The M48T59Y-70PC1DS is a high-performance 64 Kbit Timekeeper® SRAM designed by STMicroelectronics. This integrated device combines a binary counter with a quartz crystal and a battery to maintain a full-function, real-time clock (RTC) alongside non-volatile static RAM. The unique integration of these components makes it an ideal solution for systems requiring reliable timekeeping and data storage that persists through power loss.

Key Features

• Integrated Power-Supply: The device includes a factory-installed lithium battery that provides a long-term, stable power source for the RTC and data retention in the absence of an external supply.
• Real-Time Clock: The M48T59Y-70PC1DS features a programmable alarm, interrupt functions, and a leap year compensation valid up to the year 2100, ensuring accurate timekeeping and scheduling capabilities.
• Memory Capacity: With 64 Kbits of SRAM, users have ample space for data storage that's protected against data loss during power failure scenarios.
• Speed: The access time of 70ns allows for rapid data retrieval and storage, ensuring efficient operation within a system.
• Package: The device is available in a 28-pin, 330 mil DIP package, making it suitable for through-hole PCB mounting and compatible with a wide range of applications.

Applications

The M48T59Y-70PC1DS is versatile and can be used in a variety of applications where reliable timekeeping and data retention are essential. These include:

• Telecommunication systems
• Embedded systems
• Industrial control systems
• Network servers
• Point of Sale (POS) terminals

Reliability and Durability

STMicroelectronics has designed the M48T59Y-70PC1DS with durability in mind. The integrated battery ensures a minimum of 10 years of data retention and clock functionality after the first power-up, providing peace of mind for long-term applications. Its robust construction and proven technology make it a reliable choice for critical systems where data integrity and accurate timekeeping are paramount.
