Product Description
The KXTC9-2050 is a Tri-axis, silicon micromachined
accelerometer with a full-scale output range of +/-2g (19.6 m/s/s).
The sense element is fabricated using Kionix’s proprietary plasma
micromachining process technology. Acceleration sensing is based
on the principle of a differential capacitance arising from
acceleration-induced motion of the sense element, which further
utilizes common mode cancellation to decrease errors from
process variation, temperature, and environmental stress. The
sense element is hermetically sealed at the wafer level by bonding
a second silicon lid wafer to the device using a glass frit. A
separate ASIC device packaged with the sense element provides
signal conditioning and self-test. The accelerometer is delivered in
a 3 x 3 x 0.9mm Land Grid Array (LGA) plastic package operating
from a 1.8 – 3.6V DC supply. The KXTC9 features a factory
programmable low pass filter.
There are 2 factory programmable modes of operation for the KXTC9:
Mode 00 – The Enable pin must be high for normal operation and low for power shutdown.
R
Mode 01 – The Enable pin must be low for normal operation and high for power shutdown.
N
ot
The KXTC9-2050 is factory programmed to be in MODE 00.

Power-On Reset (POR)
Proper functioning of power-on reset (POR) is dependent on the specific VDDLow and TVdd_Off profile of
individual applications. It is recommended to minimize VDDLow and maximize TVdd_Off. To assure
proper POR in all environmental conditions the application should be evaluated over the range of
VDDLow, TVdd_Off and temperature as POR performance can vary depending on these parameters. It is
also advised that the Rise or Fall be monotonic. Note that the outputs will not be stable until VDD has
reached its final value.
N
ot
R
Specific application testing will likely demonstrate POR performance regions for a proper POR trigger.
To assure POR trigger properly executes, setting operational thresholds consistent with Table 3 below
is suggested.
Example POR performance chart
As can be seen in this example POR performance chart, the time and Voltage to activate POR is
variable depending on the voltage and time as indicated by TVdd_Off max and min and VDDHigh and
VDDLow.

Notes:
1. VDD must always be monotonic ramps without ambiguous state.
2. TVdd rise or fall from 10% to 90% of final value needs to be ≤ TVdd Max.
3. In order to prevent the accelerometer from entering an ambiguous state, VDD needs to be
pulled down to GND (≤ VDDLow Min for a duration of time ≥ TVdd_Off Min)
4. Power will be maintained if VDD does not go below VDDHigh Max.
5. Between VDDHigh Max and VDDLow POR may occur.

The data provided by Kionix is intended for initial customer design guidance only. Kionix POR testing
looks at a finite number of test configurations. Each customer application will have varying input
sensor parameters (electrical, mechanical, and environmental) that will be different than the
configurations tested by Kionix. Each customer utilizing the sensor will need to properly validate the
sensor (including POR function) within their application under their specific use cases to ensure it
responds as required.

Application Design Equations
The bandwidth is determined by a factory programmable switched capacitor filter. The filter can be set at the
factory to be 2kHz, 1kHz, 500Hz, 100Hz, 50Hz, or no low pass filter. Alternatively, bandwidth can be reduced
by addition of a capacitor on the output pins 5, 6, and 7 according to the equation:
