The Waveshare CAN Board SN65HVD230 features an accessory onboard CAN transceiver, which is pinout compatible with PCA82C250. It is powered from 3.3 V and features ESD protection.

The SN65HVD230 CAN Board is ideal to connect microcontrollers to the CAN network. Designed for operation in especially-harsh environments, it features cross-wire protection, loss-of-ground and overvoltage protection, overtemperature protection, as well as wide common-mode range.

The transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications. It operates over a -2 to 7 V common-mode range on the bus, and it can withstand common-mode transients of ±25 V.

The circuit of the SN65HVD230 enters a low-current standby mode during which the driver is switched off and the receiver remains active if a high logic level is applied to pin 8. The DSP controller reverses this low-current standby mode when a dominant state (bus differential voltage > 900 mV typical) occurs on the bus.

The unique difference between the SN65HVD230 and the SN65HVD231 is that both the driver and the receiver are switched off in the SN65HVD231 when a high logic level is applied to pin 8 and remain in this sleep mode until the circuit is reactivated by a low logic level on pin 8.
