These devices can address up to 64 Kbytes of external program/data memory.
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).
For the remainder of this document, the 8XL52, 8XL54, 8XL58 will be referred to as the 8XL5X, unless
information applies to a specific device.
