Infineon MCUs target fuel consumption, emissions reduction

Jan. 30, 2008
Infineon has introduced a new generation of 32-bit AUDO microcontrollers (MCUs), targeting next-generation emission standards and other powertrain and chassis applications.

Infineon has introduced a new generation of 32-bit AUDO microcontrollers (MCUs), targeting next-generation emission standards and other powertrain and chassis applications.

The AUDO FUTURE family is fully compatible with AUDO- NextGeneration (NG) devices. Both families are based on Infineon's TriCore core, which combines microcontroller and digital signal processing (DSP) functions with flash memory.

The AUDO FUTURE family includes the 80MHz TC1736 with 1Mbyte (MB) of flash memory, the 80MHz or 133MHz TC1767 with 2MB of flash, and the 180MHz TC1797 with 4 Mbytes (MB) of flash and an integrated FlexRay controller. The FlexRay core integrated into the TC1797 is based on Infineon's discrete CIC-310 FlexRay controller.
On-chip peripherals are handled by a dedicated, programmable peripheral control processor (PCP) engine in AUDO FUTURE MCUs, thus allowing the TriCore core to focus on engine management, transmission control and other powertrain functions.

Jochen Hanebeck, senior vice president and general manager of Infineon's Microcontrollers business unit, says every second automobile in Europe and every third car made worldwide contains an Infineon microcontroller for diesel or gas engine and transmission control systems, to control functions such as injection, ignition and exhaust gas recirculation.

Hanebeck says compatibility with older Infineon MCUs makes it easier for application developers to upgrade their designs to accommodate new emission standards.

"With up to 66% higher performance than previous AUDO Next-Generation products, the AUDO FUTURE family is ideally suited for the upcoming OBD2 on-board diagnostics standard for self-diagnostic functions and emission standards such as EURO5 and EURO6, and Tier2/Bin5 in the U.S.," Hanebeck says. "These new emission standards require more complex algorithms and more performance, and the density of embedded flash (in AUDO FUTURE MCUs) allows all the code to sit in the single chip."

"The higher performance also allows AUTOSAR standard software to be used without impacting the control algorithms, allowing developers to access the ecosystem of existing software development tools and develop higher quality code more quickly."

Hanebeck adds that the TC1797 allows developers to run all application-specific tasks on a single core while the peripheral control processor drives all the on-chip peripherals in parallel. "Due to its high level of performance, we expect that migration to symmetrical dual-core architectures in powertrain systems and major software conversions will not be necessary during the next years," he contends.

The Infineon AUDO FUTURE family ranges in price from approximately €10 (about $14.50) to approximately €20 (about $29) in volumes of 100,000, depending on the configuration and packaging. Samples are available now. The family comes in Low-Quad Flat Pack (LQFP) packages with 144 or 176 pins or Ball-Grid-Array (BGA) packages with 260 or 416 balls. High-volume production is expected to begin in 2009.
