Motorola Sensor Device Data
OUT Pin
The OUT pin normally provides a digital signal related to the
voltage applied to the voltage comparator and the threshold
level shifted into an 8-bit register from an external device. When
the device is placed in the standby mode the OUT pin is driven
high and will be clocked low when an overflow is detected from
a clock divider (divide by 16384) driven by the LFO. This allows
the OUT pin to wake up an external device such as an MCU.
Figure 3.

OUT Pin During Standby Mode
RST Pin
The RST pin is normally driven high and will be clocked low
when an overflow is detected from total clock divider (divide by
16,777,216) driven by the LFO. This allows the RST pin to reset
an external device such as an MCU. This pulse will appear on
the RST pin approximately every 52 minutes regardless of the
operating mode of the device. The pulse lasts for two cycles of
the LFO oscillator as shown in Figure 4. Since the RST pin is
clocked from the same divider string as the OUT pin, there will
also be a pulse on the OUT pin when the RST pin pulses every
52 minutes.
Figure 4. Pulse on RST Pin
S0 Pin
The S0 pin is used to select the mode of operation as shown
in Table 1.
The S0 pin contains an internal Schmitt trigger as part of its
input to improve noise immunity. The S0 pin has an internal pull-
down device in order to provide a low level when the pin is left
unconnected.
S1 Pin
The S1 pin is used to select the mode of operation, as shown
in Table 1.
The S1 pin contains an internal Schmitt trigger as part of its
input to improve noise immunity. This pin has an internal pull-
down device to provide a low level when the pin is left
unconnected.
The S1 pin also serves the purpose of enabling factory trim
and test of the device.
The higher V
programming voltage for the internal
EEPROM trim register is also supplied through the S1 pin.
DATA Pin
The DATA pin is the serial data in (SDI) function for setting
the threshold of the voltage comparator.
The DATA pin contains an internal Schmitt trigger as part of
its input to improve noise immunity. This pin has an internal pull-
down device to provide a low level when the pin is left
unconnected.
CLK Pin
The CLK pin is used to provide a clock used for loading and
shifting data into the DATA pin. The data on the DATA pin is
clocked into a shift register on the rising edge of the CLK pin
signal. The data is transferred to the D/A Register on the eighth
falling edge of the CLK pin. This protocol may be handled by the
SPI or SIOP serial I/O function found on some MCU devices.
The CLK pin contains an internal Schmitt trigger as part of its
input to improve noise immunity. The CLK pin has an internal
pull-down device to provide a low level when the pin is left
unconnected.
