The Intel 8XL51FA 8XL51FB 8XL51FC is a single-chip control oriented microcontroller which is fabricated on
Intel’s reliable CHMOS III-E technology Being a member of the MCS 51 microcontroller family the
8XL51FA 8XL51FB 8XL51FC uses the same powerful instruction set has the same architecture and is pin-
for-pin compatible with the existing MCS 51 microcontroller products
The 8XL51FX is a 3V version of current 8XC51FX and will operate from 2 7V to 3 6V at a frequency range of
3 5 MHz to 16 MHz (Express) 20 MHz (Commercial)
