The Intel 8XL528XL548XL58 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 8XL528XL54

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 27V to 36V at a frequency range of

35 MHz to 16 MHz (Express)20 MHz (Commercial)

For the remainder of this document the 8XL52 8XL54 8XL58 will be referred to as the 8XL5X unless

information applies to a specific device
