The P8xCE598 is a single-chip 8-bit high-performance
microcontroller with on-chip CAN-controller, derived from
the 80C51 microcontroller family.
It uses the powerful 80C51 instruction set.
Figure 1 shows a block diagram of the P8xCE598.
The P8xCE598 is manufactured in an advanced CMOS
process, and is designed for use in automotive and
general industrial applications. In addition to the 80C51
standard features, the device provides a number of
dedicated hardware functions for these applications.
Two versions of the P8xCE598 will be offered:
Hereafter these versions will be referred to as P8xCE598.
The temperature range includes (max. f

The P8xCE598 combines the functions of P8XC552
(microcontroller) and the PCA82C200 (Philips
CAN-controller) with the following enhanced features:
The main differences to the P8xC552 microcontroller are:
2.1
Primary attention is paid to the reduction of
electromagnetic emission of the microcontroller
P8xCE598. The following features reduce the
electromagnetic emission and additionally improve the
electromagnetic susceptibility:
