NFC-enabled LSI (CLF)

This is a photo of T6NE2XBG.

Toshiba has launched the "T6NE2XBG" NFC[1] controller LSI (CLF[2]) for secure mobile payments using proximity wireless communication.
The market for mobile payments, using smartphones and other mobile devices in transactions, is growing. The T6NE2XBG enables multiple concurrent connections with three different secure elements (SE[3]), allowing manufacturers to design NFC-enabled applications before the SE for the transaction system is determined.
Toshiba has shipped more than 400 million custom LSIs for proximity cards and mobile payment systems. The expertise in RF[4] technology that Toshiba has gained through this experience is integrated in the new product.


Concurrent connection up to three multiple SEs
A range of SEs are being deployed into applications to meet the different requirements of payment system operators. The new product enables multiple concurrent connections to a maximum of three different SEs, making it possible to design applications before the system SE is finalized. The product also supports thee different communication protocols to SEs.
Integrated circuit to adjust RF connectivity
Manufacturers need to adjust RF connectivity of NFC-enabled devices to receive necessary certification that payment system operators require. The product integrates an adjustment circuit and records each parameter into embedded EEPROM, which enables adjustment of each operating mode (card emulation, reader writer, and P2P[5]) and different RF modulation options (Type A, B and F).
