M41ST95Y*, M41ST95W

Square Wave Output
The M41ST95Y/W offers the user a programma-
ble square wave function which is output on the
SQW pin. RS3-RS0 bits located in 13h establish
the square wave output frequency. These fre-
quencies are listed in Table
6
. Once the selection
of the SQW frequency has been completed, the
SQW pin can be turned on and off under software
control with the Square Wave Enable Bit (SQWE)
located in Register 0Ah.

Square Wave Output
(Available only in 28-pin, 300mil SOIC (MX) package).
The M41ST95Y/W offers the user a special 32kHz
square wave function which is always output on
the F
32k
pin (Pin 21) as long as V
CC
≥
V
SO
, and the
oscillator is running (ST Bit = '0'). This function is
available within four seconds of initial power-up
and can only be disabled by setting the ST Bit to
'1,' or while the device is in back-up. If not used,
the F
32k
pin should be disconnected and allowed
to float.
