The Intel 8XL52 8XL54 8XL58 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 8XL52 8XL54
8XL58 uses the same powerful instruction set has the same architecture and is pin-for-pin compatible with
the existing MCS 51 microcontroller products
The 8XL5X is a 3V version of current 8XC5X and will operate from 2 7V to 3 6V at a frequency range of
3 5 MHz to 16 MHz (Express) 20 MHz (Commercial)
