Application Notes for ROHM MEMs Accelerometers

Document Title Brief Description
Getting Started - KXTJ3 This application note will help developers quickly implement proof-of-concept designs using the KXTJ3 tri-axial accelerometer. Please refer to the KXTJ3 product specifications for additional implementation guidelines. While Kionix strives to ensure our accelerometers will meet design expectations by default, it is not possible to provide default settings to work in every environment. Depending on the intended application, it is very likely that some customisation will be required in order to optimise performance. We hope the information provided here will help the developer get the most out of the KXTJ3 accelerometer.
Getting Started - KX132 This application note will help developers quickly implement proof-of-concept designs using the KX132 tri-axis accelerometer. Please refer to the corresponding Technical Reference Manual document for available engines specific to your product and additional implementation guidelines. Kionix strives to ensure that our accelerometers will meet design expectations by default, but it is not possible to provide default setting to work in every environment. Depending on the intended application, it is very likely that some customisation will be required to optimiwe performance. The information provided here will help the developer get the most out of these tri-axis accelerometers.
Getting Started - KX134 This application note will help developers quickly implement proof-of-concept designs using the KX134 tri-axis accelerometer. Please refer to the corresponding Technical Reference Manual document for available engines specific to your product and additional implementation guidelines. Kionix strives to ensure that our accelerometers will meet design expectations by default, but it is not possible to provide default setting to work in every environment. Depending on the intended application, it is very likely that some customisation will be required to optimise performance. The information provided here will help the developer get the most out of these tri-axis accelerometers
Introduction to Advanced Data Path - KX13x The purpose of this application note is to help developers understand what can be done with the Advanced Data Path (ADP) supported by select parts in Kionix’s KX13x family of tri-axial accelerometers. The ADP is a combination of user tailorable frequency filters and a root mean square (RMS) calculator that provides the amplitude of acceleration within a desired bandwidth. The 16-bit ADP outputs for X, Y, and Z axes can be read out from the dedicated output registers, stored in the 512- byte FIFO buffer, and be routed to the Wake-Up and Back-to-Sleep engines. By setting desirable threshold amplitude and counter value, interrupts can be generated for specific motions, rotations, or vibrations. Two simple example cases are introduced to provide an intuitive image of the advantage of this new function.
Replacing KXTJ2 with KXTJ3 The purpose of this application note is to illustrate how the Kionix KXTJ3 digital accelerometer can replace an existing Kionix KXTJ2 digital accelerometer.
Transitioning to KX132-1211 Accelerometer The purpose of the application notes is to help customers to transition from KX022, KX023, KX112, KX122, KX123, KX124, KX126, KX127 accelerometers to KX132-1211 accelerometer.
Transitioning to KX134-1211 Accelerometer The purpose of the application notes is to help customers to transition from KX222-1054 and KX224-1053 accelerometers to KX134-1211 accelerometer.
