| USB 3.0/3.1 Gen 1 | 2 m (6.6 ft) | 5 m (16.4 ft) |
| USB 3.1 Gen 2 | 1 m (3.3 ft) | 1 m (3.3 ft) |
Is a bus a single wire?
Up to 32 nodes per network are allowed. The main application area of this physical layer is in comfort electronics networks in motor vehicles. An unshielded single wire is defined as the bus medium. A linear bus topology structure is not necessary.
Is 1-Wire the same as i2c?
1-Wire is similar in concept to I²C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. A network of 1-Wire devices with an associated master device is called a MicroLAN.
What is electronic bus?
(1) A bus is a network topology or circuit arrangement in which all devices are attached to a line directly and all signals pass through each of the devices. Each device has a unique identity and can recognize those signals intended for it.
How many wires does a bus have?
CAN bus uses two dedicated wires for communication. The wires are called CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V.
What is the longest USB?
The limit for USB 1.0/1.1 cable length is 3 meters (about 9 feet and 10 inches) and the maximum total length should not exceed 18 meters (about 59 feet).
What is the maximum length of USB cable?
The USB 1.1 standard specifies that a standard cable can have a maximum length of 5 meters (16 ft 5 in) with devices operating at full speed (12 Mbit/s), and a maximum length of 3 meters (9 ft 10 in) with devices operating at low speed (1.5 Mbit/s).
How do I drive a 1-wire bus?
A short 1-wire bus can be driven from a single digital I/O pin on a microcontroller. A UART can also be used. Specific 1-Wire driver and bridge chips are available. USB “bridge” chips are also available. Bridge chips are particularly useful to drive long (greater than 100 m) cables.
What is the speed of a 1-wire data bus?
The data wire is high when idle, and so it can also power a limited number of slave devices. Data rates of 16.3 kbit/s can be achieved. There is also an overdrive mode that speeds up the communication by a factor of 10. A short 1-Wire bus can be driven from a single digital I/O pin on a microcontroller.
What are the limitations of a USB port?
As with all standards, USB possesses multiple limitations to its design: USB cables are limited in length, as the standard was intended for peripherals on the same table-top, not between rooms or buildings. However, a USB port can be connected to a gateway that accesses distant devices.
