controller area networking bus; CAN bus

network designed for use in automotives, which:
a) uses a single terminated twisted pair cable;
b) is multi master;
c) uses a maximum signal frequency used is 1 Mbit/sec;
d) has a typical length of 40 M at 1 Mbit/sec up to 10 KM at 5 Kbits/sec;
e) has high reliability with extensive error checking;
f) has a typical maximum achieveable data rate of 40 KBytes/sec;
g) has a maximum latency of high priority message <120 μsec at 1 Mbit/sec
NOTE 1 to entry: CAN is unusual in that the entities on the network, called nodes, are not given specific addresses.
Instead, it is the messages themselves that have an identifier which also determines the messages’ priority. For this reason, there is no theoretical limit to the number of nodes, although in practice it is ~64.
