Operational Guidelines
CAN EVB board allows easy evaluation of CAN transceivers in SOIC8 packages. It
provides connection to all the device’s pins as well as positions for all the
necessary CAN bus external components.
Configurations and assembly options are listed in Table 1. For more
information please check datasheet of the assembled CAN transceiver.
Table 1. ASSEMBLY OPTIONS AND CONFIGURATIONS
Component | Default | Function |
---|---|---|
Rth, Rtl, Cst | 2x 62 R, 4.7 nF | CAN bus termination |
ESD | none | Position for optional NUP2105 ESD protection |
Cesdh, Cesdl | 47 pF | ESD capacitors. Should be selected per application needs |
and ESD used
Rvcc, Rvio| 0 R| Connection of on-board LDOs to VCC and VIO. If removed,
external supplies can be used.
