FEATURES
§ Two 32-bit counters keep track of real-time
and elapsed time
§ Counters keep track of seconds for over 125
years
§ Battery powered counter counts seconds from
the time battery is attached until VBAT is less
than 2.5V
§ VCC powered counter counts seconds while
VCC is above VTP and retains the count in the
absence of VCC under battery backup power
§ Clear function resets selected counter to 0
§ Read/write serial port affords low pin count
§ Maximum current drain of less than 1 A
from VBAT pin when serial port is disabled
§ One byte protocol defines read/write, counter
address and software clear function
§ 8-pin DIP or optional 8-pin SOIC
§ Operating temperature range of -40°C to
+85°C
§ Reduced performance operation down to
VCC = 2.5V
§ Underwriters Laboratory (UL) recognized

DESCRIPTION
The DS1602 is a real-time clock/elapsed time counter designed to count seconds when VCC power is
applied and continually count seconds under battery backup power with an additional counter regardless
of the condition of VCC. The continuous counter can be used to derive time of day, week, month, and year
by using a software algorithm. The VCC powered counter will automatically record the amount of time
that VCC power is applied. This function is particularly useful in determining the operational time of
equipment in which the DS1602 is used. Alternatively, this counter can also be used under software
control to record real-time eve nts. Communication to and from the DS1602 takes place via a 3-wire serial
port. A 1-byte protocol selects read/ write functions, counter clear functions and oscillator trim. A low
cost 32.768kHz crystal attaches directly to the X1 and X2 pins. If battery powered-only operation is
desired, the VBAT pin must be grounded and the VCC pin must be connected to the battery.
