3-WIRE REAL-TIME CLOCK
S-35180A
Seiko Instruments Inc.
1
The S-35180A is a low-current-consumption 3-wire CMOS real-time clock IC
that features a wide operating voltage range (1.3 V to 5.5 V) and can be
driven on a variety of supply voltages, from a main supply to a backup
supply. The time keeping current consumption of 0.25
A and minimum
time keeping operation voltage of 1.1 V enable greatly increased battery
duration.
In a system that operates on a backup battery, the free register incorporated
in the real-time clock can be used for the user backup memory function.
The user register can hold data on a supply voltage as low as 1.2 V (min.),
so the data stored in the register before the main power supply was cut can
be called any time after the voltage is restored.
This product also includes a clock adjustment function that enables wide-
ranging correction of deviation in the frequency of the crystal oscillator at a
minimum resolution of 1 ppm. Also, by combining this function with a
temperature sensor, the clock adjustment value can be set in accordance
with changes in the temperature, which makes it possible to realize a clock
function that retains a high degree of accuracy regardless of temperature
variation.
