Maxim Integrated DS1302SN-16 Real-Time Clock (RTC) Module

The Maxim Integrated DS1302SN-16 is a versatile Real-Time Clock (RTC) module designed for applications requiring precise timekeeping and data management. This compact, low-power device integrates a real-time clock/calendar and 31 bytes of static RAM, providing a full binary-coded decimal (BCD) clock/calendar with 56-byte, battery-backed, nonvolatile (NV) RAM for data storage.

Key Features

• Real-Time Clock/Calendar: Tracks time in hours, minutes, and seconds, along with the day, month, and year. It is designed to handle leap years and can operate in either 24-hour or 12-hour format with an AM/PM indicator.
• Low Power Consumption: Suitable for battery-powered applications, the DS1302SN-16 consumes less power and offers a trickle-charge capability to maintain the backup battery charge level.
• Serial Interface: The device communicates with a microcontroller via a simple serial interface, which minimizes the number of pins required for operation and simplifies the overall design.
• Nonvolatile RAM: Features 31 bytes of static RAM, allowing for storage of critical data that must be preserved during power loss, without the need for an external battery.
• Dual Power Supply Pins: This RTC module operates on dual power supply pins for primary and backup power sources, ensuring continuous timekeeping and data retention.
• Compact Surface-Mount Package: The DS1302SN-16 comes in a space-saving, 16-pin SO (small outline) package, making it ideal for space-constrained applications.

Applications

The DS1302SN-16 is suitable for a wide range of applications, including:

• Embedded systems
• Utility meters
• Consumer electronics
• Handheld devices
• Industrial controllers
• Office automation

Maxim Integrated's DS1302SN-16 RTC module is a reliable and cost-effective solution for systems that require accurate timekeeping and data storage, ensuring that your application maintains accurate time and data integrity even in the event of a power outage.
