Description

The DS1302Z trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. DS1302Z Features • Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year with Leap-Year Compensation Valid Up to 2100 • 31 x 8 Battery-Backed General-Purpose RAM • Serial I/O for Minimum Pin Count • 2.0V to 5.5V Full Operation • Uses Less than 300nA at 2.0V • Single-Byte or Multiple-Byte (Burst Mode) Data Transfer for Read or Write of Clock or RAM Data • 8-Pin DIP or Optional 8-Pin SO for Surface Mount • Simple 3-Wire Interface • TTL-Compatible (VCC = 5V) • Optional Industrial Temperature Range: -40°C to +85°C • DS1202 Compatible • Underwriters Laboratories (UL®) Recognized
