PART NUMBER: KXTC9-2050 Rev. 2 Feb-2015 e N co ew m m D es en ig de ns d fo r ± 2g Tri-axis Analog Accelerometer Specifications 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. 36 Thornwood Dr. – Ithaca, NY 14850 tel: 607-257-1080 – fax:607-257-1146 www.kionix.com - info@kionix.com © 2015 Kionix – All Rights Reserved 679-4730:6142M-1502181628 Page 1 of 13 PART NUMBER: ± 2g Tri-axis Analog Accelerometer Specifications e N co ew m m D es en ig de ns d fo r KXTC9-2050 Rev. 2 Feb-2015 Functional Diagram 32K X Sensor Y Sensor Low Pass Filter Charge Amplifier Z Sensor 32K 32K 6 Output X 7 Output Y 8 Output Z Oscillator Vdd 1 GND 9 Logic 4 Enable N ot R 3 ST 36 Thornwood Dr. – Ithaca, NY 14850 tel: 607-257-1080 – fax:607-257-1146 www.kionix.com - info@kionix.com © 2015 Kionix – All Rights Reserved 679-4730:6142M-1502181628 Page 2 of 13 PART NUMBER: ± 2g Tri-axis Analog Accelerometer Specifications e N co ew m m D es en ig de ns d fo r KXTC9-2050 Rev. 2 Feb-2015 Product Specifications Table 1.

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. 36 Thornwood Dr. – Ithaca, NY 14850 tel: 607-257-1080 – fax:607-257-1146 www.kionix.com - info@kionix.com © 2015 Kionix – All Rights Reserved 679-4730:6142M-1502181628 Page 5 of 13 PART NUMBER: ± 2g Tri-axis Analog Accelerometer Specifications e N co ew m m D es en ig de ns d fo r KXTC9-2050 Rev. 2 Feb-2015 Table 3.

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. 36 Thornwood Dr. – Ithaca, NY 14850 tel: 607-257-1080 – fax:607-257-1146 www.kionix.com - info@kionix.com © 2015 Kionix – All Rights Reserved 679-4730:6142M-1502181628 Page 6 of 13 PART NUMBER: KXTC9-2050 Rev. 2 Feb-2015 e N co ew m m D es en ig de ns d fo r ± 2g Tri-axis Analog Accelerometer Specifications It is important the user determines the timing (TVdd_Off) and threshold (VDDLow) levels by evaluating the performance in the specific system for which the device will be incorporated. N ot R 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. 36 Thornwood Dr. – Ithaca, NY 14850 tel: 607-257-1080 – fax:607-257-1146 www.kionix.com - info@kionix.com © 2015 Kionix – All Rights Reserved 679-4730:6142M-1502181628 Page 7 of 13 PART NUMBER: ± 2g Tri-axis Analog Accelerometer Specifications e N co ew m m D es en ig de ns d fo r KXTC9-2050 Rev. 2 Feb-2015 Table 4.
