MSM62X42B  
REAL TIME CLOCK IC WITH BUILT-IN CRYSTAL  
DESCRIPTION  
The MSM62X42B is a bus-connection Micro-  
computer peripheral IC of a Real Time Clock  
with built-in crystal in the perpetual calendar  
which can be read and written from a second  
unit. The interface between this IC and a  
microcomputer uses 4 data buses, 4 address  
buses, 3 control buses and 2 chip selects and  
carries out setting up, amending and reading  
time.  
The clock function provides seconds, min-  
utes, hours, day of week, date, month, year,  
12/24 hour selectable, automatic leap year in  
the Christian Era and 30-second compensa-  
tion controlled by software. The periodical  
interrupt function (or periodical waveform  
output) and the STOP/START function of the  
clockarealsoprovided. Thedeviceisasilicon  
gate CMOS and the current consumption is  
low. The built-in crystal oscillator is 32.768  
kHz and battery backup operation is consid-  
ered.  
ALE input is available for 8048 system, 8051  
system or 8085 system and is used for other  
microcomputers if this input is fixed at "H".  
FEATURES  
32.768kHz built-in crystal oscillator  
(2 ranks of ±10PPM and ±50PPM ---  
DIP)  
(2 ranks of ±20PPM and ±50PPM ---  
SOP)  
Real time clock of second, minute, date,  
month, year and day of week  
Interface corresponding to microcom-  
puter bus  
30-second compensation controlled by  
software  
STOP/START function for clock  
12/24 hour selectable  
AEL input for 8048 system, 8051 system  
or 8085 system (when a microcomputer  
does not provide the ALE output, fix the  
AEL input at "H".)  
Low current consumption for CMOS  
device  
Low STANDBY voltage and small  
STANDBY current  
18-pin plastic DIP(DIP18-P-300)  
24-pin plastic SOP  
Periodical interrupt function (or  
periodical waveform output) for alarm
