Maxim Integrated DS14285SN/T&R Real-Time Clock

The Maxim Integrated DS14285SN/T&R is a high-performance, low-power real-time clock (RTC) with a full binary-coded decimal (BCD) clock/calendar and 114 bytes of NV SRAM. This integrated circuit is designed to provide precise time and date information ranging from seconds to years, and it is particularly suitable for applications requiring long-term battery-backed timekeeping, such as embedded systems, utility meters, and data loggers.

One of the key features of the DS14285SN/T&R is its ability to maintain time accuracy while operating in a low-power mode. This makes it an ideal choice for battery-powered applications where power efficiency is critical. The device is also equipped with an integrated crystal oscillator, which simplifies the design and reduces the external component count, saving both space and cost.

The RTC provides a simple and efficient interface for microprocessors via a multiplexed byte-wide interface. This interface allows for easy integration into existing designs, minimizing development time and complexity. The DS14285SN/T&R also features an automatic power-fail detect and switch circuitry, which ensures that timekeeping continues uninterrupted in the event of a primary power failure, by automatically switching to a backup power supply.

Furthermore, the device includes a programmable periodic or single alarm, which can be set to trigger on a variety of conditions, such as a specific time of day or a particular date. This feature is particularly useful for scheduling tasks or reminding systems to perform certain actions at predetermined times.

The DS14285SN/T&R is provided in a surface-mount SN package and is supplied on tape and reel (T&R), which facilitates automated assembly processes, making it a convenient choice for mass production environments. With its robust timekeeping capabilities and easy integration, the Maxim Integrated DS14285SN/T&R RTC is a reliable and cost-effective solution for a wide range of time-sensitive applications.

With Maxim Integrated's reputation for quality and reliability, the DS14285SN/T&R is a secure choice for designers looking to incorporate accurate timekeeping functions into their systems without compromising on power efficiency or design simplicity.
