Remote Keyless Entry

Remote Keyless Entry (RKE) is widely used in modern cars. Compared to discrete SAW-based solutions, PLL based solutions have clear advantages in time-to-market, logistics cost, quality and reliability.
Nowadays easiest key fob designs are possible based on Infineon’s highly integrated SmartLEWISTM MCU family, which combines the transmitter and the micro-controller on one single chip.
