DS12885S+T&R

DS12885S+T&R Description

The DS12885S+T&R is a high-performance Real-Time Clock (RTC) and Calendar IC from Analog Devices Inc./Maxim Integrated, designed for precision timekeeping in embedded systems. Housed in a 24-SOIC package and supplied in Tape & Reel (TR), it integrates a parallel interface for seamless communication with microcontrollers. Operating within a 4.5V to 5.5V supply range, it ensures reliable performance in industrial and commercial environments (0°C to 70°C). The device includes 114B of NVSRAM for critical data retention, backed by a battery supply (2.5V–4V) for uninterrupted operation during power loss.

DS12885S+T&R Features

• Clock/Calendar Functionality: Supports 12/24-hour time format (HH:MM:SS) with leap year compensation and daylight savings adjustment.
• Advanced Features: Built-in alarm, square wave output, and NVSRAM for non-volatile storage.
• Low Power Consumption: Timekeeping current as low as 15mA at 4.5V–5.5V, ensuring energy efficiency.
• Robust Design: ROHS3 compliant, REACH unaffected, and MSL 1 (Unlimited) rated for extended shelf life.
• Battery Backup: Operates from 2.5V–4V for fail-safe timekeeping during main power failure.

DS12885S+T&R Applications

• Industrial Automation: Ideal for timestamping events in PLCs and control systems.
• Medical Devices: Ensures accurate time logging in patient monitoring equipment.
• Telecom Infrastructure: Synchronizes network switches and routers.
• Consumer Electronics: Powers clocks in smart appliances and POS terminals.
• Automotive Systems: Used in dashboard displays and diagnostic tools requiring persistent timekeeping.

Conclusion of DS12885S+T&R

The DS12885S+T&R stands out for its integration of RTC, NVSRAM, and alarm functions in a compact, surface-mount package. Its battery-backed operation, compliance with environmental standards, and broad voltage range make it a versatile choice for applications demanding precision, reliability, and data retention.
