... Datasheet Chapter 3 System Management Bus Interface Protocol A host controller, such as an SMSC I/O controller, communicates with the EMC1002 via the two wire serial interface named SMBus. The SMBus interface is used to read and write registers in the EMC1002, which is a slave-only device. A detailed timing diagram is shown in ...

... The EMC1002 supports stretching of the SMCLK signal by other devices on the SMBus but will not perform this operation itself. The EMC1002 has an SMBus timeout feature. Bit 7 of the Consecutive Alert register enables this function when set to 1 (the default setting is 0) ...

... Run Mode: In this mode, the EMC1002 continuously converts temperature data and updates its registers. The rate of temperature conversion is configured as shown in Register," on page Standby Mode: In this mode, the EMC1002 is placed in standby to conserve power as described in 4.7, "Standby Mode," on page 4.1 Temperature Monitors Thermal diode temperature measurements are based on the change in forward bias voltage (Δ ...

... Remote Sensors Connected by Cables When connecting remote diodes with a cable (instead of traces on the PCB) use shielded twisted pair cable. The shield should be attached to ground near the EMC1002, and should be left unconnected at the sensor end. Belden 8451 cable is a good choice for this application. ...
