XC2700

Infineon Technologies AG has launched the new XC2700 family of microcontrollers targeting the growing market for motorcycle engine control.

The new MCUs with 32bit performance will allow system makers to build cost-effective electronic engine control in motorcycles around the world to meet upcoming emission standards. China and India, the world's largest motorcycle markets, are also developing tougher emission control standards for vehicles in the upcoming years, driving the need for cost-effective electronic engine management systems. Despite enhanced requirements regarding reduction of fuel consumption and emission, motorcycles in these regions must meet consumer price demands of less than $500.

The XC2700 family is based on the C166SV2 high-performance MCU core, providing single cycle execution from a 66MHz five-stage pipeline at up to 80MHz. It also integrates key peripherals such as memory, voltage regulator and interfaces to reduce the overall system cost and make the family a cost-effective solution. This also means that software developed for existing C166SV2 controllers can be easily reused with this new family.

The XC2700 product portfolio will include ten products. Infineon is introducing the first XC2700 family membersthe XC2766X and XC2786X. The MCUs integrates an ADC with 16 to 24 channels for linking directly to sensors for a low-cost implementation and two CAN interfaces. It also includes a Universal Serial Interface to link to external peripherals via a UART, LIN or I? C interface. Integrating up to 768Kbytes of 130nm embedded flash, 64Kbytes of data flash and 51Kbytes of system RAM also simplifies the design of the electronic engine management system and keeps costs under control.

With 64- to 176-pins, the XC2700 family also provides a scalable package range from lower cost versions to higher performance devices. Designers can easily move the performance curve to provide engine control systems for motorcycles and entry-level cars. The integration and high performance of the family allows electronic engine control to be implemented in low- cost vehicles, bringing more efficiency and significantly improved emissions performance to a growing market.

AUTOSAR drivers for XC2700 are verified by the AUTOSAR validator project. The driver portfolio comprises components of the microcontroller abstraction layer CAN transceiver and flash EEPROM emulation within one configuration tool for quickly starting up an application development. This is the basis for the complete AUTOSAR Basic Software supported via software partners.

"Electronic engine management for motorcycles requires a cost-effective, high performance solution," said Jochen Hanebeck, senior VP and general manager of the microcontrollers business unit at Infineon. "The new XC2700 family helps reduce the system cost of the engine management system while providing the performance that is needed to meet the legislation on emissions around the world."

Samples of the XC2766X and XC2786X in the XC2700 family are available for dedicated automotive customers. Sample pricing varies according to product specification. The XC2766X with 66MHz frequency, 768kBytes of flash memory, 16 channels, LQFP-100 package and an automotive temperature range of -40C to 125C is priced at $7.45 per piece in quantities of 20,000. For the same quantities and key features in a LQFP-144 package, the XC2786X with 24 channels is priced at $9.15 per device.
