**IBM AT: MC146818 Real Time Clock                                 <84
***Info:
The MC146818  Real-Time Clock  plus RAM is  a peripheral  device which
includes   the   unique   MOTEL   concept   for   use   with   various
microprocessors,  microcomputers,  and  larger computers.   This  part
combines  three unique  features:  a complete  time-of-day clock  with
alarm and one hundred year calender, a programmable periodic interrupt
and square-wave generator,  and 50 bytes of low-power  static RAM. The
MC146818  uses high-speed  CMOS  technology to  interface  with 1  MHz
processor busses, while consuming very little power.

The  Real-Time Clock  plus RAM  has two  distinct uses.  First,  it is
designed  as a  battery powered  CMOS part  (in an  otherwise NMOS/TTL
system) including  all the common battery backed-up  functions such as
RAM, time,  and calendar.  Secondly, the  MC146818 may be  used with a
CMOS  microprocessor  to  relieve  the  software  of  the  timekeeping
workload  and to  extend  the available  RAM  of an  MPU  such as  the
MC146805E2
