SN65HVD230D Alternatives
The SN65HVD230D has several alternatives within the Texas Instruments transceiver lineup, including the SN65HVD230DR, SN65HVD72DR, SN65HVD78DR, and SN65HVD75DR. These devices share similar specifications, such as compatibility with ISO 11898-2 CAN standards and support for data rates up to 1 Mbps.
How to Use SN65HVD230D?
First, connect the power supply: Ensure that the Vcc pin (pin 3) is connected to a 3.3V power source, and the GND pin (pin 2) is connected to the ground.
Next, set the enable or standby mode: Connect the RS pin (pin 8) to control the mode of operation. To enable high-speed mode, connect RS to ground. If you need low-power standby mode, apply a high signal to RS.
Then, link the CAN bus lines: Connect the CANH (pin 7) and CANL (pin 6) to the corresponding CAN bus lines. These are the high and low differential lines that enable communication over the CAN network.
Afterward, manage the reference voltage: The Vref (pin 5) provides a reference voltage (typically 0.5 * Vcc) and can be used if required for additional circuitry, though it is optional in many designs.
Finally, connect the digital interface: The R pin (pin 4) and D pin (pin 1) are used to receive and transmit data. Connect the R pin to the microcontroller's RX input and the D pin to the microcontroller's TX output.
