MAX13054A Shield Evaluates MAX13054A Detailed Description of Hardware The MAX13054A Shield is a fully assembled and tested circuit board for evaluating the MAX13054A faultprotected high speed CAN transceiver U1 with ±65V of fault protection. The Shield is designed to evaluate MAX13054A alone or in a CAN system. The MAX13054A Shield enables mbed or Arduino platform to communicate on a CAN bus. The MAX14850 digital isolator is used as a level translator with a 3V to 5.5V supply range. For logic levels below 3V, remove the R1 resistor and apply TXD directly on TXD_U1 test point. Powering the Board The MAX13054A Shield requires one power supply for 5V operation. The power supply can come from an external supply or the Arduino/Mbed microcontroller’s 5V supply. To select the external supply, shunt the JU1 VDD pin to VDD_EXT pin option, 2-3 default position. To connect the Arduino/mbed 5V supply to VDD, shunt JU1 VDD pin to 5V, 1-2 position. Similarly, the VL supply is selected using JU2. Shunt JU2 to 2-3 position to select the external supply from a range of 1.62V to 5.5V. Shunt JU2 to 1-2 position to select the Arduino/mbed 5V supply. Refer to Table 1 for jumper settings. On-Board Termination A properly terminated CAN bus is terminated at each end with the characteristic impedance of the cable. For CAT5 or CAT6 cables, this is typically 120Ω on each end for a 60Ω load on the CAN driver. The MAX13054A Shield features a selectable 60Ω load and a 60Ω-60Ω split termination circuit between the CANH and CANL driver outputs. The 60Ω-60Ω split termination has a footprint for a capacitor to reduce high frequency noise and common mode drift. If the board is evaluated in a system and is connected at the end of the cable, then select the 120Ω 60Ω-60Ω termination. The termination resistors on the MAX13054A Shield should be changed to a 60Ω with optional footprint for a 100pF load, to simulate a complete system load during evaluation. CANH and CANL can also be left unloaded. TXD and RXD Configuration Digital channel assignments for TXD and RXD are selected via JU8. It consists of three columns, and 14 rows. The columns labeled TXD and RXD are connected to INA1 and OUTA1 pins on of the MAX14850AEE+ U2 , respectively. The middle column is the digital I/O pins, D0 to D13. This provides flexibility for the user to select different resources on the microcontroller for transmitting and receiving signals to and from the CAN transceiver. Table 2 shows the list of JU8 jumper options. DB9 Connector The MAX13054A Shield has a DB9 connector to CANH and CANL pins 7 and 2, respectively . SD Card The MAX13054A Shield has a SD card socket. The micro-SD card is connected to D10-D13 to interface with Arduino/mbed board through SPI.

Detailed Description of Hardware

The MAX13054A Shield is a fully assembled and tested circuit board for evaluating the MAX13054A faultprotected high speed CAN transceiver U1 with ±65V of fault protection. The Shield is designed to evaluate MAX13054A alone or in a CAN system. The MAX13054A Shield enables mbed or Arduino platform to communicate on a CAN bus. The MAX14850 digital isolator is used as a level translator with a 3V to 5.5V supply range. For logic levels below 3V, remove the R1 resistor and apply TXD directly on TXD_U1 test point.

Powering the Board

The MAX13054A Shield requires one power supply for 5V operation. The power supply can come from an external supply or the Arduino/Mbed microcontroller’s 5V supply. To select the external supply, shunt the JU1 VDD pin to VDD_EXT pin option, 2-3 default position. To connect the Arduino/mbed 5V supply to VDD, shunt JU1 VDD pin to 5V, 1-2 position. Similarly, the VL supply is selected using JU2. Shunt JU2 to 2-3 position to select the external supply from a range of 1.62V to 5.5V. Shunt JU2 to 1-2 position to select the Arduino/mbed 5V supply. Refer to Table 1 for jumper settings.

On-Board Termination

A properly terminated CAN bus is terminated at each end with the characteristic impedance of the cable. For CAT5 or CAT6 cables, this is typically 120Ω on each end for a 60Ω load on the CAN driver. The MAX13054A Shield
features a selectable 60Ω load and a 60Ω-60Ω split termination circuit between the CANH and CANL driver outputs. The 60Ω-60Ω split termination has a footprint for a capacitor to reduce high frequency noise and common mode drift. If the board is evaluated in a system and is connected at the end of the cable, then select the 120Ω 60Ω-60Ω termination. The termination resistors on the MAX13054A Shield should be changed to a 60Ω with optional footprint for a 100pF load, to simulate a complete system load during evaluation. CANH and CANL can also be left unloaded.
