The KXCNL-1010 is a tri-axis +/-2g, +/-4g, +/-6g, or +/-8g silicon micromachined accelerometer with
integrated programmable state machines. 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 intelligent userprogrammable state machines. The accelerometer is delivered in a 3 x 3 x 0.9 mm LGA plastic
package operating from a 1.8 – 3.6V DC supply. I2C interface is used to communicate to the chip to
load state programs, configure settings, and check updates to the acceleration data.

f
A unit of acceleration equal to the acceleration of gravity at the earth's surface.
m
1g 9.8 2
s
One thousandth of a g (0.0098 m/ s2) is referred to as 1 milli-g (1 mg).
Sensitivity
The sensitivity of an accelerometer is the change in output per unit of input acceleration at nominal
Vdd and temperature. The term is essentially the gain of the sensor expressed in counts per g
(counts/g) or LSB’s per g (LSB/g). Occasionally, sensitivity is expressed as a resolution, i.e. milli-g
per LSB (mg/LSB) or milli-g per count (mg/count). Sensitivity for a given axis is determined by
measurements of the formula:
Sensitivit y
Output @ 1g Output @ 1g
2g
The sensitivity tolerance describes the range of sensitivities that can be expected from a large
population of sensors at room temperature and over life. When the temperature deviates from
room temperature (25ºC), the sensitivity will vary by the amount shown in Table 1.
Zero-g offset
ot
R
Zero-g offset or 0-g offset describes the actual output of the accelerometer when no acceleration is
applied. Ideally, the output would always be in the middle of the dynamic range of the sensor
(content of the OUTX, OUTY, OUTZ registers = 00h, expressed as a 2’s complement number).
However, because of mismatches in the sensor, calibration errors, and mechanical stress, the
output can deviate from 00h. This deviation from the ideal value is called 0-g offset. The zero-g
offset tolerance describes the range of 0-g offsets of a population of sensors over the operating
temperature range.
N
Self-test
Self-test allows a functional test of the sensor without applying a physical acceleration to it. When
activated, an electrostatic force is applied to the sensor, simulating an input acceleration. The
sensor outputs respond accordingly. If the output signals change within the amplitude specified in
Table 1, then the sensor is working properly and the parameters of the interface chip are within the
defined specifications.

f
The sense element is fabricated using Kionix’s proprietary plasma micromachining process
technology. This process technology allows Kionix to create mechanical silicon structures which
are essentially mass-spring systems that move in the direction of the applied acceleration.
Acceleration sensing is based on the principle of a differential capacitance arising from the
acceleration-induced motion. Capacitive plates on the moving mass move relative to fixed
capacitive plates anchored to the substrate. The sense element is hermetically sealed at the wafer
level by bonding a second silicon lid wafer to the device using a glass frit.
ASIC interface
A separate ASIC device packaged with the sense element provides all of the signal conditioning
and communication with the sensor. The complete measurement chain is composed by a low-noise
capacitance to voltage amplifier which converts the differential capacitance of the MEMS sensor
into an analog voltage that is sent through an analog-to-digital converter. The acceleration data may
be accessed through the I2C digital communications provided by the ASIC. In addition, the ASIC
contains all of the logic to allow the user to choose data rates, g-ranges, filter settings, and interrupt
logic. Plus, there are two programmable state machines which allow the user to create unique
embedded functions based on changes in acceleration.
Factory calibration
N
ot
R
Kionix trims the offset and sensitivity of each accelerometer by adjusting gain (sensitivity) and 0-g
offset trim codes stored in non volatile memory (OTP). Additionally, all functional register default
values are also programmed into the non volatile memory. Every time the device is turned on or a
software reset command is issued, the trimming parameters and default register values are
downloaded into the volatile registers to be used during active operation. This allows the device to
function without further calibration.

DR_EN = 1 Data Ready signal is connected to INT1 and overrides any other
interrupt settings.
IEA controls the polarity of interrupt signals.
IEA = 0 – Interrupt signals active LOW.

IEL controls the latching state of interrupt signals.

IEA = 1 – Interrupt signals are pulsed.
or
IEA = 1 – Interrupt signals active HIGH.
INT2_EN enables the INT2 pin.
INT2_EN = 0 – INT2 signal disabled. INT2 pin in high-Z state.
INT2_EN = 1 – INT2 signal enabled and signal is fully functional. \CNTL1, IEN must
be taken into account also.
INT1_EN enables the INT1/DRDY pin.
INT1_EN = 0 – INT1/DRDY signal disabled. INT1/DRDY pin in high-Z state.
INT1_EN = 1 – INT1/DRDY signal enabled and signal is fully functional. \CNTL1, IEN

VFILT enables or disables the Vector Filter.
VFILT = 0 – Vector filter disabled.
VFILT = 1 – Vector filter enabled.
STP controls the activation of self test.
STP = 0 – Normal operation with no Self Test effect.
STP = 1 – Positive Self Test effect.
STRT performs a Soft Reset of the KXCNL if set to a 1. Similar to POR, defaults for
registers are loaded from internal memory. Once the reset is complete, this bit is
set to 0.

/THRS3
Read/write register that contains the common threshold for overrun detection. This threshold is
always unsigned (abs) regardless of /SETTy, ABS settings and is common to both State Programs.
If any axis value exceeds /THRS3 limit (regardless /TAMxAy status), then the RESET action
(/PPy=/RPy) and the RESET Initial Start task immediately occur.

Offset correction
The following three registers contain up to 8-bits of offset correction for each axis. Because there
are typically offset drifts after solder reflow, there is sometimes a need to zero or normalize the
outputs for better application performance. These signed offset correction values are multiplied by
2 and subtracted from the outputs provided to the State Programs and to the streaming 12-bit data
registers.

P_DET is the peak detection control bit.
P_DET = 0 peak detection disabled.
P_DET = 1 peak detection enabled in State Program 2.
THR3_SA controls the reset action when Threshold 3 is exceeded and mask is /SA2.
THR3_SA = 0 no action.
THR3_SA = 1 Exceeding Threshold 3 immediately triggers Reset action if mask is
/SA2 (/MASA2 == 1). Every sample and every axis is tested to determine if it
exceeds Threshold 3 regardless of the /TAMxA2 value. /THRS3 (register) limit is
common for both State Programs.
ABS is the peak absolute threshold enable/disable control.
ABS = 0 unsigned thresholds. Thresholds are symmetric across the zero line.
ABS = 1 signed thresholds in State Program 2. Thresholds are sign dependent.
RADI controls difference data mode. Only for State Program 2.
RADI = 0 use raw data
RADI = 1 use difference data in State Program 2.
R
D_CS DIFF2 or constant shift mode. Only for State Program 2.
D_CS = 0 DIFF2
D_CS = 1 constant shift for DIFF definition

THR3_MA controls the reset action when Threshold 3 is exceeded and mask is /MA2.
THR3_MA = 0 no action.
THR3_MA = 1 Exceeding Threshold 3 immediately triggers Reset action if mask is
/SA2 (/MASA2 == 0). Every sample and every axis is tested to determine if it
exceeds Threshold 3 regardless of the /TAMxA2 value. /THRS3 (register) limit is
common for both State Programs.
R_TAM is the temporary axis mask and peak state flag release.
R_TAM = 0 no changes for /TAMxA2.
R_TAM = 1 /TAMxA2 released to default after every valid NEXT condition.
SITR is the temporary axis mask and peak state flag release.
SITR = 0 no actions.
SITR = 1 STOP and CONT commands proceeds also output as OUTC command.
