PIC16C433
6.0
LIN bus TRANSCEIVER
The PIC16C433 has an integrated LIN bus transceiver,
which allows the microcontroller to communicate via a
LIN bus. The LIN bus protocol is handled by the micro-
controller. The conversion from 5V signal to LIN bus
signals is handled by the transceiver
6.1
The LIN bus Protocol
The LIN bus protocol is not described within this docu-
ment. For further information regarding the LIN bus
protocol, please refer to www.lin-subbus.de.
6.2
LIN bus Interfacing
The LIN bus will be transmitted by toggling the LINTX
bit in the LININTF register. Data transmitted on the LIN
bus is read by checking the LINRX bit in the PORTA
register.
For a LIN bus Slave software implementation, please
refer to AN729.
6.3
LIN bus Hardware Interface
Figure 6-1shows how to implement a hardware LIN bus
interface for the PIC16C433.
An external 45V zener diode between VBB and ground,
with a 500
resistor in series with the battery supply
and the VBB pin, protects the PIC16C433 from power
transients.
An external reverse battery blocking diode is used to
provide polarity protection.
6.4
Thermal Shut-down
In thermal shut-down, the LIN bus output is disabled
instantaneously. The output transistor is turned off,
regardless of the input level at pin LINTX bit and only a
limited current can flow into the receiver connected to
the LIN bus pin.
6.5
Wake-up from SLEEP upon Bus
Activity
The PIC16C433 can wake-up from SLEEP upon bus
activity in the following way:
1.
Connect BACT to GP2/T0CKI/AN2/INT.
The BACT signal is a mirror of the LIN bus. This signal
can be routed to GP2/T0CKI/AN2/INT pin. The GP2/
T0CKI/AN2/INT interrupt wakes up the device from
SLEEP.
