Infineon Technologies AG provides 8-, 16-, and 32-bit microcontrollers for automotive and industrial control systems with dedicated hardware peripherals that reduce software overhead and external components. In 2010, Infineon introduced its AUDO MAX family of 32-bit microcontrollers targeting automotive powertrain and chassis applications. The initial series of four devices is intended for design of engine management systems meeting the strict Euro 5 and Euro 6 emission standards for combustion vehicles and the electrification of powertrain functions in electrical vehicles. Features include maximum clock frequencies up to 300MHz, high-speed interfaces like SENT and FlexRay, and comprehensive support for advanced safety engineering by using the PRO-SIL features of the devices. A bare die version is suited for use at temperatures of up to 170 °C.
In 2010 Infineon continues to add high- and low-end derivatives to the XE166 and XC2000 families of 16-bit digital signal controllers. All derivatives maintain a high degree of code and pin compatibility to enable developers to optimize features and cost for any design while maintaining a migration path for the future.
In its 8-bit family, Infineon in 2010 introduced devices that operate at up to 150 °C ambient temperature, meeting the rigorous AEC-Q100 standard for use in automotive and industrial electronics application environments. Specified without limitations for the temperature range from -40 °C up to 150 °C, the new XC800 150°C family provides an alternative for harsh operating environments. Based on an 8051 processor core, the family offers different flash memory sizes (4 to 32-kbytes) and integrates such features as oscillator, voltage regulator, EEPROM and supervisory circuits to reduce overall system costs. XC800 150°C microcontrollers featuring on-chip CAN modules reduce the CPU load by performing most of the functions required by the networking protocol (masking, filtering and buffering of CAN frames). In addition, devices in the XC800 150°C family are equipped with a 16-bit vector computer supporting trigonometric calculations needed for field oriented motor control (FOC).
Infineon also introduced the new XC82x and XC83x low cost low pin count families of 8-bit microcontrollers. In addition to the standard peripherals of the other XC800 devices, these new cost optimized products include some new features such as Matrix LED control and Capacitive Touch Sense.
