8.3 Feature Description
8.3.1 Pin Description
8.3.1.1 TXD
TXD is the logic-level signal, referenced to either VCC or VIO from a CAN controller to the device.
8.3.1.2 GND
GND is the ground pin of the transceiver, it must be connected to the PCB ground.
8.3.1.3 VCC
VCC provides the 5-V nominal power supply to the CAN transceiver.
8.3.1.4 RXD
RXD is the logic-level signal, referenced to either VCC or VIO, from the TCAN1044-Q1 to a CAN controller. This
pin is only driven once VIO is present.
When a wake event takes place RXD is driven low.
8.3.1.5 VIO
The VIO pin provides the digital IO voltage to match the CAN controller voltage thus avoiding the requirement for
a level shifter. It supports voltages from 1.7 V to 5.5 V providing the widest range of controller support.
8.3.1.6 CANH and CANL
These are the CAN high and CAN low differential bus pins. These pins are connected to the CAN transceiver
and the low-voltage WUP CAN receiver.
8.3.1.7 STB (Standby)
The STB pin is an input pin used for mode control of the transceiver. The STB pin can be supplied from either
the system processor or from a static system voltage source. If normal mode is the only intended mode of
operation than the STB pin can be tied directly to GND.
8.3.2 CAN Bus States
The CAN bus has two logical states during operation: recessive and dominant. See Figure 13 and Figure 14.
A dominant bus state occurs when the bus is driven differentially and corresponds to a logic low on the TXD and
RXD pins. A recessive bus state occurs when the bus is biased to VCC/2 via the high-resistance internal input
resistors (RIN) of the receiver and corresponds to a logic high on the TXD and RXD pins.
A dominant state overwrites the recessive state during arbitration. Multiple CAN nodes may be transmitting a
dominant bit at the same time during arbitration, and in this case the differential voltage of the bus is greater than
the differential voltage of a single driver.
The TCAN1044-Q1 transceiver implements a low-power standby (STB) mode which enables a third bus state
where the bus pins are weakly biased to ground via the high resistance internal resistors of the receiver. See
Figure 13 and Figure 14.
