Communication Interface Mechanism




Microcontroller is the master of the communication and
communicate through MLX90130 set of command
Registers of MLX90130 auto. set when protocol selected
MLX90130 is taking care of the protocol framing (SOF,
EOF, CRC …) and returns bytes information
Two interrupt signals available to wake-up the
MLX90130 & the external microcontroller
MCU
MLX90130
Select Protocol ISO 15693 , single subcarrier
Protocol selected , ready to communicate
Send protocol related data, CRC automatically
added (e.g. “022000” + CRC)
Return tag answer ,
e.g. “001234ABCD”, CRC correct)
Select another protocol
(e.g. ISO14443A, 7-bit mode)
Protocol selected , ready to communicate
Send protocol related data, CRC automatically
(e.g. “26”)
Return TAG answer
(e.g. “0400” , Parity is OK, CRC ignored)
Turn field OFF
Field is OFF

Power modes

4-different power modes available:
 Hibernate (typ. 10μA)
 Sleep (typ. 20μA)
 Tag Detector (typ. 45μA)
 Active (typ. 100mA in reader mode)

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
MLX90130 generates IRQ signal to wake-up the
external microcontroller as soon as TAG is detected
