The DS1557P-70IND clock is a high-performance real time clock that effectively and accurately tracks time. It’s an industrial-grade device designed for medical, industrial and automotive applications. The DS1557P-70IND offers high-precision time measurable, with an accuracy of ±30ppm per year over temperature.

The DS1557P-70IND is based on DS1557P’s industrial-grade real time clock, but with a few enhancements. It is a low-power device, consuming only 0.7 mA of power at 3.3V and 0.8 mA when operating at 5V. In addition, it offers high thermal stability and reliability, with a maximum operating temperature range of –40°C to +125°C. The clock includes a crystal-oscillator and frequency drift compensation circuitry that allows for improved temperature tolerance and long term accuracy over temperature and voltage variations.

The most notable feature of the DS1557P-70IND is its low-power operation. Operating at only 0.7mA, the clock consumes significantly less energy than competing products, enabling longer battery life and lower maintenance costs. Additionally, the clock is equipped with intelligent power management, allowing it to remain in low-power mode when not in active use.

The DS1557P-70IND clock also offers a robust set of features to ensure stable, reliable and accurate time measurements. It features 1 second resolution and an adjustable frequency output of up to 297Hz which enables precise time-stamping, logging and monitoring. It also features an internal frequency trimming control for improved accuracy and timing stability. Furthermore, it supports both I2C and SPI serial communication protocols for easy integration into existing systems and it is designed to meet the demanding requirements of industrial and automotive applications.

The operating principle of the DS1557P-70IND is based on an oscillator crystal. Inside the clock, the crystal works with a counter and a divider circuit to accurately count and measure seconds, minutes, hours, and days. The frequency generated by the crystal is divided down by the counter and the result is used to accurately track time. The oscillator is also temperature compensated to ensure reliable time-keeping even under varying temperatures.

Overall, the DS1557P-70IND is an excellent choice for industrial and automotive applications that require precise and reliable time measurement. It is a low-power device, with a maximum operating current of only 0.7mA, and it also has an adjustable frequency output, internal frequency trimming control, I2C and SPI communication protocols and temperature compensation. Additionally, it meets the demanding requirements of industrial and automotive applications, making it a suitable choice for these applications.
