Infineon Received Technical Development Award from Automotive System Supplier Denso for First Tire Pressure Sensor Chip Supporting Built-In Autolocation

Neubiberg, Germany – July 30, 2012 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) today announced that it received a 2011 Technical Development Award from the automotive system supplier Denso Corporation. Denso recognized Infineon for its development of a specific tire pressure sensor chip which enables Denso to realize a more cost effective system and supports built-in autolocation. The Tire Pressure Monitoring System (TPMS) sensors of Infineon support direct systems, where the tire pressure is measured inside the tire and the pressure value is transmitted via RF to the receiving unit of the car. In this regard autolocation means that the system automatically correlates the four received pressure signals with the appropriate four tire positions. Every year, Denso presents its awards to its best suppliers for quality, pricing, technical development, and global collaboration. Infineon is the first non-Japanese component supplier to receive a Denso Technical Development Award. Tire pressure monitoring systems are designed to monitor the air pressure of tires and to alert the driver in case of pressure loss. The introduction of TPMS is mostly driven by legislation to prevent accidents due to unproper air pressure of tires. Today, TPMS is mandatory in the USA where since 2007 all passenger cars and light trucks with a weight less than 10,000 lbs (4,536 kg) have to be equipped with TPMS. Beginning in November 2014, TPMS will be required for all new cars sold in the European Union and South Korea.   Infineon offers the broadest portfolio of TPMS sensors in the market covering different pressure ranges, suiting all kind of vehicles ranging from small cars up to heavy duty trucks and including virtually all types of localization methods (e.g. LF antennas or ±1g). Infineon has shipped more than 150 million TPMS sensors which makes the company the leading provider of TPMS sensors for automotive system suppliers. Infineon is the world’s second largest automotive semiconductor supplier According to the latest report of the market research company Strategy Analytics, Infineon is the foremost non-Japanese supplier of automotive semiconductors in the Japanese market, with a market share of 3.8 percent. Globally, Infineon ranks number two in automotive semiconductors, with a 10 percent share of a market worth about US $23 billion in 2011. In Europe, which is the center of innovation in the field of automotive electronics, Infineon has remained the unchallenged market leader for many years, and currently has a market share of 14.7 percent.
