STMicroelectronics M48T248Y-70PM1 Timekeeper SRAM
The STMicroelectronics M48T248Y-70PM1 is a powerful and versatile Timekeeper SRAM that integrates a variety of features to ensure reliable and efficient operation for a wide range of applications. This integrated battery-backed SRAM and real-time clock (RTC) module is designed to provide a full-featured, byte-addressable 64 K x 8 non-volatile static RAM and a sophisticated RTC in a single package. The combination of volatile and non-volatile memory with an integrated timekeeping function makes this module particularly suitable for systems that require data and time to be maintained even in the event of a power loss.
Operating at a speed of 70ns, the M48T248Y-70PM1 provides quick access times to the SRAM, ensuring high-speed data retrieval and storage, which is critical for applications that demand fast and reliable memory operations. The module operates within a temperature range of 0°C to +70°C, making it suitable for commercial-grade applications.
The RTC part of the module includes many features such as a century flag, alarm interrupt, and programmable square wave output, which are essential for time-sensitive tasks and can be used in various applications such as data logging, process control, and time-stamping. The RTC is powered by an embedded lithium battery, which has a long shelf life, ensuring that the clock continues to run and the SRAM data is retained for an extended period even when the main power is unavailable.
The M48T248Y-70PM1 is housed in a 28-pin, 600 mil SOIC package, which is designed to be surface-mounted on a printed circuit board, saving space and reducing the overall footprint of the application it is used in. This package is also known for its robustness and reliability, making it a preferred choice for industrial and commercial applications.
This module is an excellent choice for designers looking for a non-volatile memory solution with an integrated real-time clock, offering ease of use, durability, and the trusted quality of STMicroelectronics products. Whether used in embedded systems, utility meters, or other time-critical devices, the M48T248Y-70PM1 ensures data integrity and precise timekeeping, even in the face of power interruptions.
