FXTH87E Tire Pressure Monitor Sensor (TPMS) Family

Overview

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

QFN 7 x 7 x 2.2 mm package enables visible solder joint for inspection
100–500 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, free-running counter, and periodic reset is 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)
