CAN BUS MODULE DESCRIPTION
Introduction
The 33742 features a high-speed CAN physical interface for
bus communication between 60 kbps up to 1.0 Mbps.
Figure 16
below is a simplified block diagram of the CAN interface of the
33742.
Figure 16. Simplified Block Diagram of CAN Interface
CAN Interface Supply
The supply voltage for the CAN driver is the V2 terminal. The
CAN interface has also a supply path from the battery line,
through the V
SUP
terminal. This path is used in CAN Sleep
mode to allow wake-up detection.
During CAN communication (transmission and reception),
the CAN interface current is sourced from the V2 terminal.
During CAN low power mode, the current is sourced from the
V
SUP
terminal.
Main Operation Modes Description
The CAN interface of the 33742 has two main operation
modes: TXRX and Sleep mode. The modes are controlled by
the CAN SPI Register. In the TXRX mode, which is used for
communication, four different slew rates are available for the
user. In the Sleep mode, the user has the option of enabling or
disabling the remote CAN wake-up capability.
CAN Driver Operation in TXRX Mode
When the CAN interface of the 33742 is in TXRX mode, the
driver has two states: recessive or dominant. The driver state is
controlled by the TXD terminal. The bus state is reported
through the RXD terminal.
When TXD is HIGH, the driver is set in recessive state, and
CANH and CANL lines are biased to the voltage set at V2
divided by 2, or approximately. 2.5 V.
When TXD is LOW, the bus is set into dominant state: CAN L
and CANH drivers are active. CANL is pulled to ground, and
CANH is pulled HIGH toward 5.0 V (voltage at V2).
The RXD terminal reports the bus state: CANH minus CANL
voltage is compared versus an internal threshold (a few
hundred millivolts). If CANH minus CANL is below the
threshold, the bus is recessive and RXD is set HIGH. If CANH
minus CANL is above the threshold, the bus is dominant and
RXD is set LOW. This is illustrated in
Figure 16
, page 29.
