The M48T201H870 is a high-performance, integrated timekeeper SRAM module from STMicroelectronics, a leader in the semiconductor industry. This product is designed to address the needs of applications requiring a combination of reliable non-volatile memory storage, real-time clock (RTC) functionality, and a battery backup system, all in a compact, easy-to-integrate package.

Key Features

• Integrated Power Supply: The module includes a factory-installed lithium battery, ensuring a long-lasting and stable power supply for the RTC and SRAM, maintaining data integrity during power outages or when the main power supply is turned off.
• Real-Time Clock: The built-in RTC keeps track of seconds, minutes, hours, days, date, month, and year, with leap year compensation up to the year 2100. It provides high accuracy and low power consumption, making it ideal for time-sensitive applications.
• Timekeeper SRAM: The module offers 2K x 8 bits of static RAM, which is directly accessible as a non-volatile memory. The data retention is ensured by the integrated battery, allowing the SRAM to retain data for over 10 years in the absence of power.
• Package: The M48T201H870 is offered in a 24-pin, 600 mil SOIC, providing a compact footprint suitable for space-constrained applications.
• Low Power Consumption: Designed for energy efficiency, the module operates with very low power consumption, making it suitable for battery-powered devices.
• Watchdog Timer: An additional feature includes a programmable watchdog timer that can be used to reset the system in case of a malfunction, enhancing system reliability.
