STMicroelectronics M48T37V-10MH1F Timekeeper SRAM

The M48T37V-10MH1F from STMicroelectronics is a 3.3V, 256 Kbit (32K x 8) Timekeeper SRAM which integrates a highly reliable, quartz-based oscillator and real-time clock (RTC) with a long-life lithium battery. This combination provides a stable and precise timekeeping solution, making it ideal for a wide range of applications that require accurate timekeeping along with non-volatile memory storage.

This particular model, the M48T37V-10MH1F, offers a 10MHz SRAM speed which ensures fast data access and processing, making it suitable for use in systems that require quick data retrieval and storage in conjunction with real-time clock functions. The device is housed in a 44-pin SOH (SOIC) package, which is compact enough for space-constrained applications while still providing easy integration into various system designs.

Key features of the M48T37V-10MH1F include:

• An integrated, power-fail deselect circuit which automatically switches to the battery supply during power failure, thus preserving data integrity.
• A built-in crystal which ensures high accuracy and stable timekeeping, with minimal drift over time and temperature variations.
• A programmable alarm function that can be set to trigger on a specific date, day of the week, hour, minute, or second, providing flexibility for time-based event management.
• A serial interface for RTC to facilitate easy integration with microcontrollers or other digital systems.
• Low power consumption, which is crucial for battery-backed memory and timekeeping devices.

The device's non-volatile storage capability ensures that data is retained for over 10 years in the absence of power. This feature, along with the device's robust timekeeping capabilities, makes the M48T37V-10MH1F an excellent choice for applications such as embedded systems, utility meters, industrial controllers, and other systems where maintaining accurate time and preserving data are critical.

STMicroelectronics' commitment to quality and reliability is evident in the design and manufacture of the M48T37V-10MH1F, offering designers a dependable timekeeping and memory solution that they can trust in their sophisticated electronic systems.
