Functional description 8.1 Block description NTAG21x ICs consist of a 80 (NTAG210) or 164 bytes (NTAG212) EEPROM, RF interface and Digital Control Unit (DCU). Energy and data are transferred via an antenna consisting of a coil with a few turns which is directly connected to NTAG21x. No further external components are necessary. Refer to Ref. 4 for details on antenna design. • RF interface: – modulator/demodulator – rectifier – clock regenerator – Power-On Reset (POR) – voltage regulator • Anticollision: multiple cards may be selected and managed in sequence • Command interpreter: processes memory access commands supported by the NTAG21x • EEPROM interface • NTAG210 EEPROM: 80 bytes, organized in 20 pages of 4 byte per page. – 26 bytes reserved for manufacturer and configuration data – 16 bits used for the read-only locking mechanism – 4 bytes available as capability container – 48 bytes user programmable read/write memory • NTAG212 EEPROM: 164 bytes, organized in 41 pages of 4 byte per page. – 26 bytes reserved for manufacturer and configuration data – 31 bits used for the read-only locking mechanism – 4 bytes available as capability container – 128 bytes user programmable read/write memory NTAG210_212 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

All rights reserved. 5 of 46 NTAG210/212 NXP Semiconductors NFC Forum Type 2 Tag compliant IC with 48/128 bytes user memory 8.2 RF interface The RF-interface is based on the ISO/IEC 14443 Type A standard. During operation, the NFC device generates an RF field. The RF field must always be present (with short pauses for dat communication) as it is used for both communication and as power supply for the tag. For both directions of data communication, there is one start bit at the beginning of each frame. Each byte is transmitted with an odd parity bit at the end. The LSB of the byte with the lowest address of the selected block is transmitted first. The maximum length of a NFC device to tag frame is 163 bits (16 data bytes + 2 CRC bytes = 16×9 + 2×9 + 1 start bit). The maximum length of a fixed size tag to NFC device frame is 307 bits (32 data bytes + 2 CRC bytes = 32 9 + 2 9 + 1 start bit). The FAST_READ command has a variable frame length depending on the start and end address parameters. The maximum frame length supported by the NFC device needs to be taken into account when issuing this command. For a multi-byte parameter, the least significant byte is always transmitted first. As an example, when reading from the memory using the READ command, byte 0 from the addressed block is transmitted first, followed by bytes 1 to byte 3 out of this block. The same sequence continues for the next block and all subsequent blocks. 8.3 Data integrity Following mechanisms are implemented in the contactless communication link between NFC device and NTAG to ensure very reliable data transmission: • • • • • NTAG210_212 Product data sheet COMPANY PUBLIC 16 bits CRC per block parity bits for each byte bit count checking bit coding to distinguish between “1”, “0” and “no information” channel monitoring (protocol sequence and bit stream analysis) All information provided in this document is subject to legal disclaimers.

The command response is depending on the state of the IC and for memory operations also on the access conditions valid for the corresponding page. POR HALT IDLE REQA WUPA WUPA READY 1 READ from page 0 HLTA HLTA identification and selection procedure ANTICOLLISION SELECT cascade level 1 READY 2 ANTICOLLISION READ from page 0 SELECT cascade level 2 ACTIVE PWD_AUTH AUTHENTICATED memory operations READ (16 Byte) FAST_READ WRITE, COMPATIBILITY_WRITE (4 Byte) GET _ VERSION READ_SIG aaa-006980 Remark: In all states, the command interpreter returns to the idle state on receipt of an unexpected command. If the IC was previously in the HALT state, it returns to that state. Fig 3.

All rights reserved. 7 of 46 NTAG210/212 NXP Semiconductors NFC Forum Type 2 Tag compliant IC with 48/128 bytes user memory 8.4.1 IDLE state After a power-on reset (POR), NTAG21x switches to the IDLE state. It only exits this state when a REQA or a WUPA command is received from the NFC device. Any other data received while in this state is interpreted as an error and NTAG21x remains in the IDLE state. After a correctly executed HLTA command i.e. out of the ACTIVE or AUTHENTICATED state, the default waiting state changes from the IDLE state to the HALT state. This state can then be exited with a WUPA command only. 8.4.2 READY1 state In this state, the NFC device resolves the first part of the UID (3 bytes) using the ANTICOLLISION or SELECT commands in cascade level 1. This state is correctly exited after execution of either of the following commands: • SELECT command from cascade level 1: the NFC device switches NTAG21x into READY2 state where the second part of the UID is resolved. • READ command (from address 0): all anticollision mechanisms are bypassed and the NTAG21x switches directly to the ACTIVE state. Remark: If more than one NTAG is in the NFC device field, a READ command from address 0 selects all NTAG21x devices. In this case, a collision occurs due to different serial numbers. Any other data received in the READY1 state is interpreted as an error and depending on its previous state NTAG21x returns to the IDLE or HALT state. 8.4.3 READY2 state In this state, NTAG21x supports the NFC device in resolving the second part of its UID (4 bytes) with the cascade level 2 ANTICOLLISION command. This state is usually exited using the cascade level 2 SELECT command. Alternatively, READY2 state can be skipped using a READ command (from address 0) as described for the READY1 state. Remark: The response of NTAG21x to the cascade level 2 SELECT command is the Select AcKnowledge (SAK) byte. In accordance with ISO/IEC 14443, this byte indicates if the anticollision cascade procedure has finished. NTAG21x is now uniquely selected and only this device will communicate with the NFC device even when other contactless devices are present in the NFC device field. If more than one NTAG21x is in the NFC device field, a READ command from address 0 selects all NTAG21x devices. In this case, a collision occurs due to the different serial numbers. Any other data received when the device is in this state is interpreted as an error. Depending on its previous state the NTAG21x returns to either the IDLE state or HALT state.

All rights reserved. 8 of 46 NTAG210/212 NXP Semiconductors NFC Forum Type 2 Tag compliant IC with 48/128 bytes user memory 8.4.4 ACTIVE state All memory operations and other functions like the originality check are operated in the ACTIVE state. The ACTIVE state is exited with the HLTA command and upon reception NTAG21x transits to the HALT state. Any other data received when the device is in this state is interpreted as an error. Depending on its previous state NTAG21x returns to either the IDLE state or HALT state. NTAG21x transits to the AUTHENTICATED state after successful password verification using the PWD_AUTH command. 8.4.5 AUTHENTICATED state In this state, all operations on memory pages, which are configured as password verification protected, can be accessed. The AUTHENTICATED state is exited with the HLTA command and upon reception NTAG21x transits to the HALT state. Any other data received when the device is in this state is interpreted as an error. Depending on its previous state NTAG21x returns to either the IDLE state or HALT state. 8.4.6 HALT state HALT and IDLE states constitute the two wait states implemented in NTAG21x. An already processed NTAG21x can be set into the HALT state using the HLTA command. In the anticollision phase, this state helps the NFC device to distinguish between processed tags and tags yet to be selected. NTAG21x can only exit this state on execution of the WUPA command. Any other data received when the device is in this state is interpreted as an error and NTAG21x state remains unchanged.

SN0 holds the Manufacturer ID for NXP Semiconductors (04h) in accordance with ISO/IEC 14443-3. 8.5.2 Static lock bytes (NTAG21x) The bits of byte 2 and byte 3 of page 02h represent the field programmable read-only locking mechanism. Each page from 03h (CC) to 0Fh can be individually locked by setting the corresponding locking bit Lx to logic 1 to prevent further write access. After locking, the corresponding page becomes read-only memory. The three least significant bits of lock byte 0 are the block-locking bits. Bit 2 deals with pages 0Ah to 0Fh, bit 1 deals with pages 04h to 09h and bit 0 deals with page 03h (CC). Once the block-locking bits are set, the locking configuration for the corresponding memory area is frozen.

If write protection is enabled, each write attempt leads to a NAK response. 8.6 UID ASCII mirror function NTAG21x features a UID ASCII mirror function. This function enables NTAG21x to virtually mirror the 7 byte UID in ASCII code into the physical memory of the IC. The length of the UID ASCII mirror requires 14 bytes to mirror the UID in ASCII code. On the READ or FAST READ command to the involved user memory pages, NTAG21x will respond with the virtual memory content of the UID in ASCII code. The position within the user memory where the mirroring of the UID shall start is defined by the MIRROR_PAGE and MIRROR_BYTE values. The MIRROR_PAGE value defines the page where the UID ASCII mirror shall start and the MIRROR_BYTE value defines the starting byte within the defined page. The UID ASCII mirror function is enabled with a MIRROR_PAGE value >03h. Remark: Please note that the 14 bytes of the UID ASCII mirror shall not exceed the boundary of the user memory. Therefor it is required to use only valid values for MIRROR_BYTE and MIRROR_PAGE to ensure a proper functionality. Table 10.

The 32-bit secret password (PWD) and the 16-bit password acknowledge (PACK) response are typically programmed into the configuration pages at the tag personalization stage. The AUTHLIM parameter specified in Section 8.5.7 can be used to limit the negative verification attempts. In the initial state of NTAG21x, password protection is disabled by a AUTH0 value of FFh. PWD and PACK are freely writable in this state. Access to the configuration pages and any part of the user memory can be restricted by setting AUTH0 to a page address within the available memory space. This page address is the first one protected. Remark: The password protection method provided in NTAG21x has to be intended as an easy and convenient way to prevent unauthorized memory accesses. If a higher level of protection is required, cryptographic methods can be implemented at application layer to increase overall system security. 8.7.1 Programming of PWD and PACK The 32-bit PWD and the 16-bit PACK need to be programmed into the configuration pages, see Section 8.5.7. The password as well as the password acknowledge are written LSByte first. This byte order is the same as the byte order used during the PWD_AUTH command and its response. The PWD and PACK bytes can never be read out of the memory. Instead of transmitting the real value on any valid READ or FAST_READ command, only 00h bytes are replied. If the password verification does not protect the configuration pages, PWD and PACK can be written with normal WRITE and COMPATIBILITY_WRITE commands. If the configuration pages are protected by the password configuration, PWD and PACK can be written after a successful PWD_AUTH command. The PWD and PACK are writable even if the CFGLCK bit is set to 1b. Therefore it is strongly recommended to set AUTH0 to the page where the PWD is located after the password has been written. This page is 12h for NTAG210 and 27h for NTAG212. Remark: To improve the overall system security, it is advisable to diversify the password and the password acknowledge using a die individual parameter of the iC, that is the 7-byte UID available on NTAG21x.

All rights reserved. 19 of 46 NTAG210/212 NXP Semiconductors NFC Forum Type 2 Tag compliant IC with 48/128 bytes user memory 8.7.2 Limiting negative verification attempts To prevent brute-force attacks on the password, the maximum allowed number of negative password verification attempts can be set using AUTHLIM. This mechanism is disabled by setting AUTHLIM to a value of 000b, which is also the initial state of NTAG21x. If AUTHLIM is not equal to 000b, each negative authentication verification is internally counted. As soon as this internal counter reaches the number specified in AUTHLIM, any further negative password verification leads to a permanent locking of the protected part of the memory for the specified access modes. Specifically, whether the provided password is correct or not, each subsequent PWD_AUTH fails. Any successful password verification, before reaching the limit of negative password verification attempts, resets the internal counter to zero. 8.7.3 Protection of special memory segments The configuration pages can be protected by the password authentication as well. The protection level is defined with the PROT bit. The protection is enabled by setting the AUTH0 byte to a value that is within the addressable memory space. 8.8 Originality signature NTAG21x features a cryptographically supported originality check. With this feature, it is possible to verify with a certain confidence that the tag is using an IC manufactured by NXP Semiconductors. This check can be performed on personalized tags as well. NTAG21x digital signature is based on standard Elliptic Curve Cryptography (curve name secp128r1), according to the ECDSA algorithm. The use of a standard algorithm and curve ensures easy software integration of the originality check procedure in NFC devices without specific hardware requirements. Each NTAG21x UID is signed with a NXP private key and the resulting 32-byte signature is stored in a hidden part of the NTAG21x memory during IC production. This signature can be retrieved using the READ_SIG command and can be verified in the NFC device by using the corresponding ECC public key provided by NXP. In case the NXP public key is stored in the NFC device, the complete signature verification procedure can be performed offline. To verify the signature (for example with the use of the public domain crypto library OpenSSL) the tool domain parameters shall be set to secp128r1, defined within the standards for elliptic curve cryptography SEC (Ref. 7). Details on how to check the signature value are provided in following application note (Ref. 5). It is foreseen to offer an online and offline way to verify originality of NTAG21x.

[2] This command is new in NTAG21x compared to NTAG203. 9.2 Timings The command and response timings shown in this document are not to scale and values are rounded to 1 s. All given command and response times refer to the data frames including start of communication and end of communication. They do not include the encoding (like the Miller pulses). A NFC device data frame contains the start of communication (1 “start bit”) and the end of communication (one logic 0 + 1 bit length of unmodulated carrier). A NFC tag data frame contains the start of communication (1 “start bit”) and the end of communication (1 bit length of no subcarrier). The minimum command response time is specified according to Ref. 1 as an integer n which specifies the NFC device to NFC tag frame delay time. The frame delay time from NFC tag to NFC device is at least 87 s. The maximum command response time is specified as a time-out value. Depending on the command, the TACK value specified for command responses defines the NFC device to NFC tag frame delay time. It does it for either the 4-bit ACK value specified in Section 9.3 or for a data frame.

In the initial state of NTAG21x, the following memory pages are valid Addr parameters to the COMPATIBILITY_WRITE command. • page address 02h to 13h for NTAG210 • page address 02h to 28h for NTAG212 Addressing a memory page beyond the limits above results in a NAK response from NTAG21x. Pages which are locked against writing cannot be reprogrammed using any write command. The locking mechanisms include static and dynamic lock bits as well as the locking of the configuration pages. The following conditions apply if part of the memory is password protected for write access: • if NTAG21x is in the ACTIVE state – writing to a page which address is equal or higher than AUTH0 results in a NAK response • if NTAG21x is in the AUTHENTICATED state – the COMPATIBILITY_WRITE command behaves the same as on a NTAG21x without access protection NTAG21x features tearing protected write operations to specific memory content. The following pages are protected against tearing events during a COMPATIBILITY_WRITE operation: • page 2 containing static lock bits • page 3 containing CC bits • page 36 containing the additional dynamic lock bits for the NTAG212 NTAG210_212 Product data sheet COMPANY PUBLIC All information provided in this document is subject to legal disclaimers.

The AUTH0 configuration byte defines the protected area. It specifies the first page that the password mechanism protects. The level of protection can be configured using the PROT bit either for write protection or read/write protection. The PWD_AUTH command takes the password as parameter and, if successful, returns the password authentication acknowledge, PACK. By setting the AUTHLIM configuration bits to a value larger than 000b, the number of unsuccessful password verifications can be limited. Each unsuccessful authentication is then counted in a counter featuring anti-tearing support. After reaching the limit of unsuccessful attempts, the memory access specified in PROT, is no longer possible. The PWD_AUTH command is shown in Figure 17 and Table 28. Table 29 shows the required timing. NFC device Cmd Pwd CRC PACK NTAG ,,ACK'' TACK 623 µs 274 µs NAK NTAG ,,NAK'' TNAK 57 µs TTimeOut Time out aaa-006993 Fig 17. PWD_AUTH command Table 28.
