描述 Description

The FXTH87E is a highly integrated tire pressure sensor family and is providing the following features.
Small footprint in a 7mm x 7mm package
Low power consumption at 180 nA tvp (Stand-by current @ 3.0V, 25°C)
Large memory size at 16 kB
A field-proven dual-axis accelerometer architecture; the XZ axis offers motion detection and tire localization capabilities
