STMicroelectronics M48T58Y-70MH1 Real Time Clock 64K 70ns Circuit

Description

Product Overview

The STMicroelectronics M48T58Y-70MH1 is a high‑precision real‑time clock (RTC) integrated circuit designed for demanding industrial and scientific applications. It features a 64‑kilobyte static RAM organized as an 8K×8 matrix, providing ample storage for time‑keeping registers, alarm settings, and user data. With a rapid 70 nanosecond access time, the device ensures swift read/write operations, minimizing latency in time‑critical processes.

Built on a robust silicon substrate, the M48T58Y‑70MH1 delivers exceptional temperature stability across a wide operating range, making it suitable for harsh environments. The package weighs only 0.01 ounces, allowing designers to integrate the component into space‑constrained boards without compromising performance. Its low power consumption further enhances suitability for battery‑operated or energy‑efficient systems.

Usage

Engineers and system integrators can deploy the M48T58Y‑70MH1 in a variety of settings where accurate timekeeping is essential. Typical applications include industrial controllers that coordinate machinery cycles, data acquisition systems that timestamp sensor readings, and embedded platforms that require reliable alarm functions. The clock’s stability makes it a trusted component for laboratory equipment, telecommunications infrastructure, and automotive control units.

Because the device supports a 64 KB RAM space, developers can store custom calibration data, configuration tables, or user‑defined time zones directly within the chip, reducing the need for external memory. Its fast access time enables real‑time monitoring and rapid response to events, which is critical in safety‑related applications such as emergency shutdown systems or precision motion control.
