FEATURES
P8xCE598
The P8xCE598 combines the functions of P8XC552
(microcontroller) and the PCA82C200 (Philips
CAN-controller) with the following enhanced features:

•
Additional 256 bytes RAM
•
A CAN-controller instead of the I

GENERAL DESCRIPTION
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 (AV
DD
) and one
analog part ground pin (AV
SS
), 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 (V
DD1
to V
DD4
) and
four digital part ground pins (V
SS1
to V
SS4
) are provided
on the package. These pins, one V
DD
and one V
SS
as a
pair of pins are placed on each of the four sides of the
package to provide:
– V
DD1
/V
SS1
for internal logic (CPU, Timers/counters,
Memory, CAN, UART, ADC)
– V
DD2
/V
SS2
for Port 1, Port 3 and Port 4, and PWM0
and PWM1 outputs
– V
DD3
/V
SS3
for the on-chip oscillator
– V
DD4
/V
SS4
for the Port 0, Port 2, ALE output and
PSEN output.
•
External capacitors should be connected across
associated V
DDx
and V
SSx
pins (i.e. V
DD1
and V
SS1
).
Lead length should be as short as possible. Ceramic
chip capacitors are recommended (100 nF).
•
One CAN supply voltage pin (CV
DD
) and one CAN
ground pin (CV
SS
) 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.
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. f
CLK
= 16 MHz):
• −40
to +85
°C
version, for general applications
• −40
to +125
°C
version for automotive applications.

2.2
Recommendation on ALE
P8xCE598
ALE will retain its normal HIGH value during Idle mode and
a LOW value during Power-down mode while in the ‘RFI
reduction mode’.
Additionally during internal access (EA = 1) ALE will toggle
normally when the address exceeds the internal Program
Memory size. During external access (EA = 0) ALE will
always toggle normally, whether the flag
‘RFI’
is set or not.
For application that require no external memory or
temporarily no external memory: the ALE output signal
(pulses at a frequency of
1
⁄
6
f
OSC
) can be disabled under
software control (bit 5 in PCON SFR:
‘RFI’);
if disabled, no
ALE pulse will occur. ALE pin will be pulled down
internally, switching an external address latch to a quiet
state. The MOVX instruction will still toggle ALE as a
normal MOVX.
