Cobham Semiconductor Solutions’ (formerly Aeroflex) UT64CAN333x series of Controller Area Network (CAN) transceivers
are developed in accordance with the ISO 11898-2 and 11898-5
standards. The CAN transceiver provides the physical layer that
permits operation on a differential CAN bus. This series of CAN
transceivers are capable of baud rates between 10 kbps to 8
Mbps and include a slope-control mode to control the slew rate
of the transmissions for baud rates of up to 500kbps. A standby
mode disables the transmitter circuit to conserve power while
monitoring the bus for activity. The UT64CAN333x series of
transceivers can support up to 120 nodes.
The three transceiver options are:



The UT64CAN3330 provides a low power sleep mode of
operation.
The UT64CAN3331 supports a bus isolated diagnostic
loopback.
The UT64CAN3332 offers the ability to monitor bus traffic
enabling the local controller to change its baud rate to
match the operations of the bus.
Applications
Avionic/Aerospace sensor monitoring
Avionic/Aerospace system telemetry
Avionic/Aerospace command and control
Utility Plane Communication
Smart Sensor Communication
ARINC825 applications
Time Triggered (TTP/C and TTP/A) applications

Overview
Overview
The UT64CAN333x series CAN transceivers are low power serial communications devices developed to handle the demands
of harsh space and terrestrial environments. The UT64CAN333x transceivers are compatible with the ISO 11898-2 and
11898-5 standards and operate as the physical layer between the bus and the CAN controller. All of the transceivers operate
on a single +3.3V power supply and receive data with an input common-mode in the range of -7V to +12V. The CANH and
CANL outputs are fault protected against short-circuits by over-current shutdown circuitry. Each UT64CAN333x CAN
transceiver is capable of:





Operations on any 5V bus or 3V bus
Being a cold spare back-up to an active transceiver
Programmable slew control on the bus driver
Operating at baud rates up to 8 Mbps
Low-power standby mode. The standby mode permits the transceiver to enter a low-current, listen only, mode by
disabling the driver while the receiver remains active. The local controller has the option to disable low-power standby
mode when bus activity resumes
Along with the common functionality just described, the UT64CAN333x family of transceivers includes three
members, each with a unique mode of operation.
The UT64CAN3330, Figure 1, provides the option to place the transceiver into a low power sleep mode to conserves power
when CAN activity is suspended. Sleep mode disables the driver and receiver circuit when the ZZ pin is biased ≤ VIL. The part
resumes operations when the ZZ pin is biased ≥ VIH.

The UT64CAN3331, Figure 2, provides the option to isolate the transceiver bus connections to permit local node
diagnostics, without interrupting operations on the bus. Diagnostic Loopback mode is enabled when the LBK pin is biased ≥
VIH. Diagnostic Loopback mode is disabled when the LBK pin is biased ≤ VIL.

Figure 3 UT64CAN3332 (Autobaud Loopback)
The RS pin on the UT64CAN333x series CAN transceivers provides three functional modes of operation:
1.
High-speed: The high-speed mode of operation is selected by connecting pin 8 directly to ground, allowing the driver
output to achieve a baud rate up to 8 Mbps
2.
Slope control: The rise and fall slopes are adjusted by connecting a resistor to ground at pin 8. The slope of the driver
output signal is proportional to the pin's output current. This slope control is implemented with an external resistor
value between 10kΩ to 100kΩ. These values control to slew rates between ~2.0 V/us to ~20 V/us.
3.
Low-power standby mode: If RS is set to a high-level input (> 0.75*VDD), the transceiver enters a low-current, listen only
mode of operations. In this mode, the CAN bus driver is disabled and the receiver remains active. The CAN controller
has ability to disable low-power standby mode once bus activity resumes.
