DESCRIPTION
The Philips 83C751/87C751 offers the advantages of the 80C51
architecture in a small package and at low cost.
The 8XC751 Microcontroller is fabricated with Philips high-density
CMOS technology. Philips epitaxial substrate minimizes CMOS
latch-up sensitivity.
The 8XC751 contains a 2k
64
five-source, fixed-priority level interrupt structure, a bidirectional
inter-integrated circuit (I
oscillator.
The on-board inter-integrated circuit (I
8XC751 to operate as a master or slave device on the I
area network. This capability facilitates I/O and RAM expansion,
access to EEPROM, processor-to-processor communication, and
efficient interface to a wide variety of dedicated I
