... GENERAL DESCRIPTION The HCS410/ transponder device designed for secure entry systems. The HCS410/WM utilizes bi- directional 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 pack- age. Preliminary Oscillator Power Control Configuration Register ...

... 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 ...

... IFF, while IFF2 allows two keys to be used. 3.1 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 ...

... HCS410/WM Responses The responses from the HCS410/WM are in PPM for- mat. See Figure 3-3 for additional information. Every response from the HCS410 is preceded by a “2 bit pre- amble” and then 16/32 bits of data. 2 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 ...

... LC0 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 whenever the E HCS410/WM is expecting data from the decoder. The intelligent damping pulses start 64 T acknowledge pulses have been sent and continue for the HSC410 detects data from the base station ...

... HCS410/WM 5.0 INTEGRATING THE HCS410/WM INTO A SYSTEM Use of the HCS410/ system requires a compat- ible 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 per- form IFF functions are available. These routines pro- vide system designers the means to develop their own decoding system ...

... The decoder uses the encoder key stored in EEPROM to decrypt the 2001 Microchip Technology Inc. HCS410/WM response. The decrypted response is compared to the challenge. If they match, then identification was suc- cessful and the appropriate response is generated. ...
