Functional Description

2.2 Serial Bus Interface
The Serial Bus control lines consists of the SDA(serial data),
SCL (serial clock) and A0-A1 (address) pins. The LM80 can
only operate as a slave. The SCL line only controls the serial
interface, all other clock functions within LM80 such as the
ADC and fan counters are done with a separate asynchro-
nous internal clock.
When using the Serial Bus Interface a write will always con-
sist of the LM80 Serial Bus Interface Address byte, followed
by the Internal Address Register byte, then the data byte.
There are two cases for a read:
1.
If the Internal Address Register is known to be at the de-
sired Address, simply read the LM80 with the Serial Bus
Interface Address byte, followed by the data byte read
from the LM80.
2.
If the Internal Address Register value is unknown, write
to the LM80 with the Serial Bus Interface Address byte,
followed by the Internal Address Register byte. Then re-
start the Serial Communication with a Read consisting of
the Serial Bus Interface Address byte, followed by the
data byte read from the LM80.
The default power on Serial Bus address for the LM80 is:
0101(A2)(A1)(A0) binary, where A0-A2 reflect the state of
the pins defined by the same names.
All of these communications are depicted in the Serial Bus
Interface Timing Diagrams as shown in Figure 5
