These include 5V VCC only, 3.3V VCC only, 5V VCC with I/O level shifting and galvanic-isolated CAN transceivers. These CAN transceiver families include product mixes with varying features such as low power standby modes with and without wake up, silent modes, loop back and diagnostic modes. The Texas Instruments CAN EVM helps designers evaluate the operation and performance of various TI CAN transceivers. It also provides PCB footprints for different bus termination, bus filtering and protection concepts. The CAN EVM is provided with the SN65HVD255 installed. It is easily configured by the customer for the SN65HVD23x, SN65HVD25x, SN65HVD10x0 and SN65HVDA54x CAN transceiver families as needed by jumper settings, simple soldering tasks and replacement of standard components. A separate EVM is available for the galvanic-isolated CAN transceiver family. 1.2 CAN EVM The CAN EVM has simple connections to all necessary pins of the CAN transceiver device, and jumpers where necessary to provide flexibility for device pin and CAN bus configuration. There are test points (loops) for all main points where probing is necessary for evaluation such as GND, VCC, TXD, RXD, CANH, CANL, Pin 8 (mode pin), Pin 5 (various functions). The EVM supports many options for CAN bus configuration. It is pre-configured with two 120Ω resistors that may be connected on the bus via jumpers: a single resistor is used with the EVM as a terminated line end (CAN is defined for 120Ω impedance twisted pair cable) or both resistors in parallel for electrical measurements representing the 60Ω load the transceiver “sees” in a properly terminated network (i.e. 120Ω termination resistors at both ends of the cable). If the application requires “split” termination, TVS diodes for protection, or Common Mode (CM) Choke, the EVM has footprints available for this via customer installation of the desired component(s).

For single-supply transceivers, connect the 5V or 3.3V VCC supply to the TB1 jumper header, or the VCC and GND test-point loops. The power supplied should meet the required specification of VCC for the transceiver being tested. LED D3 is used to indicate VCC presence. 2.1.2 I/O Power Supply VRXD or VIO (JMP2, JMP6 or TP8) For devices with I/O level shifting, a second supply pin for the I/O or RXD pin is on Pin 5 of the transceiver device. A second power supply is needed to test one of these devices and should be connected via JMP2, JMP6 or TP8. A local buffering and decoupling capacitor should be installed at C6 if the EVM is used for one of these devices. 2.1.3 Main Supply and I/O Header (JMP2) All key I/O and supply GND functions are brought to this header. It may be used on either interface to test equipment or a short cable could be made to connect to either an existing customer application board or MCU/DSP EVM board for a processor with a CAN controller Table 2.

Connects to Jumper JMP6 VRXD header to allow flexibility in using device with power supply for I/O on Pin 5 of transceiver. This header is arranged to provide a separate grounds for each signal pair (TXD/GND and RXD/GND). If the EVM is being used with lab equipment, separate cables can be connected to these main points via simple 2 pin header connectors.If the board is being connected to a processor based system, a single cable with all power & signals can be connected via a 10 pin header cable to this port. 2.1.4 TXD Input (JMP2 or TP1) The TXD (pin 1) of the transceiver, transmit data is routed to JMP2 and TP1. The signal path to the JMP2 header is pre-installed with a 0Ω series resistor, R10. 2.1.5 RXD Output (JMP2 or TP7) The RXD (pin 4) of the transceiver, receive data is routed to JMP2 and TP7. The signal path to the JMP2 header is pre-installed with a 0Ω series resistor, R13.

Pin 8 of the device is routed to JMP1, JMP2 and TP7. 2.1.7 MODE - JMP1 configurations (3 way jumper) If using separate I/O inputs JMP1 will be used to configure pin 8 to a pull up to VCC or pull down to GND configuration. For most devices when Pin 8 is pulled to GND the device will be in “normal” or high speed mode. R3 is pre-installed with 0Ω resistor to GND for this purpose. For most devices when Pin 8 is pulled to VCC the device will be in a silent or low power standby mode. Devices with slope control mode use the resistance to ground value to determine the slope of the driver output. R2 is left open for customers who want to install a resistance to ground and use slope mode. 2.1.8 JMP2 configuration Using header JMP2 which assumes all the digital I/O signals, VCC, GND are routed to an external system. Ensure that the MODE (JMP1) jumper settings are not conflicting with signals to JMP2. 2.1.9 TP3 configuration This connects directly to device pin 8. Ensure JMP1 configuration isn’t conflicting if TP3 is used as the input connection. 2.1.10 Pin 5 (JMP6, JMP2 or TP8) Pin 5 of the transceiver have various uses depending on the transceiver. Examples are VREF, SPLIT, VRXD, VIO, LBK, EN, AB and No Connect (NC). Pin 5 of the device is routed to JMP6, JMP2 and TP8. 2.1.11 Pin 5 – JMP6 configurations (4 way jumper) If using separate I/O inputs JMP6 will be used to configure pin 5 to: pull up to VCC, pull down to GND, VRXD / VIO supply input or VREF/SPLIT termination output. • VREF/SPLIT termination: If the device & application support split termination then JMP6 should be set to VCM (V Common Mode) to drive the VREF/SPLIT pin common mode stabilizing voltage output to the center tap of the split termination capacitor. These components will need to be installed on the EVM as outlined in the CAN bus termination section. • No Connection: If the device & application require no use of pin 5 then it may be left open. If the device has VREF or SPLIT pin but the application isn’t using the pin for split termination then a capacitor may be added on C6 to improve EMC performance. • 2nd Mode / Control Input: if the device & application use pin 5 as a second mode or control pin then JMP6 should be set to as either a pull up to VCC or pull down to GND as necessary. • I/O & RXD level shifting supply: if the device & application use with VIO or VRXD to level shift I/O pins on the transceiver then JMP6 may be set to VRXD which connects pin 5 of the device to VRXD pin on JMP2. Local buffering and bypass capacitor C6 should be installed. 2.1.12 JMP2 configuration Using header JMP2 assumes all the digital I/O signals, VCC, GND are routed to an external system. Ensure that Pin 5 (JMP6) jumper settings are not conflicting with signals to JMP2. For power supply VRXD the jumper needs to be set to route JMP2 supply input to the transceiver pin. 2.1.13 TP8 configuration This connects directly to device pin 5. Ensure JMP6 configuration isn’t conflicting if TP8 is used as an input connection. 6 CAN EVM User Guide Copyright © 2011, Texas Instruments Incorporated SLLU158 – December 2011 Submit Documentation Feedback 2 EVM Setup and Operation www.ti.com 2.2 Using CAN Bus Load, Termination and Protection Configurations The CAN EVM is populated with two 120Ω power resistors selectable via jumpers between CANH and CANL. By using one, the EVM may be used as a terminated end of a bus. For electrical measurements to represent the total loading of the bus, use both 120Ω resistors in parallel to give the standard 60Ω load for parametric measurement. The EVM also has footprints is split termination is needed for the application. The table below summarizes how to use these termination options. If split termination is used, care must be taken to match the resistors. The common mode filter frequency may be calculated by: fC = 1/(2πRC). Normally, the split capacitance is in the range of 4.7nF to 100nF. Keep in mind this is the common mode filter frequency, not a differential filter that will impact the differential CAN signal directly. Table 3.

Unless otherwise indicated, this EVM is not a finished electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end product. Your Sole Responsibility and Risk. You acknowledge, represent and agree that: 1. 2. 3. 4. You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes. You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected. Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate Assurance and Indemnity Agreement.
