Maxim Integrated DS17885S-3+ Real-Time Clock

The DS17885S-3+ from Maxim Integrated is a highly integrated, full-featured real-time clock (RTC) module that provides a comprehensive timekeeping solution for a wide range of applications. This RTC is designed to maintain accurate time and date information, measured in terms of seconds, minutes, hours, days, weeks, months, and years. Additionally, it includes extra features such as an alarm function and programmable square-wave output, making it a versatile choice for embedded systems that require reliable time management.

The DS17885S-3+ integrates a quartz crystal and a lithium battery, which ensures that timekeeping continues even when the main power supply is interrupted, with a typical battery life that can last for years. The device follows the industry-standard footprint and pinout of the IBM AT computer, which makes it a drop-in replacement for other similar RTCs.

Key features of the DS17885S-3+ include:

• Integrated temperature-compensated crystal oscillator (TCXO) for high accuracy and stable timekeeping
• Low-power operation that extends battery life for long-term reliability
• Automatic leap year correction up to the year 2100, ensuring accuracy for decades to come
• Serial interface for easy communication with microcontrollers and other digital systems
• Dual alarms with interrupt capabilities, allowing for scheduled events or wake-up signals
• Programmable square-wave output for timer functions or clock reference signals
• 56-byte, battery-backed NV SRAM for storage of critical data that must be preserved during power loss

This RTC is ideal for applications such as embedded systems, industrial controllers, data loggers, and any other systems that require accurate timekeeping or timed operations. The DS17885S-3+ is available in a surface-mount package, ensuring ease of integration into modern PCB designs.

With its robust feature set and proven reliability, the Maxim Integrated DS17885S-3+ Real-Time Clock is a top choice for designers looking to incorporate a trusted timekeeping solution into their projects.
