Advance Information
33897
33897A
Single-Wire CAN Transceiver
The 33897 provides a physical layer for digital communications purposes
using a Carrier Sense Multiple Access/Collision Resolution (CSMA/CR) data
link operating over a single-wire medium. This is more commonly referred to
as single-wire Controller Area Network (CAN).
SINGLE-WIRE CAN
TRANSCEIVER
The 33897 operates directly from a vehicle's 12 V battery system or a broad
range of DC-power sources. It can operate at either low or high (33.33 kbps
and 83.33 kbps) data rates. A high-voltage wake-up feature allows the 33897
to control the regulator used in support of the MCU and other logic. The 33897
includes a control terminal that can be used to put the module regulator into
Sleep mode. The presence of a defined wake-up voltage level on the bus will
reactivate the control line to turn the regulator and the system back on.
The 33897 complies with the GM3089v2.0 General Motors Corporation
specification.

SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 33897 is intended for use as a physical layer device in a
communications where the radiated EMI of the higher rate
single-wire CAN communications bus. The communications
takes place from a single terminal over a single wire using a
common ground for a current return path. Two data rates are
available, with the high rate used for factory or assembly line
communications and the lower for actual system
could be an issue.
Two terminals control of the mode of operation (sleep, low-
speed, high-speed, and high-voltage wake-up).
BLOCK DIAGRAM COMPONENTS
Timer OSC
TXD BUS DRVR
This circuit generates a 500 kHz signal to be used for internal
logic. It is the reference for some of the required delays.
This circuit drives the BUS. It can drive it with the higher
voltage wake-up signals when enabled by the Mode Control
circuit. It can also provide waveshaping for reduced EMI or not
provide it for the higher data rate mode. The actual data is
received on TXD at CMOS logic levels, then translated by this
circuit to the necessary operating voltages.
Timers
This circuit contains the timing logic used to hold the CNTL
active for the required time after the conditions for sleep mode
have been met. It is also used to keep the TXD driver active for
a period of time after it has generated a passive level on the
bus.
Undervoltage Detect
This circuit monitors internal operating voltage to assure
proper operation of the part. If a low-voltage condition is
detected, it sends a signal to disable the BUS RCVR and TXD
BUS DRVR circuits. This prevents incorrect data from being put
on the bus or sent to the MCU.
Mode Control
This circuit contains the control logic for the various
operating modes and conditions required for the IC.
Load Switch
BUS RCVR
The LOAD switch provides a path for an external resistor
connected to the BUS to be connected to ground. When a loss
of ground is detected, this switch is opened to prevent the
current that would normally be flowing to the ground from the
module from going back through the load resistor and raising
the bus level. The circuit is opened when the voltage between
GND and VBATT becomes too low as would be the case if
module ground were lost.
This circuit translates the levels on the BUS terminal to a
CMOS level indicating the presence of a data 0 or 1. It also
determines the presence of a high-voltage wake-up (HVWU)
signal that is passed to Mode Control and Timers circuits. An
analog filter is used to “de-glitch” the high-voltage wake-up
signal and prevent false exits from the sleep mode.
OPERATION
The 33897 is intended to be used with an MCU to control its
operation and to process and generate the data for the bus.
(recessive) state (bus at near zero volts). When the TXD
terminal is low, the output goes to a driven state. The voltage
and waveshaping in the driven state is determined by the levels
on the MODE0 and MODE1 terminals (refer to Table 2).
Ground Terminals
The four ground terminals are not only for electrical
conduction, their number and locations at each of the four
corners serve also to remove heat from the IC. The biggest
benefit of this is obtained by putting a lot of copper on the PCB
in this area and, if ground is an internal layer, by adding
numerous plated- through connections to it with the largest
diameter holes the layout can use.

Mode Control
CNTL Output
The MODE terminals control the transmitter filtering and
BUS voltage and the IC sleep mode operation. Table 2 shows
the mode versus the logic levels on MODE0 and MODE1.
This logic level signal is used to control a VCC regulator.
When the output is low, the VCC regulator is expected to
shutdown. This is normally used to shut down the MCU and all
the devices powered by VCC when the IC is in sleep mode. This
is done to save power. When the part is taken out of the sleep
mode by the higher-than-normal bus voltage, this terminal is
asserted high and the VCC regulator brings its output up to the
The MODE0 and MODE1 terminals have a weak pulldown in
the IC so that in case the terminals are not driven, the device
will enter the sleep mode. This is usually the situation as the
MCU comes out of reset, before the driving signals have been
configured as outputs.
regulated level. This starts the MCU, which controls the mode
of the IC. The MCU must change the mode signals to non-sleep
mode levels in order to keep this terminal from going low. There
is a delay to allow the MCU to fully wake up and take control
after the high-voltage signaling is removed before the level on
this output returns low. After a delay time, even if the bus is at
high voltage, the IC will return to sleep mode if both MODE
terminals are low.
RX Data
The data received on the bus is translated to logic levels on
this terminal. This terminal is a logic high when the bus is in the
recessive state (near zero volts) and is low when the bus is in
either the normal or high-voltage dominant state.
This is an open-drain type of output that requires an external
resistor to pull it up. When the device is in sleep mode, the
output will be off unless a high-voltage wake-up level is
detected on the bus. If the wake-up level is detected, the output
will be driven by the data on the bus. If the level of the data
returns to normal level, the output will return to off after a short
delay unless a non-sleep mode condition is set by the MCU.
VBATT Input
This power input is not reverse battery protected and should
use an external diode to protect it from damage owing to
reverse battery if this protection is desired. The voltage drop of
the diode must be taken into consideration when the operating
range of the system is being determined. This diode is generally
used to protect the entire module from reverse battery and
should be selected accordingly.
LOAD Switch
This switch is on in all operating modes unless a loss of
ground is detected. If this happens, the switch is opened and
the resistor normally attached to its terminal will be no longer
pass current to or from the bus.
BUS I/O
This input/output may require ESD and/or EMI external
circuitry. A set of components is shown in the Simplified
Application Diagram on the front of this datasheet. The value of
the capacitor should be adjusted downward in direct proportion
to the added capacitance of the ESD or EMI circuits. The series
resistance of the inductor should be kept below 3.5 Ω to prevent
its voltage drop from significantly degrading system noise
margins.
