NXP’s MC33596 access and remote control solution helps you streamline existing RF solutions or allows you to add the convenience of wireless control to your products. The MC33596’s context switching feature enables it to receive communications from either remote keyless entry (RKE) or tire pressure monitoring systems (TPMS). This allows optimization of the TPMS, RKE or passive entry receivers in the car body. In addition, the MC33596 can be used across a voltage range of 2.1–5.5V.
The MC33596 includes a programmable fractional phase-locked loop (PLL), a received signal strength indicator (RSSI) circuit and a periodic wake-up timer. The periodic wake-up timer activates the receiver, while a data manager checks the content of incoming messages and can switch between a TPMS and RKE frame without using the microcontroller.
