Summary of Freescale introduces world’s smallest integrated tire pressure monitoring system
Freescale introduced the FXTH87 family, the smallest integrated TPMS solution at 0.3 grams and 50% smaller than competitors. The system-in-package combines low power consumption with high integration: dual-axis accelerometer, pressure and temperature sensors, integrated MCU, RF transmitter, and low-frequency receiver. It aims to reduce BOM costs and support global TPMS mandates that improve safety, fuel economy, and emissions.
Parts used in the FXTH87 tire pressure monitoring system (TPMS):
- Dual-axis accelerometer
- Pressure sensor
- Temperature sensor
- Integrated microcontroller unit (MCU)
- RF transmitter
- Low-frequency receiver
- System-in-package housing (0.3 gram integrated package)
Freescale Semiconductor today introduced the FXTH87 tire pressure monitoring system (TPMS) family, which is the smallest integrated package TPMS solution available at an extremely light weight of 0.3 grams. The FXTH87 family is 50 percent smaller than competing products, helping designers reduce overall bill of materials costs. Freescale’s newest TPMS system-in-package solution provides low power consumption combined with the highest level of functional integration in one package, featuring a dual-axis accelerometer architecture, pressure and temperature sensor, integrated MCU, RF transmitter and low frequency receiver.
The National Highway Traffic Safety Administration estimates that 23,000 accidents and 535 vehicle fatalities occur each year involving flat tires or blowouts, which TPMS systems help prevent by ensuring proper tire inflation monitoring. In addition, properly inflated tires improve fuel economy and reduce emissions, resulting in many regions worldwide, including the United States, European Union, China, Japan and Taiwan, to begin requiring TPMS in new vehicles. According to IHS iSuppli, TPMS will represent more than 25 percent of the total pressure measurement market for automotive sensors by 2015.
