The M48Z128-120PM1 is a 128 Kbit x 8 Timekeeper SRAM integrated with a built-in 32.768 kHz oscillator and a real-time clock. This high-performance, low-power RAM is designed by STMicroelectronics to provide a reliable non-volatile memory solution with a built-in timekeeping functionality. It is particularly suitable for applications that require data and timekeeping to be maintained even when the main power is lost.

Key Features

• Integrated Battery: The device comes with a self-contained battery that ensures data retention and a functioning real-time clock for an extended period in the absence of an external power supply.
• Real-Time Clock (RTC): The RTC provides hour, minute, second, day, date, month, and year information with leap year compensation valid up to 2100.
• Memory Size: The SRAM has a memory capacity of 128 Kbits, organized as 16,384 words by 8 bits, providing ample space for data storage.
• Speed: Access times as fast as 120 ns, allowing for quick data retrieval and storage, which is critical for time-sensitive applications.
• Package: Enclosed in a 28-pin, 600 mil DIP CAPHAT™ package, the product is designed for easy integration into a variety of systems.
• Low Power Consumption: The device is optimized for low power consumption, making it ideal for battery-powered or power-sensitive applications.
• Automatic Power-Fail Chip Deselect and Write Protection: This feature writes protect the data in the event of a power failure, ensuring the integrity of the stored information.

Applications

The M48Z128-120PM1 is versatile and can be used in a wide array of applications, including:

• Industrial control systems
• Utility metering
