DESCRIPTION
The M48T39Y TIMEKEEPER
RAM is a non-vol-
atile 262,144 bit static RAM and real time clock or-
ganized as 32,768 words by 8 bits. System
integration
features
include
Alarms, Watchdog Timer and Interval Timer. The
special 32-pin DIP package provides a highly inte-
grated battery back-up memory and real time
clock solution.
