REAL TIME CLOCK WITH PERIODIC AND ALARM OUTPUT

DESCRIPTION

The MSM6542 is a perpetual-calendar-based

real time clock with an alarm function which

can read and write data in units of seconds. It

can be connected to various buses and can

function as a peripheral IC of a microcom-

puter.

bus pins, three control bus pins, and two chip

select pins. These pins are used to write or

read data from the clock, alarm, and control

registers, or to modify the data.

The MSM6542 has an address latch enable

(ALE) input pin, allowing the data bus and

address bus to be shared. When the ALE

input pin is kept high, the data bus and ad-

dress bus can be exclusively used.

The clock ranges are seconds, minutes, hours,

days, months, years, and days of the week.

Thealarmrangesareseconds,minutes,hours,

days, months, and days of the week.

Other functions of the MSM6542 are: a 30-

second adjustment, stop and restart of clock,

dataregistersasRAM,anddataregister(RAM)

protection.

An event trigger is generated when the time

matches the specified time and an alarm oc-

curs or when the clock counter generates a

carry. The interrupt and pulse outputs are

provided for each of an alarm and a carry.

The CMOS circuitry used in the MSM6542

affords low power dissipation. The crystal

oscillator operates at 32.768 kHz. Provisions

for backup time keeping are included.

An interface with a microcomputer is imple-

mented by four data bus pins, four address

bus

FEATURES

•

Realtimeclockprovidingseconds,minutes,
