The XC866 HOT family members are based on the standard 8051 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 3.3 V or 5.0 V. 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 AD converter allowing for a conversion time of less than 1.5 microseconds (µs) compared to the customary 6 to 10 µs; three 16-bit timers; UART; SSC (Synchronous Serial Channel); and on-chip debugging support (JTAG). An XC866 family of compatible 8 kBytes or 16 kBytes ROM versions with +140°C capability will also be available to offer even further cost saving potential.
In quantities of 10,000, the XC866 HOT is priced at approximately Euros 1.80 (US-$ 2.30) per piece.
