EMC1102-ACZL-TR

EMC1102 SST Compliant Hardware Monitor with Two Temperature Channels PRODUCT FEATURES Data Brief General Description „ The EMC1102 is a one-wire sensor that is capable of monitoring up to two temperature zones for an Intel PC platform containing an SST host. The two temperature zones consist of an internal temperature diode and an externally connected temperature diode. 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. „ „ Resistance Error Correction Ideality Configuration Beta Compensation External Temperature Monitor — 0.125°C resolution — ±1°C Accuracy (50°C to 70°C) — Diode Fault Reporting „ Internal Temperature Monitor — Range -40°C to +125°C — 0.125°C resolution — ±2°C Accuracy (40°C to 70°C) „ Supply — 3.0V to 3.6V Applications „ „ Desktop PCs, Servers and Workstations 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 EMC1102 Switching Current Configuration Register Analog Mux and Anti-Alias Filter DP DN 11-bit delta-sigma ADC Internal Temp Register Digital Mux and Byte Interlock ADD1 SST One-Wire Interface External Temp Register ADD0 Internal Temp Diode Status Register SMSC EMC1102 PRODUCT PREVIEW SST Revision 2.71 (10-21-08) SST Compliant Hardware Monitor with Two Temperature Channels ORDER NUMBER(S): PART NUMBER FEATURES PACKAGE EMC1102-ACZL-TR External Diode configured to monitor 65nm CPU 8 pin MSOP Lead-Free, ROHS Compliant 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright © 2008 SMSC or its subsidiaries.
