DESCRIPTION
The M48T513Y/513V TIMEKEEPER
RAM is a
non-volatile 4,194,304 bit static RAM and real time
clock organized as 524,288 words by 8 bits. Sys-
tem integration features include Programmable
Alarms, Battery Low status Flag and a Power-on
Reset. The special 36-pin DIP package provides a
highly integrated battery back-up memory and real
time clock solution.
The memory locations providing user accessible
BYTEWIDE
clock information are in the bytes
with addresses 7FF1h and 7FF9h-7FFFh. These
clock locations contain the century, year, month,
date, day, hour, minute and second in 24 hour BCD
format. Corrections for 28, 29 (leap year, including
year 2000), 30, and 31 day months are made
automatically. Reference the M48T201 data sheet
for complete register map.
