STMicroelectronics M48T59Y-70MH1F Timekeeper SRAM

The M48T59Y-70MH1F is a highly integrated battery-backed SRAM with a built-in real-time clock (RTC) from STMicroelectronics, designed to offer a reliable and compact solution for timekeeping and data storage in a wide range of applications. This device is particularly well-suited for systems that require data and time to be maintained even when the main power is lost.

Key Features

• Integrated Power Supply: The device includes a factory-installed 3V lithium battery, which ensures that data and clock functionality are retained for over 10 years in the absence of an external power supply.
• Real-Time Clock: The RTC provides seconds, minutes, hours, day, date, month, and year information, with the accuracy and reliability required for critical time-keeping applications. It also includes automatic leap year correction up to the year 2100.
• Large Storage Capacity: With 64Kb (8K x 8) of non-volatile SRAM, the M48T59Y-70MH1F offers ample storage for data that must be preserved during power loss.
• Watchdog Timer: An integrated watchdog timer ensures system reliability and helps to prevent system failures by resetting the system if the main program fails to respond within a preset time frame.
• Programmable Alarm: The device features a programmable alarm function that can be set to a specific time, allowing for scheduled wake-up events or reminders.
• High-Speed Access: With an access time of 70ns, the SRAM allows for rapid data retrieval and storage, making it ideal for high-performance applications.
• Byte-Wide Interface: The straightforward byte-wide interface ensures easy integration into existing systems without the need for complex interfacing or protocol conversion.

Applications

Due to its robust feature set and reliable battery backup, the M48T59Y-70MH1F is an excellent choice for applications such as:

• Embedded systems and industrial controllers
• Utility meters and POS terminals
• Security systems and network equipment
• Medical devices and data loggers
