The F8216 are the new NFC forum compliant Type 2 tag products developed by FEIJU Microelectronics for applications in electronics (i.e. connection handover, Bluetooth simple pairing, Wi-Fi Protected set-up, device authentication, gaming and others) .
On top of offering a large range of User memory (888bytes), the FAST_READ command and a configurable password protection.
The F8216 product family is designed to fully comply to NFC Forum Type 2 Tag and ISO/IEC88843 Type A specifications.
1.1 Contactless energy and data transfer
Communication to F8216 can be established only when the IC is connected to an antenna. Form and specification of the antenna is out of scope of this document.
When F8216 is positioned in the RF field, the high speed RF communication interface allows the transmission of the data with a baud rate of 106 kbit/s.
1.2 Simple deployment and user convenience
F8216 offers specific features designed to improve integration and user convenience:
• The fast read capability allows to scan the complete NDEF message with only one FAST_READ command, thus reducing the communication time overhead
• The improved RF performance allows for more flexibility in the choice of shape, dimension and materials
• The field detect functionality is based on an open-drain implementation that requires only one pull up resistor
1.3 Security
• Manufacturer programmed 7-byte UID for each device
• Capability container with one time programmable bits
• Field programmable read-only locking function per page up to 0Fh page (per 2 pages for the extended memory section)
• ECC based originality signature
• 32-bit password protection to prevent unauthorized memory operations
1.4 NFC Forum Tag 2 Type compliance
F8216 IC provides full compliance to the NFC Forum Tag 2 Type technical specification and enables NDEF data structure configurations.
1.5 Anticollision
An intelligent anticollision function allows to operate more than one tag in the field simultaneously. The anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a selected tag is performed correctly without interference from another tag in the field.

2. Product Overview
2.1 Introduction
F8216 is NFC Forum Type 2 Tag compliant IC according to ISO14443 Type A development by Shanghai Feiju Microelectronics Co., Ltd. The F8216 chip consists of the 168 bytes of the total memory organized in 228 user memory EEPROM. From that amount, 888 bytes (222 pages) are available for the user defined data.
Along with the memory, F8216 contains the RF-Interface and the Digital Control Unit. Energy and data are transferred via an antenna, which consists of a coil with a few turns directly connected to the RF1 and RF2 of the F8216. No further external components are necessary.
