General Description
The DS1318 parallel-interface elapsed time counter
(ETC) is a 44-bit counter that maintains the amount of
time that the device operates from main and/or backup
power or during an external event. The internal
frequency of the counter clock is 4.096kHz, which pro-
vides a 244s resolution and a maximum count of over
136 years. A built-in power-sense circuit detects power
failures, automatically switches to the backup supply,
and controls the timer. If an external event timer is
desired, the control input EXT can control the counter
operation. An open-drain output provides an interrupt,
and a square-wave output provides a programmable
square wave. The DS1318 is accessed through a byte-
wide parallel interface, and operates over the industrial
temperature range.
