[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.
