The FXTH87 is a highly integrated tire pressure sensor family and features:
- Very small footprint in a 7 mm x 7 mm package
- Very low power consumption
- Very large memory size at 8 kB
- 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
- 100–450 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 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)
