DS1386/DS1386P

RAMified Watchdog Timekeeper

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

The DS1386 is a nonvolatile static RAM with a

full-function real-time clock (RTC), alarm,

watchdog timer, and interval timer that are all

accessible in a byte-wide format. The DS1386

contains a lithium energy source and a quartz

crystal, which eliminates the need for any external

circuitry. Data contained within 8k or 32k by 8-bit

memory and the timekeeping registers can be read

or written in the same manner as byte-wide static

RAM. The timekeeping registers are located in the

first 14 bytes of memory space. Data is maintained

in the RAMified timekeeper by intelligent control

circuitry, which detects the status of V_CCand write

protects memory when V_CCis out of tolerance. The

lithium energy source can maintain data and real

time for over ten years in the absence of V_CC.

Timekeeper information includes hundredths of

seconds, seconds, minutes, hours, day, date, month,

and year. The date at the end of the month is

automatically adjusted for months with less than 31

days, including correction for leap year.

ꢀ Watchdog Timer Restarts an Out-Of-

Control Processor

ꢀ Alarm Function Schedules Real-Time

Related Activities such as System Wakeup

ꢀ Programmable Interrupts and Square-

Wave Output

ꢀ All Registers are Individually Addressable

via the Address and Data Bus

ꢀ Interrupt Signals are Active in Power-

Down Mode

The RAMified timekeeper operates in either 24-

hour or 12-hour format with an AM/PM indicator.

The watchdog timer provides alarm interrupts and

interval timing between 0.01 seconds and 99.99

seconds. The real-time alarm provides for preset

times of up to one week. Interrupts for both

watchdog and RTC operate when the system is

powered down. Either can provide system “wake-

up” signals.

Pin Configurations appear at end of data sheet.
