FXTH87: FXTH87 Tire Pressure Monitor Sensor Family

Overview

The FXTH87 is a highly integrated tire pressure sensor family and features:

The smallest footprint in a 7mm x 7mm package
Lowest power consumption
Largest memory size at 8 kB
Unique dual-axis accelerometer architecture; the XZ axis offers motion detection and tire localization capabilities

Features

QFN 7 x 7 x 2.2 mm package enables visible solder joint for inspection
100–450 kPa and 100–900 kPa pressure ranges
Z-axis or dual XZ-axis accelerometers
Accelerometer standard or precision tolerances available
Low-power wake-up timer and periodic reset driven by LFO
Dedicated state machines for reduced power consumption
8-bit MCU/S08 core with SIM, interrupt and debug/monitor
512 Bytes RAM / 16 k Flash (8 k for NXP^® library, 8 k for applications)
Internal 315/434 MHz RF transmitter
Internal 125 kHz LF receiver
Six multipurpose GPIO pins (including two A/D inputs)
