DS1302+ General Description

The DS1302 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.

Key Features

Completely Manages All Timekeeping Functions
- Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of theWeek, and Year with Leap-Year Compensation Valid Up to 2100
- 31 x 8 Battery-Backed General-Purpose RAM
Simple Serial Port Interfaces to Most Microcontrollers
- Simple 3-Wire Interface
- TTL-Compatible (V_CC = 5V)
- Single-Byte or Multiple-Byte (Burst Mode)Data Transfer for Read or Write of Clock or RAM Data
Low Power Operation Extends Battery Backup Run Time
- 2.0V to 5.5V Full Operation
- Uses Less Than 300nA at 2.0V
8-Pin DIP and 8-Pin SO Minimizes Required Space
Optional Industrial Temperature Range: -40°C to +85°C Supports Operation in a Wide Range of Applications
Underwriters Laboratories^® (UL) Recognized
