NCV7356
Single Wire CAN Transceiver
The NCV7356 is a physical layer device for a single wire data link
capable of operating with various Carrier Sense Multiple Access
with Collision Resolution (CSMA/CR) protocols such as the Bosch
Controller Area Network (CAN) version 2.0. This serial data link
network is intended for use in applications where high data rate is not
required and a lower data rate can achieve cost reductions in both the
physical media components and in the microprocessor and/or
dedicated logic devices which use the network.
The network shall be able to operate in either the normal data rate
mode or a high−speed data download mode for assembly line and
service data transfer operations. The high−speed mode is only
intended to be operational when the bus is attached to an off−board
service node. This node shall provide temporary bus electrical loads
which facilitate higher speed operation. Such temporary loads should
be removed when not performing download operations.
The bit rate for normal communications is typically 33 kbit/s, for
high−speed transmissions like described above a typical bit rate of
83 kbit/s is recommended. The NCV7356 features undervoltage
lockout, timeout for faulty blocked input signals, output blanking
time in case of bus ringing and a very low sleep mode current.
The device is compliant with GMW3089V2.4
General Motors Corporation specification.

FUNCTIONAL DESCRIPTION
TxD Input Pin
TxD Polarity
• TxD = logic 1 (or floating) on this pin produces an
undriven or recessive bus state (low bus voltage)
• TxD = logic 0 on this pin produces either a bus normal
or a bus high voltage dominant state depending on the
transceiver mode state (high bus voltage)
If the TxD pin is driven to a logic low state while the sleep
mode (Mode 0 = 0 and Mode 1 = 0) is activated, the
transceiver can not drive the CANH pin to the dominant
state.
The transceiver provides an internal pullup current on the
TxD pin which will cause the transmitter to default to the
bus recessive state when TxD is not driven.
TxD input signals are standard CMOS logic levels.
Timeout Feature
In case of a faulty blocked dominant TxD input signal,
the CANH output is switched off automatically after the
specified TxD timeout reaction time to prevent a dominant
bus.
The transmission is continued by next TxD L to H
transition without delay.
MODE0 and MODE1 Pins
The transceiver provides a weak internal pulldown
current on each of these pins which causes the transceiver
to default to sleep mode when they are not driven. The
mode input signals are standard CMOS logic level for
3.3 V and 5 V supply voltages. See Electrical
Characteristics table for timing limitations for mode
changes.

High−Speed Mode
High Voltage Wake−Up
Normal Mode
Sleep Mode
Transceiver is in low power state, waiting for wake−up
via high voltage signal or by mode pins change to any state
other than 0,0. In this state, the CANH pin is not in the
dominant state regardless of the state of the TxD pin.
High−Speed Mode
This mode allows high−speed download with bit rates up
to 100 Kbit/s. The output wave shapingaping circuit is
disabled in this mode. Bus transmitter drive circuits for
those nodes which are required to communicate in
high−speed mode are able to drive reduced bus resistance
in this mode.
High Voltage Wake−Up Mode
This bus includes a selective node awake capability,
which allows normal communication to take place among
some nodes while leaving the other nodes in an undisturbed
sleep state. This is accomplished by controlling the signal
voltages such that all nodes must wake−up when they
receive a higher voltage message signal waveform. The
communication system communicates to the nodes
information as to which nodes are to stay operational
(awake) and which nodes are to put themselves into a non
communicating low power “sleep” state. Communication
at the lower, normal voltage levels shall not disturb the
sleeping nodes.
Normal Mode
Transmission bit rate in normal communication is
33 Kbits/s. In normal transmission mode the NCV7356
supports controlled waveform rise and overshoot times.
Waveform trailing edge control is required to assure that
high frequency components are minimized at the
beginning of the downward voltage slope. The remaining
fall time occurs after the bus is inactive with drivers off and
is determined by the RC time constant of the total bus load.
RxD Output Pin
Logic data as sensed on the single wire CAN bus.
RxD Polarity
• RxD = logic 1 on this pin indicates a bus recessive
state (low bus voltage)
• RxD = logic 0 on this pin indicates a bus normal or
high voltage bus dominant state
RxD in Sleep Mode
RxD does not pass signals to the microprocessor while in
sleep mode until a valid wake−up bus voltage level is
received or the MODE0 and MODE 1 pins are not 0, 0
respectively. When the valid wake−up bus voltage signal
awakens the transceiver, the RxD pin signals an interrupt
(logic 0). If there is no mode change within 250 ms (typ),
the transceiver re−enters the sleep mode.
When not in sleep mode all valid bus signals will be sent
out on the RxD pin.
RxD will be placed in the undriven or off state when in
sleep mode.
RxD Typical Load
Resistance: 2.7 kW
Capacitance: < 25 pF
