It’s natural to combine NFC controller with current wireless chip to cut cost and save space.
Back in Feb 2012, TI is the 1st company to announce NFC combo chip: “WiLink 8.0” chip that integrates NFC, Wi-Fi, GNSS Bluetooth and FM transmit/receive technologies”.
Soon after, Marvell also announced NFC combo chip WLAN/BT/NFC.
I’m sure that other semi-conductors, such as Broadcom and Qualcomm …, are working on NFC combo chips. It’s just a matter of time for them to release.
