The ADT7488A is a simple digital temperature sensor for use in PC applications with Simple Serial Transport (SST) interface. It can monitor its own temperature as well as the temperature of two remote sensor diodes. It also measures the processor core voltage, VCCP; a 2.5 V supply voltage; and its own supply voltage, VCC. The ADT7488A is controlled by an SST single bidirectional data line. This device is a fixed-address SST client where the target address is chosen by the state of the address pin, ADD.
