XC866 HOT MCU from Infineon

Infineon Technologies has announced the availability of an 8bit embedded flash MCU family that is qualified for operation at up to 140C. The new XC866 HOT MCUs exceed today's maximum temperature performance of 85C for industrial applications and 125C typical in automotive applications. This makes them suitable for use in system designs with high environmental or operating temperatures that would typically require costly and complex heat dissipation or cooling systems. The new XC866 HOT products can now be applied directly onto the application diminishing the need for elaborate cooling and thus reducing overall system cost.

Industrial, automotive apps
In the industrial sector, such high-temperature applications include motor controls for heating and furnace systems, and electronic controls embedded inside motor drives. Automotive applications that require extended temperature ranges include cooling fans located close to the engine, throttle controls and turbochargers.

The XC866 HOT 8bit MCUs with embedded flash memory feature up to 100,000 read/write cycles at 140C. This feature makes them currently the only MCUs in the market able to perform such data flash cycling at high temperatures, according to the company.

The XC866 HOT family members are based on the standard 8051 architecture with on-chip flash memory of 4-, 8- or 16Kbytes. Performance and cost-saving features of the XC866 include a 26.67MHz system frequency, an on-chip oscillator and PLL for clock generation and an embedded voltage regulator supporting single voltage supply of 3.3V or 5V.

Powerful peripherals
The MCUs feature a set of powerful peripherals, including a high-performance capture compare unit enabling flexible PWM signal generation with special modes for motor control; a fast 8-channel 10bit ADC allowing for a conversion time of less than 1.5?s compared to the customary 6-10?s; three 16bit timers; UART; synchronous serial channel; and on-chip debugging support. An XC866 family of compatible 8Kbytes or 16Kbytes ROM versions with 140C capability will also be available to offer even further cost saving potential.

XC866 HOT MCUs are fully qualified and currently available in volume production.

The XC866 comes in a green TSSOP-38 package for the -40C to 140C temperature range. A full suite of low-cost development tools including starter kits, documentation, debuggers and compilers are available today.

In quantities of 10,000, the XC866 HOT is priced at approximately $2.30 per piece.
