1999 Apr 15
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
×
8 ROM (83C748) EPROM (87C748), a
64
×
8 RAM, 19 I/O lines, a 16-bit auto-reload counter/timer, a
four-source, fixed-priority level interrupt structure, and an on-chip
oscillator.
