processing are critical. It is a vital piece of equipment for systems requiring enhanced extreme capacity and reliability.
