M48T58-70PC1

The M48T58-70PC1 is a real-time clock (RTC) chip that combines a calendar clock with 512K bits of static RAM (SRAM) to provide a highly versatile clock-calendar and RAM system. With its integrated SRAM, the M48T58-70PC1 can not only keep track of the current time, but also store data that are used for power management and other operations. Furthermore, it has two separate power-on / power-off reset signals, making it suitable for applications where the system needs to be powered on or restarted at specified times.

The M48T58-70PC1 consists of a real-time clock and static RAM. The real-time clock is a full-sized, self-contained clock oscillator, providing a time-keeping accuracy of ±150 ppm. It is controlled by a 32-bit microcontroller. The SRAM is capable of storing 512K bits, which is divided into 32K words of 16 bits each. The M48T58-70PC1 features an integrated nonvolatile RAM (NVRAM) and real-time clock registers, allowing the clock to store the year, month, and day information. This information is used to determine the current weekday and weekend days.

The M48T58-70PC1 has two separate power-on / power-off reset signals. The RTC stores the current time and calendar, as well as the current operating state of the system. When the system is powered on, the RTC will use the stored data to initialize the system. When the system is powered off, the RTC will save the current time and calendar information in its registers, allowing it to be quickly recovered when power is restored. The M48T58-70PC1 is designed to withstand shock and vibration, making it suitable for use in factory automation and other applications with high-vibration environments.

The M48T58-70PC1 is used in embedded systems to store real-time clock and calendar data. It can also be used for power management and other operations. The SRAM can be used to store application data that needs to be retained when the system is powered off and on. The two separate power-on / power-off reset signals make it suitable for applications that require the system to be powered on or restarted at specified times. The device is designed to be highly reliable and easy to use, making it an excellent choice for use in embedded systems.

In summary, the M48T58-70PC1 is an ideal real-time clock (RTC) chip for embedded system applications. It integrates a real-time clock and static RAM, allowing the system to store data and calendar information. The two separate power-on / power-off reset signals make it suitable for applications that require the system to be powered on or restarted at specified times. It is reliable, easy to use, and highly accurate, making it an excellent choice for applications requiring a real-time clock and calendar data.
