Weighing in at just 0.3g and measuring only 7 x 7 x 2.2mm, the FXTH87 tyre pressure monitoring system from Freescale is claimed to be 50% smaller than similar products on the market.
The TPMS system in package solution offers low power consumption and comes with a dual-axis accelerometer architecture, pressure and temperature sensor, integrated MCU, RF transmitter and low frequency receiver.
"We have a long history of innovation and success in pressure systems and in the automotive market, and we're leveraging that history to bring this tiny, integrated, low power system solution to our automotive customers," said Babak Taheri, vice president and general manager for Freescale's sensors solutions division.
The FXTH87 family is said to provide the industry's lowest RF power consumption at 7mA. Both the single and dual axis accelerometer options improve accuracy and facilitate more precise tyre localisation implementation and universal interoperability.
In addition, Freescale says the integrated MCU and dedicated firmware offer the largest customer flash memory at 8kbyte, increasing application flexibility and reducing time to market.
