NFC enabled car for access and start


Car access:
 The user is positioning the NFC
phone/card close to the door
handle, the car is interrogating the
NFC phone/card and if and open
the car if it matches
Start:
 When in the car, the user put the
NFC phone/card in a dedicated slot
and pressed the “start” button, the
engine is started if correct NFC
phone/card is recognized

Communication Interface Mechanism




Microcontroller is the master of the communication and
communicate through MLX90132 set of command
Registers of MLX90132 auto. set when protocol selected
MLX90132 is taking care of the protocol framing (SOF,
EOF, CRC …) and returns bytes information
Two interrupt signals available to wake-up the
MLX90132 & the external microcontroller

TAG detection state-machine



Short impulses of HF field to detect any variations of
amplitude
Number of HF pulses & waiting time fully
programmable depending on the application &
environment
MLX90132 generates IRQ signal to wake-up the
external microcontroller as soon as TAG is detected
