... A power down mode extends battery life in portable applications. The internal 11-bit sigma delta temperature-to-digital converter provides superb linearity, high accuracy and excellent noise immunity. The EMC1212 is designed to operate with 65nm or 90nm PNP substrate transistor used as a thermal diode with the collector connected to ground. Switching ...

... BudgetBus Protocol The EMC1212 communicates with a host controller, such as the SMSC KBC1100, through the proprietary single wire SMSC BudgetBus™ Sensor Interface known as BBUS. The BBUS is a single wire serial communication protocol between the computer host and its peripheral devices. Please refer to the BBUS Specification for detailed information about the modes of operation ...

... Active Mode: The host initiates active mode by enabling a weak pull up on the BBUS. In this mode, the EMC1212 continuously converts 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 ...

... Because the beta compensation circuit is designed to work with PNP substrate transistors, the EMC1212 should not be used with diode-connected transistors (such as the 2N3904) or CPUs that implement the thermal diode as a two-terminal diode. The beta compensation circuit is not present in the EMC1202 availabe from SMSC, and this device is an excellent companion to AMD CPUs ...
