Description
The MSM62X42B is a bus-connection Microcomputer
peripheral IC of a Real Time Clock with built-in crystal
in the perpetual calendar which can be read and written
from a second unit. The interface between this IC and a
microcomputer uses 4 data buses, 4 address buses,
3 control buses and 2 chip selects and carries out
setting up, amending and reading time.
ALE input is available for 8048 system, 8051 system
or 8085 system and is used for other microcomputers
if this input is fixed at "H".
The clock function provides seconds, minutes, hours,
day of week, date, month, year, 12/24 hour selectable,
automatic leap year in the Christian Era and 30-second
compensation controlled by software. The periodical
interrupt function (or periodical waveform output) and the
STOP/START function of the clock are also provided.
The device is a silicon gate CMOS and the current
consumption is low. The built-in crystal oscillator is
32.768 kHz and battery backup operation is considered
