Maxim Integrated DS1742-070 Timekeeping RAM

The Maxim Integrated DS1742-070 is a high-performance, full-function timekeeping RAM module that combines a quartz crystal-controlled CMOS real-time clock (RTC) with a power-fail write-protect feature for static RAM. This innovative product is designed to maintain accurate time and date information, as well as to safeguard user data during power loss, making it an ideal component for a wide range of applications in computing, industrial, telecommunications, and embedded systems.

At the heart of the DS1742-070 lies a 64K x 8 non-volatile static RAM, providing ample storage for critical data. The real-time clock tracks seconds, minutes, hours, days, date, months, and years with leap-year compensation valid up to the year 2100. The clock accuracy is maintained by an onboard crystal oscillator, which ensures that timekeeping remains precise over the product's operating temperature range.

One of the key features of the DS1742-070 is its power-fail write protection capability. In the event of a power failure, the device automatically switches to a backup energy source, such as a lithium battery, to preserve the integrity of the data stored in RAM. This battery-backed operation is seamless and requires no user intervention, providing peace of mind that data will not be lost when the main power supply is interrupted.

The DS1742-070 is packaged in a 24-pin JEDEC standard configuration, making it easy to integrate into existing designs without the need for additional components or complex configurations. The module operates over a wide voltage range, typically from 4.5V to 5.5V, and features a low-power standby mode to conserve energy when the device is not in active use.

For developers and engineers looking to incorporate reliable timekeeping and data preservation into their systems, the Maxim Integrated DS1742-070 offers a robust and convenient solution. Its combination of real-time clock functionality and non-volatile storage ensures that critical time and data are always protected and available, even in the most demanding environments.
