2 GENERAL DESCRIPTION
The HITAG™ product line is well known and established in
the contactless identification market.
Due to the open marketing strategy of Philips
Semiconductors there are various manufacturers well
established for both the transponders / cards as well as the
Read/Write Devices. All of th em supporting HITAG 1 and
HITAG 2 transponder IC's. With the new HITAG S family,
this existing infrastr ucture is extended with th e next
generation of IC’s being substantially smaller in
mechanical size, lower in cost, offering more operation
distance and speed, but still being operated with the same
reader infrastructure and transponder manufacturing
equipment.
One Protocol - three memory options.
The protocol and command structure for HITAG S is based
on HITAG 1, including anticollision algorithm.
Three different memory sizes are offered and can be
operated using exac tly the same protocol.
HITAG S 32 32 Bit Unique Identifier Read Only
HITAG S 256 256 Bit Total Memory Read/Write
HITAG S 2048 2048 Bit Total Memory Read/Write
2.1 Target Markets
2.1.1 ANIMAL IDENTIFICATION
Basically, the animal id marke t can be divi ded into two
different areas:
a) Identification of pet animals
Some countries require that the your dog/cat is being
microchiped prior to immigration. But it is also of advantage
in case your pet is getting lost. The microchiped pet gets
easily identified with a handheld reader and thus can be
distinguished from stray animals.
The ISO standard 11784/85 is well established in this
markets and HITAG S 256 and HITAG S 2048 are
compliant to this standard, while offering additional
memory for storage of custo mised off line data, such as
phone number/address of the pets owne r.
b) Identification and Tracking of livestock like cattle,
pork and sheep
Being compatible with the ISO 11784/85 reader
infrastructure, HITAG S can be switched temporarily into
read/write mode, thus enabling additional features, like e.g.
off line data storage direc tly on the animals tag
This concept h as already been standardised within
ISO 14223/1.
2.1.2 LAUNDRY AUTOMATION
•Identify 200 pcs of garment with one Read/Write Device
•Long operation distance with typical small shaped
laundry button transponders
•Insensitive to harsh conditions like pressure, heat and
water.
2.1.3 BEER KEG AND GAS CYLINDER LOGISTIC
•Recognising a c omplete pallet of gas cylinders at one
time.
•Long writing distance.
•Voluntarily change between TTF Mode with user defined
data length and Read/Write Modes with out changing the
configuration on the transponder.
•Authenticity check at the beer pub s- betw een beer
bumper and supplied beer keg, provid es a safe
protection of the beer brand .
2.1.4 PIGEON RACE SPORTS
According to European pigeon race standards, offering the
additional shadow memory, that is required in some
European companie s.
2.1.5 SECURITY APPLICATIONS
Authenticity check for high level brands or for original
refilling e.g. toner for fax machines.
2.1.6 ACCESS CONTROL, COMPANY CARDS, AMUSEMENT
PARKS
The included encry pted authentication featur e is well
suited for applications like access control and vending
machines. In partic ula r the combined application with on e
company card opening the barrier for the car parking,
opening the access to the building and rooms with different
security levels, offering drinks and coffee from the vending
machines in the socialising area.

HITAG S HTS IC H32/HTS IC H56/HTS IC H48
4 BLOCKDIAGRAM
The HITAG S Transponder requires no external power supply. The contactless interface generates the power supply and
the system clock via the resonant circuitry by inductive coupling to the Read/Write Device (RWD). The interface a l so
demodulates data transmitted from the RWD to the HITAG S Transponder, and modula te s the magnetic field for data
transmission from the HITAG S Transponder to the RWD.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a capacity up to 2048 Bit and is organised in
64 Pages consisting of 4 Byte s ea ch (1 Page = 32 Bits) .

7.2 Energy Transmission
Passive transponders mus t some how be supplied with energy to be able to operate. In the HITAG System, this is
achieved by using the prin ciple of a loose coupled transformer:
The RWD antenn a generates a magnetic field. Some of the generated magnetic flux flows through the transponder
antenna and induces a voltage there. The voltage drives a current and the transponder will start operating. As this current
will be very small when the transponder is far away from the antenna, the HITAG S Transponder IC is designed for low
power consumption.
The principle of a loose coupled transformer enables also a bi-directional data transmission.

7.3 Data Transmission: Transponder → Read/Write Device
For data transmission from the HITAG S Transponder to the RWD, the implemented method is called 'load modulation'.
Here the HITAG S Transpon der continuously changes the loa d on the magnetic field, by in principle turning on/off a
resistor, according to the information to transmit. Alteration of the magnetic field is detected by the receiver of the RWD.
The modulation ratio of the RWD antenna voltage depends on the coupling factor of the antenna co nfiguration (RWD
antenna size, transponder antenna size, distance between the antennas,...).

7.3.1 CODING
Three different coding techniques for different States and Modes of the HITAG S Transponder IC are used (see also
Chapters 11 “Command Set” and 12 “Transponder Talks First (TTF) Mode”:
•AC: Anticollision Coding in Init State
•MC: Manchester Coding in Selected State and in Transponder Talks First State
•BC: Biphase Coding in Transponder Talks First State
A high level of the above coding signals means the physical state ‘modulator on’ (field loaded), a low level means
‘modulator off’ (field unlo aded).

10.1 General Description of States
Power Off
The powering magnetic field is switched off or the
HITAG S Transponder is out of field.
Ready
After start up phase, the HITAG S Transponder is ready to
receive the first command.
Init
The HITAG S Transponder enters this State after the first
UID REQUEST xx command. In this State the Response
Protocol Mode (see Chapter11 “Command Set”) may be
changed by further UID REQUEST xx commands. If there
are several HITAG S Transponders in the field of the RWD
antenna at the same time, the AC SEQUENCE can be
started to determine the UID of every HITAG S
Transponder.
Authenticate
The HITAG S Transponder enters this State after a valid
SELECT (UID) command wh en configured in
Authentication Mode. After an encrypted CHALLENGE
Authentication the HITAG S Transponder changes into the
Selected State.
Selected
The HITAG S Transponder enters this State after a valid
SELECT (UID) command when configured in Plain Mode
or a SELECT (UID) and CHALLENGE sequence when
configured in Authentication Mode. Only one HITAG S
Transponder in the field of the RWD antenna can be
Selected at the same time. In this State, Read and Write
operations are po ssible. Data Transmission is not
encrypted e ve n if c onfigured in Authentication Mode.
Quiet
The HITAG S Transpon der enters this State after a
SELECT_QUIET command in Init State or a QUIET
command in Selected State. In this State, the HITAG S
Transponder will not answer to any command. Switching
off the powering magnetic field or moving the HITAG S
Transponder out of field enters it into the Power Off State.
Transponder Talks First (TTF)
The HITAG S Transponder enters this State when
configured in TTF Mode if no UID REQUEST xx command
is received within the Mode switch window. Once entered
this State, the HITAG S Transponder continuously
transmits data with configurable data coding, data rate and
data length.

After the RWD transmits this command, all HITAG S Transponders located in the field of the RWD antenna respond with
a start of frame pattern followed by the corresponding 32 Bit UID. The complete response of the HITAG S Transponder
is transmitted in Anticollision Coding (AC, see Section 7.3.1 “C oding”).

11.3 AC SEQUENCE
If more than one HITAG S Transpo nder is in the field of the antenna a special designed RWD detects the first collision
at the Bit position N = k of the UID response. As a result the RWD starts an Anticollision Sequence (AC SEQUENCE).
This command consists of a 5 Bit number (k4 to k0) describing the physical Bit position k where the collision occurred
followed by (k - 1) Bits of the detected UID and a Bit (one or zero) at the collision position. An 8 Bit CRC (cyclic
redundancy ch ec k) of this sequence is also sent to the transponders.
After transmitting this command, all HITAG S Tran sponders which first k Bits of the own UID match with the k received
UID Bits, answer with the SOF and the rest of their own UID.
If a collision occurs again the described cycle has to be repeated until one valid UID of the transponders in the field is
determined.
The complete response of the HITAG S Transponder is transmitted in Anticollision Coding (AC).

During the AC SEQUENCE commands the HITAG S Transponder stay s in Init State. Even those HITAG S

11.4 SELECT (UID)
The SELECT (UID) command consists of 5 Zero-Bits followed by the determined 32 Bit UID and an 8 Bit Cyclic
Redundancy Check (CRC). The selected transponder then responds with a start of frame pattern (SOF) followed by the
content of the Configuration Page and depending on the Response Protocol Mode with an 8 Bit CRC.
The complete response of the HITAG S Transponder is transmitted in Manchester Coding (MC).
In Plain Mode the MSByte of Page 1 is a Reserved Byte, in Authentication Mode this Byte contains the password high

in Authentication Mode (Bit AUT = 1) and starts the encrypted Challenge sequence.
The Read/Write Dev i ce sends a 32 Bit Random Number (R ND ) and a 32 Bit secret data stre am to th e tra nsponder. In
order to perform the secret data stream, a security co-processor is required on the read/write Device. For more
information please contact us at - info.bli@philips.com.
If the received secret data stream corresponds with the secret data stream calculated by the HITAG S Transponder, a
32 Bit Secret Response (secret data stream encrypting the configuration byte CON 2, password high byte PWDH 0 and
password low Bytes PWDL 0 and PWDL 1) is transmitted after the SOF.
The response of the HITAG S Transponder is transmitted in Manchester Coding (MC).

12 TRANSPONDER TALKS FIRST (TTF) MODE
This special mode of the HITAG S Transponder enable s data transmiss ion to a Read/W rite Device without sendin g any
command. The TTF Mode can be enabled/disabled and configured by setting the corresponding Bits of the Configuration
byte CON 1 (see Chapter 8 “Configuration”).
A HITAG S Transponder configured in TTF Mode can be switched temporarily into Reader Talks First (RTF) Mode by
sending a UID REQUEST xx command within a defined window after turning on the powering field. The HITAG S
Transponder will leave this temporarily RTF Mode after switching off the powering field or moving it out of the RWD
antenna field.
If the HITAG S Transponder is configured in TTF Mode and no Mode switch command is sent by the RWD within the
defined switch window it enters the TTF State. Depending on the configuration, the HITAG S Transponder transmits the
data with different coding, data rate an d data length. It is recommended to use some of the data bits as a well defined
start sequence.
12.1 32 Bit TTF Mode
Configuration:
In this Mode, the HITAG S Trans ponder continuously transmits the data content of Page 4.
The data rate and the data coding can be chosen independently by configuration Bits TTFC, TTFDR 0 and TTFDR 1.
12.2 64 Bit TTF Mode
Configuration:
In this Mode, the HITAG S Trans ponder continuously transmits the data content of Page 4 and Page 5.
The data rate and the data coding can be chosen independently by configuration Bits TTFC, TTFDR 0 and TTFDR 1.
Note: This Mode may be used for Pigeon race standards.

13 DATA INTEGRITY / CALCULATION OF CRC
The following explanations show the features of the
HITAG S protocol to protect read and write access to
transponders from undetected errors.
13.1 Data Transmission: Re ad/Write Device to
HITAG S Transponder
Every data stream transmitted by the Read/Write Device to
the HITAG S Transponder includes an 8 Bit Cyclic
Redundancy Check (CRC 8).
The data stream is fir st c hecked for data errors by the
HITAG S Transponder and then executed.
The generator polynomial for the CRC 8 is:
u8 + u4 + u3 + u2 + 1 = 0x1D
The CRC pre set value is: 0x FF
13.2 Data Transmission: HITAG S Transponder to
Read/Write Device
13.2.1 STANDARD RESPONSE PROTOCOL MODE
The HITAG S Transponder response does not include any
check sum because of flexibility reasons. To get the data
integrity required by the ap plication, check sums have to
be calculated by the use r software and stored together
with the information in the transponder memory. This
seems uncomfortable, because the check sums use a little
part of the available memory sp ace in the transponder.
The advantage of this solution is the flexibility to choose
large checksums for applications requiring high data
integrity and smaller check sums for applications requiring
short access times which means short protocols.
13.2.2 ADVANCED/FAST ADVANCED RESPONSE
PROTOCOL MODE
In Advanced – and Fast Advanced Response Protoc ol
Mode the response on a SELECT (UI D), CHALLENGE,
READ PAGE, READ BLOCK command, includes a CRC 8
check sum.
The generator polynomial for the CRC 8 is:
u8 + u4 + u3 + u2 + 1 = 0x1D
The CRC pre set value is: 0x FF
