Compared with Sojourner, which roamed within only a few meters of its lander, the new generation of hopping
machines looks toward much broader horizons--in space or on Earth.
The Frequency Hopping option, provides users with even greater test advantages, including testing of Bluetooth(TM) wireless devices.
Our customers are excited about MicroWAVE6000 and the new Frequency Hopping capability it provides.
Because the Lexus RX 300 sets new performance benchmarks for SUVs, Microchip is proud that Toyota selected its proven KEELOQ code hopping technology for the RKE system," said Kobus Marneweck, product marketing manager for Microchip.
Microchip's patented KEELOQ code hopping technology creates a high degree of security using a long code word length together with encryption and automatic synchronization techniques.
In November 1995, Microchip acquired the KEELOQ code hopping technology, patents and patent applications developed by Nanoteq of South Africa, along with the worldwide marketing rights.
The code hopping technology uses a complex non-linear cryptographic algorithm to encode the transmission sequence.
With several patents issued and pending, the KEELOQ code hopping methodology circumvents code capturing since a different code is used with each successive transmission and a previous code is never accepted again.
The HCS300/HCS301 contains a programmable 28-bit serial number to identify the transmitter and a 64-bit encryption key unique to each device that is used to generate a 32-bit hopping code to practically eliminate the possibility of unwanted access from code grabbing and scanning.
In order to provide the necessary protection when thieves are circumventing these high-tech security measures, code hopping technology is required.
Available for volume shipments April 1996, both devices use the KEELOQ code hopping algorithm which combines high security, a small package outline and an extremely low cost to make this an ideal solution for unidirectional remote-keyless-entry systems.
Prince understands the need for creating highly secure RF systems and selected the KEELOQ code hopping technology because of its versatility, robustness and presence in this market," said Dr.
Microchip today introduced a new family of KEELOQ code hopping devices which provides "rock-solid" security in remote-keyless-entry (RKE) systems using infrared, radio frequency or microwave transmissions, as well as highly secure smart card solutions.
The Keeloq hopping code technology is used for enhanced security in wireless/remote controlled systems using infrared, radio frequency or microwave transmissions, as well as highly secure smart card solutions.
The Keeloq hopping code technology uses a complex non-linear algorithm to encode the transmission sequence.
