The M48Z58Y-70PC1 is a highly integrated battery-backed SRAM and real-time clock (RTC) module designed and manufactured by STMicroelectronics. This 5V, 64 Kbit (8K x 8) ZEROPOWER® SRAM offers a unique combination of volatile and non-volatile memory functionality, making it an excellent choice for a wide range of applications that require data storage and precise timekeeping, even in the event of a power failure.

At the heart of the M48Z58Y-70PC1 is a 64Kbit static RAM which is coupled with a fully integrated quartz crystal and lithium battery. This design ensures that data is retained and the clock continues to function for over 10 years in the absence of external power. The module operates at a speed of 70ns, providing fast access times for high-performance computing tasks.

The real-time clock is a highly accurate device that tracks time down to seconds, minutes, hours, days, weekdays, months, and years. It also has automatic leap year compensation up to the year 2100, ensuring long-term reliability without the need for manual adjustments. An additional feature of the RTC is the programmable alarm output that can be set to a specific time, allowing for scheduled wake-up events or system resets.

The M48Z58Y-70PC1 is housed in a 28-pin, 600 mil DIP CAPHAT™ package, which is designed for easy integration into a variety of systems. Its pin compatibility with JEDEC standard 28-pin DIPs allows for drop-in replacement in existing designs without the need for significant redesign.

This module is particularly suitable for applications in industrial control systems, utility meters, POS terminals, and other systems requiring data integrity and precise timekeeping. The ZEROPOWER® technology ensures that the energy consumed is minimal, making the M48Z58Y-70PC1 an environmentally friendly and cost-effective solution for maintaining data and time information.

In summary, the M48Z58Y-70PC1 from STMicroelectronics stands out as a robust, reliable, and energy-efficient memory and timekeeping solution, providing long-term data retention and precision for critical applications.
