ACCELEROMETER
The TWR-S08 applies the MMA7361L, 3-axis, analog accelerometer for tilt and motion-sense
applications. The accelerometer supports 2 user selectable sensitivities - 1.5g / 6g. The
SLEEP* input allows the device to be placed in a low-power mode. Separate X-, Y-, and Z-
axis readings are routed to the MCU. Output filtering is applied to remove fast transients.
Configuration
Accelerometer sensitivity configuration is controlled manually using option select header JP2.
The SLEEP* input is configurable manually or under MCU control. Figure 7 below shows the
setting to configure the accelerometer output.

Cut-traces on the accelerometer output signals allow the user to disconnect the accelerometer
output if necessary. Once cut, simply install a 1206 sized, 0-ohm resistor to reconnect the
accelerometer output. Figure 8 below shows how the accelerometer output connects to the
target MCU.
