EMC1103 SST Compliant Hardware Monitor with Three Temperature Channels PRODUCT FEATURES Data Brief General Description The EMC1103 is a one-wire sensor that is capable of monitoring up to three temperature zones for an Intel PC platform containing an SST host. The three temperature zones consist of an internal temperature diode and two externally connected temperature diodes. In cooperation with a host device, thermal management and fan control can be performed. Communication takes place over a one-wire SST based interface. The internal 11-bit deltasigma ADC architecture provides superb linearity, high accuracy, and excellent noise immunity. Applications — — — — 0.125°C resolution ±1°C Accuracy (50°C to 70°C) Diode Fault Reporting Second External Diode configured to read a discrete diode. Internal Temperature Monitor — Range -40°C to +125°C — 0.125°C resolution — ±2°C Accuracy (40°C to 70°C) Desktop PCs, Servers and Workstations Resistance Error Correction Ideality Configuration Beta Compensation Two External Temperature Monitors Supply — 3.0V to 3.6V Features Single Wire Interface (SST based) — — — — SST 1.0 compliant Fixed Address, Discoverable Device Nine programmable addresses Supports FCS Abort functionality not available in SST 0.9 compliant devices Simplified Block Diagram EMC1103 Switching Current Configuration Register Analog Mux and Anti-Alias Filter DP1 DN1 DP2 DN2 11-bit delta-sigma ADC External 2 Temp Register Digital Mux and Byte Interlock Internal Temp Register SST One-Wire Interface External 1 Temp Register ADD1 ADD0 Internal Temp Diode Status Register SMSC EMC1103 PRODUCT PREVIEW SST Revision 2.7 (07-15-08) SST Compliant Hardware Monitor with Three Temperature Channels ORDER NUMBER(S): PART NUMBER FEATURES PACKAGE EMC1103-AIZL-TR External Diode 1 configured to monitor 65nm CPU External Diode 2 configured to monitor 2N3904 10 pin MSOP Lead-Free ROHS Compliant External Diode 1 configured to monitor 2N3904 External Diode 2 configured to monitor 2N3904 10 pin MSOP Lead-Free ROHS Compliant EMC1103-1-AIZL-TR 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright © 2008 SMSC or its subsidiaries.
