SYSTEM OVERVIEW
1.2
1.1
Key Terms
The HCS410/WM is an IFF transponder for verification
of a token. In IFF mode the HCS410/WM is ideally
suited for authentication of a key before disarming a
vehicle immobilizer. Once the key has been inserted in
the car’s ignition the decoder would inductively poll the
key, validating it before disarming the immobilizer.
• Anticollision – Allows multiple transponders to be
in the magnetic field simultaneously and be verified individually.
• Encoder Key – A unique 64-bit key generated and
programmed into the encoder during the manufacturing process. The encoder keycontrols the
encryption algorithm and is stored in EEPROM on
the transponder device.
• IFF – Identify friend or foe is a means of validating
a token. A decoder sends a random challenge to
the token and checks that the response of the
token is a valid response.
• KEELOQ Encryption Algorithm – The high security
level of the HCS410/WM is based on the patented
KEELOQ technology. A block cipher encryption
algorithm based on a block length of 32 bits and a
key length of 64 bits is used. The algorithm
obscures the information in such a way that even
if the unencrypted/challenge information differs by
only one bit from the information in the previous
challenge, the next coded response will be totally
different. Statistically, if only one bit in the 32-bit
string of information changes, approximately
50 percent of the coded transmission will change.
• Learn – The HCS product family facilitates several learning strategies to be implemented on the
decoder.
• Manufacturer’s Code – A 64-bit word, unique to
each manufacturer, used to produce a unique
encoder key in each transmitter (encoder).
• Transport Code – A 32-bit transport code needs to
be given before the HCS410/WM can be inductively programmed. This prevents accidental
programming of the HCS410.
FIGURE 1-1:
KEELOQ IFF
IFF validation of the token involves a random challenge
being sent by a decoder to a token. The token then
generates a response to the challenge and sends this
response to the decoder (Figure 1-1). The decoder calculates an expected response using the same challenge. The expected response is compared to the
response received from the token. If the responses
match, the token is identified as a valid token and the
decoder can take appropriate action.
The HCS410/WM can do either 16 or 32-bit IFF. The
HCS410/WM has two encryption algorithms that can
be used to generate a response to a challenge. In addition there are up to two encoder keys that can be used
by the HCS410/WM. Typically each HCS410/WM will
be programmed with a unique encoder key(s).
In IFF mode, the HCS410/WM will wait for a command
from the base station and respond to the command.
The command can either request a read/write from
user EEPROM or an IFF challenge response. A given
16 or 32-bit challenge will produce a unique 16/32-bit
response, based on the IFF key and IFF algorithm
used.

DEVICE DESCRIPTION
3.0
Figure 2-1 shows the internal components of the
HCS410/WM. The resonant LC circuit has 2 functions:
• Inductive antenna for communications between
the HCS410 and the base station
• Power source to charge the pool capacitor. The
pool capacitor functions as a battery when the
HCS410/WM is used.

IFF Mode Activation
The HCS410/WM will enter IFF mode if the capacitor/
inductor resonant circuit generates a voltage large
enough so that the pool capacitor can power the
device. After the verified application of power and
elapse of the reset period, the device will start responding by pulsing the field with ACK pulses as shown in
Figure 3-3. This action will continue until the pulse train
is terminated by receiving a start signal of duration 2TE,
on the LC inputs before the next expected ACK pulse.
The device now enters the IFF mode and expects to
receive an ‘Opcode’ and a 0/16/32-bit Data-stream to
react on. The data rate (TE) is determined by the Transponder Baud Select (IFFB) configuration option.

The user can perform an IFF validation, write to the
user EEPROM and read from the user EEPROM. Each
operation consists of the decoder sending an opcode
and data while the HCS410/WM gives a response.
There are two IFF modes: IFF1 and IFF2. IFF1 allows
only one key IFF, while IFF2 allows two keys to be
used.

HCS410/WM Responses
The responses from the HCS410/WM are in PPM format. See Figure 3-3 for additional information. Every
response from the HCS410 is preceded by a “2 bit preamble” of 012, and then 16/32 bits of data.
3.4
IFF Response
IFF Write
The decoder can write to USER[0:3], SER[0:1], and the
configuration word in the EEPROM.
TABLE 3-1:
Command
When writing to the serial number or configuration
word, the user must send the transport code before the
write will begin.
Note:
The 16/32-bit response to a 16/32-bit challenge, is
transmitted once, after which the device is ready to
accept another command. The same applies to the
result of a Read command. The opcode written to the
device specifies the challenge length and algorithm
used. The response always starts with a leading preamble of 012 followed by the 16/32 bits of data.
3.5
After the HCS410/WM has written the word into the
EEPROM, it will give two acknowledge pulses (TE wide
and TE apart) on the LC pins.
3.6
If the configuration word is written, the
device must be reset to allow the new configuration settings to come into effect.
IFF Read
The decoder can read USER[0:3], SER[0:1], and the
configuration word in the EEPROM. After the data has
been read, the device is ready to receive a command
again.
Each read command is followed by a 16-bit data
response. The response always starts with a leading
preamble of 012 and then the 16-bits of data.

IFF Special Features
3.7.1
ANTI-COLLISION (ACOLI)
When the ACOLI bit is set in the configuration word,
anti-collision mode is entered. The HCS410/WM will
start sending ACK pulses when it enters a magnetic
field. The ACK pulses stop as soon as the HCS410/
WM detects a start bit from the decoder. A ‘select
encoder’ opcode (00000) is then sent out by the
decoder, followed by a 32-bit serial number. If the serial
number matches the HCS410/WM’s serial number, the
HCS410/WM will acknowledge with the acknowledge
sequence as shown in Figure 3-4. The HCS410/WM
can then be addressed as normal. If the serial number
does not match, the IFF encoder will stop transmitting
ACK pulses until it is either removed from the field or
the correct serial number is given.

3.7.2
INTELLIGENT DAMPING
If the IDAMP bit is set to 0, the HCS410/WM will clamp
the LC pins for 5 µs every 1/4 TE, whenever the
HCS410/WM is expecting data from the decoder. The
intelligent damping pulses start 64 TE after the
acknowledge pulses have been sent and continue for
64 TE. If the HSC410 detects data from the base station
while sending out damp pulses, the damp pulses will
continue to be sent. The damping will help the LC circuit resonance decay faster when the field is removed.
This can make high to low data field decay sharper.

EEPROM ORGANIZATION AND
CONFIGURATION
The HCS410/WM has nonvolatile EEPROM memory
which is used to store user programmable options. This
information includes encoder keys, serial number, and
up to 64-bits of user information.
4.1
IFF Programming
After the EEPROM is erased, the configuration word is
reloaded. This results in oscillator tuning bits of 0000
being used during programming. When using IFF programming, the user should read the configuration word
and store the oscillator bits in the memory map to be
programmed. A program command should be sent and
the next set of ACK pulses transmitted by the HCS410/
WM should be used to determine the TE. A second program command can then be sent, and the device programmed using the TE just calibrated.
Encoder Key 1 and 2
In IFF operation, the HCS410/WM uses encoder key1
or key2 to generate the response to a challenge
received. The key or keys are created and programmed at the time of production using a key generation algorithm. Inputs to the key generation algorithm
are the serial number and a secret manufacturer’s
code. While a number of key generation algorithms are
supplied by Microchip, a user may elect to create their
own method of key generation. This may be done providing that the decoder is programmed with the same
means of creating the key for decryption purposes.
4.3
Transport Code
The least significant 32-bits of key2 are used as the
transport code. The transport code is used to write-protect the serial number, configuration word and prevent
accidental programming of the HCS410/WM.
4.4
Serial Number
There are 32 bits allocated for the serial number. The
serial number is meant to be unique for every transmitter. The serial number can be programmed with a write
command.
4.5
User Data
The 64-bit user EEPROM can be reprogrammed and
read at any time using the IFF interface.
 2001 Microchip Technology Inc.
Configuration Data
The configuration data is used to select various
encoder options. Further explanations of each of the
bits are described in the following sections.
TABLE 4-1:
Symbol
IDAMP
Upon receiving a programming opcode and the transport code, the EEPROM is erased. Thereafter, the first
16 bits of data can be written. After indicating that a
write command has been successfully completed the
device is ready to receive the next 16 bits. After a complete memory map was received, it will be transmitted
in PPM format on the LC pins as 16-bit words.

INTEGRATING THE
HCS410/WM INTO A SYSTEM
Use of the HCS410/WM in a system requires a compatible decoder. This decoder is typically a microcontroller
with compatible firmware. Firmware routines that
accept transmissions from the HCS410/WM, decrypt
the code hopping portion of the data stream and perform IFF functions are available. These routines provide system designers the means to develop their own
decoding system.
FIGURE 5-1:
5.1
The serial number for each transmitter is programmed
by the manufacturer at the time of production. The
generation of the encoder key is done using a key generation algorithm (Figure 5-1). Typically, inputs to the
key generation algorithm are the serial number of the
transmitter or seed value, and a 64-bit manufacturer’s
code. The manufacturer’s code is chosen by the system manufacturer and must be carefully controlled. The
manufacturer’s code is a pivotal part of the overall
system security.

Receiver Learning an HCS410/WM
In order for a transmitter to be used with a decoder, the
transmitter must first be ‘learned’. Several learning
strategies can be followed in the decoder implementation. When a transmitter is learned by a decoder, it is
suggested that the decoder stores the serial number in
EEPROM. The decoder must keep track of these
values for every transmitter that is learned.
The maximum number of transmitters that can be
learned is a function of how much EEPROM memory
storage is available. The decoder must also store the
manufacturer’s code in order to learn an HCS410/WM,
since this value will not change in a typical system, it is
usually stored as part of the microcontroller ROM code.
Storing the manufacturer’s code as part of the ROM
code is also better for security reasons.

IFF Decoder Operation
In a typical IFF decoder, the key generation on the
decoder side is done by reading the serial number from
a token and combining that with the manufacturer’s
code to recreate the encoder key that is stored on the
token. The decoder polls for the presence of a token.
Once detected the decoder reads the serial number. If
the token has been learned, the decoder sends a challenge and reads the token’s response. The decoder
uses the encoder key stored in EEPROM to decrypt the
