RTC with Constant-Voltage Trickle Charger  
General Description  
Features  
The DS12R885 is a functional drop-in replacement for  
the DS12885 real-time clock (RTC). The device pro-  
vides an RTC/calendar, one time-of-day alarm, three  
maskable interrupts with a common interrupt output, a  
programmable square wave, and 114 bytes of battery-  
backed static RAM. The date at the end of the month is  
automatically adjusted for months with fewer than 31  
days, including correction for leap years. It also oper-  
ates in either 24-hour or 12-hour format with an AM/PM  
indicator. A precision temperature-compensated circuit  
♦ Trickle-Charge Capability for a Rechargeable  
Battery or Super Cap  
♦ Selectable Intel or Motorola Bus Timing  
♦ RTC Counts Seconds, Minutes, Hours, Day, Date,  
Month, and Year with Leap-Year Compensation to  
2100  
♦ Interrupt Output with Three Independently  
Maskable Interrupt Flags  
♦ Time-of-Day Alarm is Once-per-Second to Once-  
per-Day  
♦ Periodic Rates from 122µs to 500ms  
monitors the status of V . If a primary power failure is  
CC  
detected, the device automatically switches to a back-  
up supply. The V  
pin supports a rechargeable  
BACKUP  
battery or a super cap and includes an integrated,  
always enabled trickle charger. The DS12R885 is  
accessed through a multiplexed byte-wide interface,  
which supports both Intel and Motorola modes. The  
DS12CR887 and DS12R887 integrate the DS12R885  
die with a crystal and battery.  
♦ End-of-Clock Update Cycle Flag  
♦ 14 Bytes of Clock and Control Registers  
♦ 114 Bytes of General-Purpose RAM with Clear Input  
♦ Programmable Square-Wave Output  
♦ Automatic Power-Fail Detect and Switch Circuitry  
♦ +5.0V or +3.3V Operation

♦ Industrial Temperature Range
