EMC1102 SST Compliant Hardware Monitor with Two Temperature Channels Data Brief PRODUCT FEATURES Resistance Error Correction General Description Ideality Configuration The EMC1102 is a one-wire sensor that is capable of Beta Compensation monitoring up to two temperature zones for an Intel PC External Temperature Monitor platform containing an SST host. The two temperature 0.125C resolution zones consist of an internal temperature diode and an 1C Accuracy (50C to 70C) externally connected temperature diode. In cooperation Diode Fault Reporting with a host device, thermal management and fan control Internal Temperature Monitor can be performed. Communication takes place over a Range -40C to +125C one-wire SST based interface. The internal 11-bit delta- 0.125C resolution sigma ADC architecture provides superb linearity, high 2C Accuracy (40C to 70C) accuracy, and excellent noise immunity.
