Infineon Technologies XENSIV™- SP49

The SP49 product family provides highly integrated devices which perform all functions for a wheel module of a Tire Pressure Monitoring System suited for high-volume applications. The devices measure pressure in the range from 100 kPa up to 920 kPa and acceleration between -600 g and 600 g as well as temperature and supply voltage. Furthermore, they feature an efficient power management and an integrated microcontroller. An integrated LF receiver and RF transmitter allows wireless communication. For wired data transfer, hardware master/slave I²C interface can be used. Wired interfaces such as UART, SP, PWM can be realized in software.
