Tire Pressure Monitoring System Offers Single- or Dual-Axis Accelerometers

The FXTH87 tire pressure monitoring system (TPMS) family from Freescale Semiconductor is a system-in-package solution that provides low power consumption with a high level of functional integration. It features a dual-axis accelerometer architecture, pressure and temperature sensor, integrated 8-bit microcontroller (MCU), RF transmitter, and a low frequency receiver. Weighing only 0.3 grams and enclosed in a 7 x 7 x 2.2 mm package, the TPMS enables form factors ideal for developers who need to reduce weight and overall costs. RF power consumption of 7 mA ldd extends battery life and single- and dual-axis accelerometer options improve accuracy and enable more precise tire localization implementation.
