Instructions for TJA1020T/CM118

1. Power Supply Connection:

   • Connect the Vcc pin to a stable power supply within the operating range of 3.0V to 5.5V.
   • Ensure the GND pin is connected to the system ground.

2. Enable Pin (EN):

   • The EN pin controls the active or standby state of the device.
   • Set EN high (Vcc) to enable the transceiver.
   • Set EN low (GND) to put the device into low-power standby mode.

3. Data Transmission:

   • Use the TXD and RXD pins for data transmission and reception.
   • Ensure the baud rate does not exceed 1 Mbps for reliable communication.

4. Termination Resistors:

   • For optimal performance, connect a 120Ω termination resistor between CAN_H and CAN_L at both ends of the bus.

5. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 125°C to ensure reliability and longevity.

6. Electrostatic Discharge (ESD) Protection:

   • Handle the device with appropriate ESD precautions to prevent damage.

7. Mounting and Layout:

   • Follow recommended PCB layout guidelines to minimize noise and interference.

8. Signal Integrity:

   • Keep signal traces as short as possible to maintain signal integrity, especially for high-speed applications.
