STMicroelectronics M48T224-15MH5TR Real-Time Clock

The M48T224-15MH5TR is a high-performance, integrated real-time clock (RTC) module from STMicroelectronics, designed to offer precision timekeeping and memory backup in a wide range of computing, industrial, and consumer applications. This RTC module is particularly well-suited for systems that require reliable timekeeping, even in the absence of power.

Encased in a 44-pin SOH (SOP) package, the M48T224-15MH5TR combines a 22-bit binary counter, which acts as the timekeeping element, with a quartz crystal that ensures a high degree of accuracy. The module is characterized by a 4.5V to 5.5V operating voltage and a temperature range of -40°C to +85°C, making it robust for operation in various environmental conditions.

One of the key features of the M48T224-15MH5TR is its built-in 64 Kbits of static RAM, which provides convenient and reliable data storage. This non-volatile memory is maintained by an onboard battery, allowing the device to retain data and continue timekeeping for over 10 years in the absence of an external power supply. The module's integrated crystal and battery design simplifies the implementation process, as it does not require additional external components for its timekeeping functions.

The device offers a serial interface for communication, enabling easy integration with microcontrollers and other digital systems. Its functions include clock/calendar with subsecond precision, alarm interrupts, and programmable square wave output. These features make the M48T224-15MH5TR a versatile component for applications such as embedded systems, utility meters, POS terminals, and network servers.

Moreover, the M48T224-15MH5TR is designed with a watch-dog timer and a power-on reset function, which contribute to system reliability by providing additional layers of protection against system failures or malfunctions.

STMicroelectronics' commitment to quality ensures that the M48T224-15MH5TR meets the stringent requirements of industrial-grade components, providing a reliable and durable solution for timekeeping and memory backup purposes. With its comprehensive feature set and robust design, the M48T224-15MH5TR is an excellent choice for designers looking to incorporate a trusted RTC module into their systems.
