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
Feature
- 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)
