ROHM affiliate KIONIX's KX132-1211 and KX134-1211 3-axis accelerometer sensors can perform noise filtering autonomously instead of an MCU.


On the 5th, KIONICS of ROHM Group announced that it has developed the 3-axis accelerometer sensors 'KX132-1211' and 'KX134-1211' suitable for applications requiring low-power, high-precision motion sensing.

Equipped with KIONIX's proprietary ADP (Advanced Data Path) function, the KX132-1211 and KX134-1211 can independently perform sensor signal processing and noise filtering that were previously handled by the MCU.

This lowers the load on the MCU and leads to reduced power consumption and improved performance in applications.

The KX132-1211 has a maximum frequency band of 4,200Hz and accelerationIt can detect degrees (g) in the range of ±2g to ±16g. The higher-end product, KX134-1211, can detect a maximum frequency band of 8,500Hz and acceleration (g) in the range of ±8g to ±64g.

While the operating temperature of existing products is up to 85℃, the new product provides normal operation even at 105℃. Therefore, it is suitable for machine health monitoring, such as motor vibration analysis, in industrial equipment.

The current consumption is as low as 0.67µA in low consumption mode, and it is equipped with a Wake Up function and a Back to Sleep function, so it supports sensing of battery-powered devices such as wearable devices.

Meanwhile, mass production of the two products began this September with a production capacity of 100,000 units per month.
