STMicroelectronics M48Z58Y-70PC1E1 Timekeeper RAM

The M48Z58Y-70PC1E1 is a high-performance, low-power non-volatile timekeeper RAM produced by STMicroelectronics. This 64 Kbit (8K x 8) NV SRAM integrates a quartz crystal and a lithium battery, which ensures that data is preserved and the real-time clock (RTC) continues to function in the absence of power. The device is particularly well-suited for applications requiring reliable data storage and precise timekeeping, even during power outages.

Featuring a 28-pin, 600-mil DIP CAPHAT™ package, the M48Z58Y-70PC1E1 is designed to be directly surface-mounted onto a motherboard, providing a compact and convenient solution for embedded systems. The encapsulated battery and crystal within the CAPHAT™ package ensure long-term reliability, making it an ideal choice for critical data and time-sensitive applications.

With a wide operating temperature range of 0°C to 70°C, this device is versatile enough for a variety of industrial and commercial environments. The access time of 70ns allows for rapid data retrieval, which is essential for real-time applications.

Key features of the M48Z58Y-70PC1E1 include:

• Integrated, ultra-low-power SRAM, real-time clock, crystal, and battery
• Byte-wide RAM-like interface, which simplifies integration into existing architectures
• Automatic power-fail chip deselect and write protection
• Programmable alarm output active in battery-backup mode
• Software-controlled clock calibration for high accuracy

The M48Z58Y-70PC1E1 is a perfect solution for systems that cannot afford to lose data or time tracking, such as point-of-sale terminals, industrial controllers, and security systems. Its integration of memory, real-time clock, and power-backup features into a single package reduces the complexity of system design and ensures continued functionality through power disruptions.

STMicroelectronics' commitment to quality and reliability is evident in the M48Z58Y-70PC1E1, providing a dependable non-volatile memory and timekeeping solution that engineers and designers can trust for their critical applications.
