Philips Semiconductors
Preliminary Specification
Single-chip 8-bit microcontroller with CAN controller
P8xC591
2
GENERAL DESCRIPTION
The P8xC591 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 and includes the
successful PeliCAN functionality of the SJA1000 CAN
controller from Philips Semiconductors.
The fully static core provides extended power save
provisions as the oscillator can be stopped and easily
restarted without loss of data. The improved internal clock
prescaler of 1:1 achieves a 500 ns instruction cycle time at
12 MHz external clock rate.
Figure 1 shows a Block Diagram of the P8xC591. The
microcontroller 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 P8xC591 will be offered:
P83C591 (with ROM)
P87C591 (with OTP)
Hereafter these versions will be referred to as P8xC591.
The temperature range includes (max. f
CLK
= 12 MHz):
-40 to +85
°
C version, for general applications
The P8xC591 combines the functions of the P87C554
(microcontroller) and the SJA1000 (stand-alone
CAN-controller) with the following enhanced features:
Enhanced CAN receive interrupt (level sensitive)
Extended acceptance filter
Acceptance filter changeable “on the fly”.
The main differences between P8xC591 and P87C554
are:
CAN-controller on chip
6-input ADC
Low active Reset
44 leads.
