Question:
What about the Y2K problem
Answer:
Our Real-Time Clock outputs information consisting of the last two digits of the year. The S-35L12/L32
can use the register bits in its RTC to determine whether the year is 1900 or 2000 when the last two
digits change from 99 to 00. Most other RTCs, however, cannot determine whether the year is 1900 or
2000 when the last two digits change from 99 to 00. Thus, when this microcomputer is used, the user
must load year information for the RTC in a microcomputer to determine whether the year is 1900 or
2000. Accordingly, when the year reaches 2000, our RTC allows year information to operate normally
and be output as “00,” thereby preventing malfunctions.
There is no problem with the operation of the IC. If, however, peripheral circuits and software
developed by a client manage year information using the last two digits of the year, they may
malfunction. Thus, such devices should be checked.
