... General Description The EMC1203 and EMC1204 are temperature sensors that communicate with a host over a single-wire SMSC BudgetBus™ Sensor Interface. The EMC1203 has an internal temperature sensor and monitors up to two remote diodes. An additional remote diode is added with the EMC1204 for a total of three remote zones, and both devices are in a small MSOP-8 package ...

... EMC1203 Temperature Monitoring The EMC1203, incorporates one internal diode and can monitor two additional temperature zones with two external diodes.An internal analog multiplexer switches between the internal and external diodes. Total conversion time for one internal and two external temperature readings is about 60ms. The external diodes can be either a CPU substrate diode or a discrete diode connected transistor like the 2N3904 or 2N3906 ...

... Active Mode: The host initiates active mode by enabling a weak pull up on the BBUS. In this mode, the EMC1203 and EMC1204 continuously convert temperature data. During the time that the device is actively converting a temperature, the BBUS is in tri-state mode, and the Host places a weak pull-up on the bus to prevent it from floating ...
