NXP Semiconductors
PN532/C1
Near Field Communication (NFC) controller
The PN532 supports the following host interfaces:
•  SPI
•  I
2
C
•  High Speed UART (HSU)
An embedded low-dropout voltage regulator allows the device to be connected directly to 
a battery. In addition, a power switch is included to supply power to a secure IC.
