The HCS410/WM utilizes bidirectional challenge-and-response for logical and physical access control. The HCS410/WM integrates an LC-resonant circuit with the HCS410 silicon into a leadless SOT-385 package. Response KEELOQ is a registered trademark of Microchip Technology, Inc.

Preliminary DS41116B-page 1 Register HCS410/WM 1.0 1.1 SYSTEM OVERVIEW Key Terms 1.2 KEELOQ IFF * 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. 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. 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.

HCS410/WM 2.0 DEVICE DESCRIPTION 3.0 DEVICE OPERATION 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. 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. FIGURE 2-1: 1 TRANSPONDER CIRCUIT 8 3.1 IFF Mode Activation 2 3 4 7 6 5 CPOOL CRES LRES 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. HCS410 3.2 IFF Decoder Commands As shown in Figure 3-1, a logic 1 and 0 are differentiated by the time between two rising edges. A long pulse indicates a 1; a short pulse, a 0.

Every response from the HCS410 is preceded by a "2 bit preamble" of 012, and then 16/32 bits of data. 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. When writing to the serial number or configuration word, the user must send the transport code before the write will begin. Note: If the configuration word is written, the device must be reset to allow the new configuration settings to come into effect. 3.4 IFF Response 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. 3.6 IFF Read 3.5 IFF Write 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. The decoder can write to USER[0:3], SER[0:1], and the configuration word in the EEPROM.

Preliminary DS41116B-page 5 HCS410/WM 3.7 3.7.1 IFF Special Features 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. FIGURE 3-4: TE SERIAL NUMBER CORRECT ACKNOWLEDGE SEQUENCE LC0/1 3 TE TE 3 TE 3.7.2 INTELLIGENT DAMPING If the IDAMP bit is set to 0, the HCS410/WM will clamp the LC pins for 5 s 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. DS41116B-page 6 Preliminary 2001 Microchip Technology Inc. HCS410/WM 4.0 EEPROM ORGANIZATION AND CONFIGURATION 4.6 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. 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. TABLE 4-1: Symbol IDAMP IFF2 OSC0:3 IFFB ACOLI 4.6.1 CONFIGURATION OPTIONS Description 4.1 IFF Programming Intelligent Damping for High Q LC Tank. Enable IFF2 key Onboard Oscillator Tuning Bits Transponder Baud Rate Anti Collision Communication Enable 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. 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. IDAMP: INTELLIGENT DAMPING If IDAMP is set to `1' intelligent damping is disabled. 4.6.2 4.6.3 IFF2: ENABLE IFF2 KEY OSC: OSCILLATOR TUNING BITS These bits allow the onboard oscillator to be tuned to within 10% of the nominal oscillator speed over both temperature and voltage.

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. Nominal Slower 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. Slowest IFFB: TRANSPONDER BAUD RATE 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. This selects the baud rate for IFF communications for a TE of 200 s. 4.6.5 ACOLI: ANTI-COLLISION 4.5 User Data The 64-bit user EEPROM can be reprogrammed and read at any time using the IFF interface. If ACOLI is set, the anti-collision operation during bidirectional transponder mode (IFF) is enabled. This feature is useful in situations where multiple transponders enter the magnetic field simultaneously. 2001 Microchip Technology Inc. Preliminary DS41116B-page 7 HCS410/WM 5.0 INTEGRATING THE HCS410/WM INTO A SYSTEM 5.1 Key Generation 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. 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.

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. DS41116B-page 8 Preliminary 2001 Microchip Technology Inc.

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.
