8-bit microcontroller with on-chip CAN
P8xC592
Table 1
Pin description for single function pins (SOT188-2; see note 1)
Notes
1. To avoid a ‘latch up’ effect at power-on: VSS 0.5 V < ‘voltage on any pin at any time’ < VDD + 0.5 V.
2. Triggered by a rising edge. ADC operation can also be started by software.
3. RST also provides a reset pulse as output when timer T3 overows or after a CAN wake-up from Power-down.
4. ALE is activated every six oscillator periods. During an external data memory access one ALE pulse is skipped.
5. See Section 7.1, Table 3 for EA operation. For P83Cxxx microcontrollers specified with the option ‘ROM-code
protection’, the EA pin is latched during reset and is ‘don't care’ after reset, regardless of whether the ROM-code
protection is selected or not.
SYMBOL PIN
DESCRIPTION
VDD
2
Power supply, digital part (+5 V). For normal operation and power reduced modes.
STADC
3
Start ADC operation. Input starting analog-to-digital conversion (note 2). This pin must not oat.
PWM0
4
Pulse width modulation output 0.
PMW1
5
Pulse width modulation output 1.
EW
6
Enable Watchdog Timer (WDT): enable for T3 Watchdog Timer and disable Power-down mode.
This pin must not oat.
RST
15
Reset: input to reset the P8xC592 (note 3).
CVSS
22
CAN ground potential for the CAN transmitter outputs.
XTAL2
33
Crystal pin 2: output of the inverting amplier that forms the oscillator.
When an external clock oscillator is used this pin is left open-circuit.
XTAL1
34
Crystal pin 1: input to the inverting amplier that forms the oscillator, and input to the internal clock
generator. Receives the external clock oscillator signal, when an external oscillator is used.
VSS
35
Ground, digital part.
PSEN
44
Program Store Enable: Read strobe to external Program Memory (active LOW).
Drive: 8
× LSTTL inputs.
ALE
45
Address Latch Enable: latches the Low-byte of the address during accesses to external memory
(note 4). Drive: 8
× LSTTL inputs; handles CMOS inputs without an external pull-up.
EA
46
External Access input. See note 5.
REF
55
1
2AVDD reference voltage output respectively input (note 6).
CRX1
56
Inputs from the CAN-bus line to the differential input comparator of the on-chip CAN-controller
(note 7).
CRX0
57
AVREF
58
Low-end of ADC (analog-to-digital) conversion reference resistor.
AVREF+
59
High-end of ADC (analog-to-digital) conversion reference resistor (note 8).
AVSS
60
Ground, analog part. For ADC, CAN receiver and reference voltage.
AVDD
61
Power supply, analog part (+5 V). For ADC, CAN receiver and reference voltage.
