GENERAL DESCRIPTION
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:
P80CE598 (without ROM)
P83CE598 (with ROM)
Hereafter these versions will be referred to as P8xCE598.
The temperature range includes (max. fCLK = 16 MHz):
40 to +85 °C version, for general applications
40 to +125 °C version for automotive applications.
The P8xCE598 combines the functions of P8XC552
(microcontroller) and the PCA82C200 (Philips
CAN-controller) with the following enhanced features:
32 kbytes Program Memory
2 × 256 bytes Data Memory
DMA between CAN Transmit/Receive Buffer and
internal RAM.
The main differences to the P8xC552 microcontroller are:
32 kbytes programmable ROM (P8xC552 has 8 kbytes)
Additional 256 bytes RAM
A CAN-controller instead of the I2C-serial interface.
2.1
Electromagnetic Compatibility (EMC)
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:
One analog part power supply pin (AVDD) and one
analog part ground pin (AVSS), placed as a pair of pins
on one side of the package (see Fig.3), providing power
supply (+5V) and ground for ADC, CAN receiver and
reference voltage.
Four digital part supply voltage pins (VDD1 to VDD4) and
four digital part ground pins (VSS1 to VSS4) are provided
on the package. These pins, one VDD and one VSS as a
pair of pins are placed on each of the four sides of the
package to provide:
–VDD1/VSS1 for internal logic (CPU, Timers/counters,
Memory, CAN, UART, ADC)
–VDD2/VSS2 for Port 1, Port 3 and Port 4, and PWM0
and PWM1 outputs
–VDD3/VSS3 for the on-chip oscillator
–VDD4/VSS4 for the Port 0, Port 2, ALE output and
PSEN output.
External capacitors should be connected across
associated VDDx and VSSx pins (i.e. VDD1 and VSS1).
Lead length should be as short as possible. Ceramic
chip capacitors are recommended (100 nF).
One CAN supply voltage pin (CVDD) and one CAN
ground pin (CVSS) as a pair of pins placed on one side
of the package providing (digital part) power supply
(+5V) and ground for the CAN transmitter outputs.
Internal decoupling capacitance improves the EMC
radiation behaviour and the EMC immunity.
