[edit] Infineon Integrated Solution

  • SP35 Tire Pressure Sensor
  • Integrated device, mounted on a printed circuit board with a battery and antenna, enables tier-one suppliers to meet the requirements of the new regulations.
  • Integrates an MEMS pressure sensor, acceleration sensor and temperature sensor with an 8-bit controller and wireless communication module.
  • It eliminates the need for separate communication chips, thus reducing complexity and reportedly cutting costs by about 10 percent.

[edit] Freescale’s Single-Package Solution

  • Semiconductor MPXY8300
  • capacitive pressure sensor, an 8-bit microcontroller, two-axis accelerometer and radio frequency transmitter in one package. *battery life beyond NHTSA’s ten-year requirement.
