1339-31DVGI8

Real-time clocks are typically used in data logging and time-stamp applications where the most accurate knowledge of time is required. Despite the miniaturization of today’s integrated circuits, the need for extremely accurate timing solutions in a range of applications, from timing data loggers to automotive systems, is becoming increasingly important. The 1339-31DVGI8 is a real-time clock designed with the most precise timestamps imaginable in order to meet these requirements.

The 1339-31DVGI8 is a low power, high-precision RTC chip from Ramtron that is specifically targeted for use in harsh environments. It combines a 32.768 kHz watch crystal oscillator with an I2C digital interface, providing accuracy of ±500ppm over the temperature range of -40°C to +85°C.

The 1339-31DVGI8 is designed for use in a variety of applications including wireless sensor networks, battery powered systems, automotive telemetry and communication systems, as well as data logging and tracking systems. It has an easy-to-use I2C interface, which allows it to be connected to a microcontroller or other system components with minimal configuration. The 1339-31DVGI8 also features programmable alarms, a wide range of date, time, and clock functions, and a battery backup mode.

The 1339-31DVGI8 works by using a 32kHz oscillator as a reference frequency. This frequency is then divided down to an exact and precise 1Hz clock. This clock is used to maintain the date and time, which can be accessed and manipulated using the I2C interface.

The 1339-31DVGI8 is also capable of tracking long-term time intervals. This is done by counting the 1Hz signals, and then storing the current time when a count reaches a predetermined threshold. This allows the RTC to easily keep track of long-term time intervals, such as months or years.

The 1339-31DVGI8 is also capable of setting up alarms. When an alarm occurs, a signal can be sent out to alert the user of the event. The alarm can be programmed to a specific time, or can be set to a specific day or date. Additionally, the alarm can be programmed to a certain frequency, allowing the user to set up periodic alarms.

In addition to its precise timing, the 1339-31DVGI8 also features a very low power consumption of 8µA at 3V. Its small size also allows it to be used in areas where size is a major concern, such as embedded systems or portable devices.

The 1339-31DVGI8 is a very precise and reliable RTC chip that is designed to provide accurate timing solutions in a range of applications. Its versatility and low power consumption make it an ideal choice for data logging, tracking and time-stamp applications.
