Rochester Electronics DS1672S-3 Environmental and export classification status description

Overview of DS1672S-3 The DS1672S-3 is a real-time clock (RTC) device with an integrated temperature sensor, memory, and a watchdog timer manufactured by Maxim Integrated (now part of Analog Devices). It is designed for applications that require accurate timekeeping while also enabling additional functions like memory storage and temperature monitoring. Functions 1. Real-Time Clock: The DS1672S-3 provides accurate timekeeping with year, month, date, day, hour, minute, and second. 2. Temperature Measurement: It integrates a temperature sensor that can measure ambient temperature ranging from -40°C to +125°C. 3. Memory: The device includes a small amount of non-volatile memory (NVRAM) that can be used for data storage. 4. Watchdog Timer: It features a watchdog timer that helps ensure system reliability by resetting the system if it becomes unresponsive. 5. Low Power Consumption: The DS1672S-3 is designed to operate under low power conditions, making it suitable for battery-powered applications. Applications - Consumer Electronics: Used in clocks, timers, and appliances that require timekeeping functionality. - Industrial Equipment: Incorporated in systems needing real-time data logging along with environmental monitoring (temperature). - Data Loggers: Utilized in devices that record time-stamped data such as environmental variables. - Telecom: Applied in telecommunications for scheduling and timestamping events. - Embedded Systems: Commonly used in microcontroller applications for adding RTC features. Alternative Components 1. DS3231: Another RTC with a built-in temperature sensor that provides higher accuracy. 2. MCP79410: An RTC with battery backup and integrated EEPROM. 3. PCF8523: A low-power RTC with programmable alarm functions. 4. RV-3028-C7: A high-precision RTC that offers temperature compensation. Embedded Modules While the DS1672S-3 is typically used as a standalone IC, various development boards and modules are available that incorporate similar RTC functionalities: - RTC Modules: Various RTC breakout boards designed for Arduino and Raspberry Pi platforms (often using components like DS3231 or DS1307). - Embedded Systems Board: Boards such as the STM32 or Arduino development kits often include RTC functionality through various compatible ICs/modules. Related Q&A 1. Q: What is the main advantage of using an RTC like the DS1672S-3? - A: The main advantages include precise timekeeping capabilities, integration of additional features like memory and temperature sensing, and low power consumption, making it suitable for a variety of embedded applications. 2. Q: Can you use the DS1672S-3 without a backup battery? - A: No, the DS1672S-3 relies on a backup battery to maintain time when the main power is lost.
