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 to prevent  
its voltage drop from significantly degrading system noise  
margins.
