Notes
1. The following applies to the Absolute Maximum Ratings:
a) Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This
is a stress rating only and functional operation of the device at these or any conditions other than those described
in the Chapters 24 and 25 of this specification is not implied.
b) This product includes circuitry specifically designed for the protection of its internal devices from the damaging
effect of excessive static charge. However, its suggested that conventional precautions be taken to avoid
applying greater than the rated maxima.
c) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect
to VSS unless otherwise noted.
2. This value is based on the maximum allowable die temperature and the thermal resistance of the package, not on
device power consumption.



Description

The P8xC591 is a single-chip 8-bit-high-performance microcontroller, with on-chip CAN-controller, derived from the 80C51 microcontroller family.

P8xC591 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 of P8xC591 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. fCLK = 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.
