EMC1046/EMC1047 1°C Multiple Temperature Sensor with Beta Compensation and Hottest of Thermal Zones PRODUCT FEATURES Data Brief General Description Features The EMC1046/EMC1047 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to CPU diodes requiring the BJT or transistor model) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Each device provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The EMC1046/EMC1047 monitors up to seven temperature channels (up to six external and one internal). Applications — — — — ±1°C Accuracy (60°C < TDIODE < 100°C) 0.125°C Resolution Supports up to 2.2nF filter capacitor Anti-parallel diodes for extra diode support and compact design Internal Temperature Monitor 3.3V Supply Voltage Available in a 10-pin TSSOP lead-free RoHS Compliant package — ±2°C accuracy Notebook Computers Desktop Computers Industrial Embedded Applications Designed to support 45nm, 65nm, and 90nm CPU diodes Supports diodes requiring the BJT or transistor model Resistance Error Correction (up to 100 Ohms) Up to six External Temperature Monitors Block Diagram DP1 / DN6* DN1 / DP6* DP2 / DN3 DN2 / DP3 DN4 / DP5 SMCLK External Temp Diodes SMDATA Analog Mux DP4 / DN5 Antiparallel diode 11 bit Σ Δ ADC Temp Registers SMBus Slave Protocol Hottest of Comparison Internal Temp Diode * denotes EMC1047 only SMSC EMC1046/EMC1047 PRODUCT PREVIEW Revision 0.69 (06-29-09) 1°C Multiple Temperature Sensor with Beta Compensation and Hottest of Thermal Zones ORDER NUMBERS: ORDERING NUMBER PACKAGE FEATURES DIODE MODES SUPPORTED SMBUS ADDRESS EMC1046-1-AIZL-TR 10-pin TSSOP (Lead-Free RoHS Compliant) Up to 5 external diodes. “Hottest Of” temperature comparison Intel CPU, 3904, AMD with setup 1001_100(r/w) EMC1046-6-AIZL-TR 10-pin TSSOP (Lead-Free RoHS Compliant) Up to 5 external diodes. “Hottest Of” temperature comparison Intel CPU, 3904, AMD with setup 1001_101(r/w) EMC1047-1-AIZL-TR 10-pin TSSOP (Lead-Free RoHS Compliant) Up to 6 external diodes. “Hottest Of” temperature comparison Intel CPU, 3904, AMD with setup 1001_100(r/w) EMC1047-2-AIZL-TR 10-pin TSSOP (Lead-Free RoHS Compliant) Up to 6 external diodes. “Hottest Of” temperature comparison Intel CPU, 3904, AMD with setup 1001_000(r/w) Reel Size is 4,000 pieces 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright © 2009 SMSC or its subsidiaries.
