DS1385/DS1387
RAMified Real Time Clock 4K x 8
DS1385/DS1387
012496 1/20
FEATURES
Upgraded IBM AT computer clock/calendar with
4K x 8 extended RAM
Totally nonvolatile with over 10 years of operation in
the absence of power
Counts seconds, minutes, hours, day of the week,
date, month and year with leap year compensation
Binary or BCD representations of time, calendar and
alarm
12– or 24–hour clock with AM and PM in 12–hour
mode
Daylight Savings Time option
Multiplex bus for pin efficiency
Interfaced with software as 64 user RAM locations
plus 4K x 8 of static RAM
– 14–bytes of clock and control registers
– 50–bytes of general purpose RAM
– 4K x 8 SRAM accessible by using separate con-
trol pins
Programmable square wave output signal
Bus–compatible interrupt signals (IRQ)
Three interrupts are separately software–maskable
and testable:
– Time–of–day alarm once/second to once/day
– Periodic rates from 122
μ
s to 500 ms
– End–of–clock update cycle
Available as chip (DS1385 or DS1385S) or stand
alone module with embedded lithium battery and
crystal (DS1387)
