KW01 design note for TPMS application

[#1]

      The MKW01Z device is highly-integrated, cost-effective, smart radio, sub-1 GHz wireless node solution composed of a transceiver supporting FSK, GFSK, MSK, or OOK modulations with a low-power ARM® Cortex M0+ CPU. The highly integrated RF transceiver operates over a wide frequency range including 315 MHz, 433 MHz, 470 MHz, 868 MHz, 915MHz, 928 MHz, and 955 MHz in the license-free Industrial, Scientific and Medical (ISM) frequency bands. This configuration allows users to minimize the use of external components.

     The MPXY8600 is a sensor for use in applications that monitor tire pressure and temperature. It contains the pressure and temperature sensors, an X-axis and a Z-axis accelerometer, a microcontroller, an LF receiver and an RF transmitter all within a single package.

       This setup offer customers to utilize Freescale MPXY8600/8700 as transmitter and MKW01 as receiver to form 315MHz, 433.92MHz TPMS transmitter and receiver  total solution.
