2 MAX0A Shield EV Kit Evaluates: MAX0A Detailed Description of Hardware The MAX0A Shield is a fully assembled and tested circuit board for evaluating the MAX0A faultprotected high speed CAN transceiver (U) with ±V of fault protection. The Shield is designed to evaluate MAX0A alone or in a CAN system. The MAX0A Shield enables mbed or Arduino platform to communicate on a CAN bus. The MAX9 digital isolator is used as a level translator with a.v to.v supply range. Powering the Board The MAX0A Shield requires one power supply for V operation. The power supply can come from an external supply or the Arduino/Mbed microcontroller s V supply. To select the external supply, shunt the JU VDD pin to VDD_EXT pin option, - default position. To connect the Arduino/mbed V supply to VDD, shunt JU VDD pin to V, - position. Similarly, the V L supply is selected using JU. Shunt JU to - position to select the external supply from a range of.v to.v. Shunt JU to - position to select the Arduino/mbed V supply. Refer to Table for jumper settings. On-Board Termination A properly terminated CAN bus is terminated at each end with the characteristic impedance of the cable. For CAT or CAT cables, this is typically 0Ω on each end for a 0Ω load on the CAN driver. The MAX0A Shield features a selectable 0Ω load and a 0Ω-0Ω split termination circuit between the and driver outputs. The 0Ω-0Ω 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 0Ω (0Ω-0Ω) termination. The termination resistors on the MAX0A Shield should be changed to a 0Ω with optional footprint for a 00pF load, to simulate a complete system load during evaluation. and can also be left unloaded. TXD and RXD Configuration Digital channel assignments for TXD and RXD are selected via JU. It consists of three columns, and rows. The columns labeled TXD and RXD are connected to INA and OUTA pins on of the MAX9FASE+ (U), respectively. The middle column is the digital I/O pins, D0 to D. 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 shows the list of JU jumper options. DB9 Connector The MAX0A Shield has a DB9 connector to and (pins and, respectively). SD Card The MAX0A Shield has a SD card socket. The micro-sd card is connected to D0-D to interface with Arduino/mbed board through SPI. Maxim Integrated
