9 n LIN Slaves The growing functionality in cars also results in an increase in human interactions. Former simple things like switch modules have to become more intelligent in order to reduce wiring effort and to save copper. In today’s vehicle architecture, these switch modules are therefore not directly wired anymore, but they will be connected to a LIN bus system (Local Interconnect network). Melexis launched a new chip family of intelligent network capable switch controllers called “uniROM switch slaves” to support this trend and to keep the development effort as low as possible. This family of chips accomplishes a unique combination of hardware and software. It is a perfect example of how thoughtful application of technology can remove the need for software development and qualifications. UniROM switch slaves for LIN networks can be found in switch modules on the steering wheel, in the car door, in the car roof and in the center console. The LIN bus system is also used more often for different kinds of applications such as intelligent sensors or actuators. LIN applications may also be realized with discrete microcontrollers. In such implementations a System Basis IC (SBC) is required to provide the physical bus interface functionality. SBC’s simplify our customer’s development efforts and decrease module cost. This enables the deployment of LIN bus control for a wider range of applications. Wireless n Wireless ICs During the last ten years, the Wireless Business Unit of Melexis successfully brought short range connectivity and identification solutions to the markets with its leading edge RF and RFID ICs. The frequency coverage of our wireless products is from a few kHz up to 950MHz. In the automotive area, RF transceivers, receivers and transmitters are widely used in remote keyless entry (RKE) and tire pressure monitoring systems (TPMS), whereas RFID readers and transponders are the building blocks of car immobilizers. Hall effect Sensor ICs Triaxis® Hall ICs Wireless ICs Infrared and Opto ICs SensorEyeC™ Opto ICs Camera Sensor ICs Pressure Sensor ICs Sensor Interface ICs Bus ICs Motor Control ICs Hardware and Evaluation Boards In industrial markets, our products are key elements of logistic and traceability applications. We also provide our ICs in home and building automation equipment like garage door openers, alarm systems, access control and automatic meter reading (AMR). In the consumer market, RFICs are used in remote controls for brown goods and our RFID technology is successfully integrated in NFC platform for mobile phones. An open mindset to understand our customer challenges, a strong system and application knowledge, a large capabilities spectrum to convert requirements into “systems on chip” are part of our core competencies. Combined with the sensing expertise available within Melexis, the Wireless Business Unit builds a market leading position in the Wireless Sensing area. Our next product generation will bring even more innovation to our customers and provide them with highly integrated solutions. In the automotive area, we will strengthen our position in TPMS and Passive Entry and Start (PASE) systems. In industrial applications, we will focus on assets and cold chain management with specialty sensor transponders and active RFID tag ICs. We also target medical monitoring and control applications.
