XC864 - 4 KB Flash 8-bit Microcontroller Series
XC864 - 4 KB Flash 8-bit Microcontroller Series
The XC864 series expands Infineon’s 8-bit XC800 microcontroller family to provide advanced peripheral integration for motor control performance in a small footprint package (TSSOP-20).
XC864 combines a high performance 8051 core with on-chip Flash memory and powerful on-chip peripherals. In addition, further performance and costsaving enhancements to the XC800 family include features such as an on-chip oscillator and embedded voltage regulator (EVR), supporting single voltage supply of 3.3 V or 5.0 V.
