1999 Microchip Technology Inc.PreliminaryDS21137E-page 1 FEATURES Security • Programmable 28-bit serial number • Programmable 64-bit encryption key • Each transmission is unique • 66-bit transmission code length • 32-bit hopping code • 34-bit fixed code (28-bit serial number, 4-bit button code, 2-bit status) • Encryption keys are read protected Operating • 2.0—6.3V operation • Four button inputs • No additional circuitry required • 15 functions available • Selectable baud rate • Automatic code word completion • Battery low signal transmitted to receiver • Non-volatile synchronization data Other • Easy to use programming interface • On-chip EEPROM • On-chip oscillator and timing components • Button inputs have internal pulldown resistors • Current limiting on LED output • Minimum component count • Synchronous transmission mode Typical Applications The HCS300 is ideal for Remote Keyless Entry (RKE) applications. These applications include: • Automotive RKE systems • Automotive alarm systems • Automotive immobilizers • Gate and garage door openers • Identity tokens • Burglar alarm systems DESCRIPTION The HCS300 from Microchip Technology Inc., is a code hopping encoder designed for secure Remote Keyless Entry (RKE) systems. The HCS300 utilizes the ® code hopping technology, which incorporates high security, a small package outline and low cost to make this device a perfect solution for unidirectional remote keyless entry systems and access control systems.

Microchip’s Secure Data Products are covered by some or all of the following patents: Code hopping encoder patents issued in Europe, U.S.A., and R.S.A. — U.S.A.: 5,517,187; Europe: 0459781; R.S.A.: ZA93/4726 21137e.Book Page 1 Monday, October 4, 1999 8:04 AM HCS300 DS21137E-page 2Preliminary 1999 Microchip Technology Inc. The HCS300 combines a 32-bit hopping code generated by a non-linear encryption algorithm, with a 28-bit serial number and six status bits to create a 66- bit transmission stream. The length of the transmission eliminates the threat of code scanning and the code hopping mechanism makes each transmission unique, thus rendering code capture and resend (code grab- bing) schemes useless. The encryption key, serial number, and configuration data are stored in EEPROM, which is not accessible via any external connection. This makes the HCS300 a very secure unit. The HCS300 provides an easy to use serial interface for programming the necessary security keys, system parameters, and configuration data. The encyrption keys and code combinations are pro- grammable but read-protected. The keys can only be verified after an automatic erase and programming operation. This protects against attempts to gain access to keys and manipulate synchronization values. The HCS300 operates over a wide voltage range of 2.0V to 6.3V and has four button inputs in an 8-pin configuration. This allows the system designer the freedom to utilize up to 15 functions. The only components required for device operation are the but- tons and RF circuitry, allowing for a very low system cost. 1.0SYSTEM OVERVIEW Key Terms • Manufacturer’s code - a 64-bit word, unique to each manufacturer, used to produce a unique encryption key in each transmitter (encoder). • Encryption Key - a unique 64-bit key generated and programmed into the encoder during the manufacturing process. The encryption key controls the encryption algorithm and is stored in EEPROM on the encoder device. 1.1Learn The HCS product family facilitates several learn strate- gies to be implemented on the decoder. The following are examples of what can be done. It must be pointed out that there exists some third-party patents on learn- ing strategies and implementation. 1.1.1NORMAL LEARN The receiver uses the same information that is trans- mitted during normal operation to derive the transmit- ter’s secret key, decrypt the discrimination value and the synchronization counter. 1.1.2SECURE LEARN* The transmitter is activated through a special button combination to transmit a stored 48-bit value (random seed) that can be used for key generation or be part of the key. Transmission of the random seed can be dis- abled after learning is completed. The HCS300 is a code hopping encoder device that is designed specifically for keyless entry systems, primarily for vehicles and home garage door openers. It is meant to be a cost-effective, yet secure solution to such systems. The encoder portion of a keyless entry system is meant to be held by the user and operated to gain access to a vehicle or restricted area. The HCS300 requires very few external components (Figure 2-1). Most keyless entry systems transmit the same code from a transmitter every time a button is pushed. The relative number of code combinations for a low end system is also a relatively small number. These shortcomings provide the means for a sophisticated thief to create a device that ‘grabs’ a transmission and re-transmits it later or a device that scans all possible combinations until the correct one is found. The HCS300 employs the code hopping technology and an encryption algorithm to achieve a high level of security. Code hopping is a method by which the code transmitted from the transmitter to the receiver is different every time a button is pushed. This method, coupled with a transmission length of 66 bits, virtually eliminates the use of code ‘grabbing’ or code ‘scanning’. As indicated in the block diagram on page one, the HCS300 has a small EEPROM array which must be loaded with several parameters before use. The most important of these values are: • A 28-bit serial number which is me…
