Infineon XC866 HOT Microcontrollers work at +140°C

The new XC866 HOT microcontrollers form Infineon is new high temperature 8-bit MCUs. The microcontrollers work in up to +140 degrees C environment, exceed general temperature performance of +85 degrees C for industrial applications and +125 degrees C typical in automotive applications.

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 MCUs feature up to 100,000 read/write cycles at +140 degrees C. This feature makes them currently the only MCUs in the market able to perform such data Flash cycling at high temperatures.

The XC866 HOT family members are based on 8051 / MCS-51 architecture with on-chip Flash memory of 4 kBytes, 8 kBytes or 16 kBytes. Performance and cost-saving features of the XC866 include a 26.67 MHz system frequency, an on-chip oscillator and PLL for clock generation and an embedded voltage regulator supporting single voltage supply of 3.3V or 5.0V. 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 10-bit A/D converter allowing for a conversion time of less than 1.5 microseconds compared to the customary 6 to 10 microseconds; three 16-bit timers; UART; SSC (Synchronous Serial Channel); and on-chip debugging support (JTAG). An XC866 family of compatible 8kB or 16kB ROM versions with +140 degrees C capability will be available also.

In quantities of 10,000, the XC866 HOT is priced at approximately $2.30 per piece.
Development tools including starter kits, documentation, debuggers, and compilers are also available now.
