Maxim Integrated DS1251YP-070 Nonvolatile Timekeeping RAM

The DS1251YP-070 from Maxim Integrated is a high-performance, full-featured 3.3V or 5V p-Power nonvolatile timekeeping RAM. This innovative product integrates a full-function real-time clock, 128k x 8 nonvolatile static RAM, power-fail control circuit, and battery into a single 32-pin EDIP package. It is designed to maintain data and real-time clock accuracy in the absence of system power, making it an ideal solution for a wide range of applications that require reliable data and timekeeping capabilities even during power outages.

The real-time clock in the DS1251YP-070 provides information on the year, month, date, day, hours, minutes, and seconds in binary-coded decimal (BCD) format. An important feature of this product is its automatic leap year compensation, which is valid up to the year 2100. This ensures that timekeeping remains accurate without the need for manual adjustments for leap years.

One of the key features of the DS1251YP-070 is its integrated lithium energy source and control circuitry, which constantly monitors VCC for an out-of-tolerance condition. When such a condition occurs, the device automatically switches to its backup power supply, thus preserving the integrity of the data and clock. The energy source is capable of maintaining data and real-time clock accuracy for over 10 years in the absence of external power.

Furthermore, the DS1251YP-070 offers a write protection mechanism that ensures data integrity by preventing accidental data corruption during low-voltage conditions. This product is fully compatible with the JEDEC standard 32-pin DIP sockets and is recognized under the JEDEC standard number MO-142DD.

With its robust feature set, the DS1251YP-070 is perfect for applications in telecommunications, embedded systems, industrial control systems, and any other systems that need to maintain accurate time and date information through power losses. Maxim Integrated's commitment to quality and reliability makes the DS1251YP-070 a trusted component for maintaining critical data and timekeeping functions in your electronic designs.
