DESCRIPTION
The Philips 83C748/87C748 offers the advantages of the 80C51
architecture in a small package and at low cost.
The 8XC748 Microcontroller is fabricated with Philips high-density
CMOS technology. Philips epitaxial substrate minimizes CMOS
latch-up sensitivity.
The 8XC748 contains a 2k
64
four-source, fixed-priority level interrupt structure, and an on-chip
oscillator.
