EMC1046/EMC1047 1C Multiple Temperature Sensor with Beta Compensation and Hottest of Thermal Zones Datasheet PRODUCT FEATURES General Description Features Designed to support 45nm, 65nm, and 90nm CPU The EMC1046/EMC1047are high accuracy, low cost, diodes System Management Bus (SMBus) temperature sensors. Advanced features such as Resistance Error Supports diodes requiring the BJT or transistor model Correction (REC), Beta Compensation (to CPU diodes Resistance Error Correction (up to 100 Ohms) requiring the BJT or transistor model) and automatic Up to six External Temperature Monitors diode type detection combine to provide a robust 1C Accuracy (60C < T < 100C) DIODE solution for complex environmental monitoring 0.125C Resolution applications. Supports up to 2.2nF filter capacitor Each device provides 1 accuracy for external diode Anti-parallel diodes for extra diode support and temperatures and 2C accuracy for the internal diode compact design temperature. The EMC1046/EMC1047 monitor up to Internal Temperature Monitor seven temperature channels (up to six external and one 2C accuracy internal). 3.3V Supply Voltage Applications Available in a 10-pin TSSOP lead-free RoHS Notebook Computers Compliant package Desktop Computers Industrial Embedded Applications Block Diagram DP1 / DN6* SMCLK DN1 / DP6* External SMDATA DP2 / DN3 Temp DN2 / DP3 Diodes SMBus 11 bit DN4 / DP5 Temp Registers Slave ADC Analog DP4 / DN5 Protocol Mux Anti- Hottest of Comparison parallel diode Internal Temp Diode * denotes EMC1047 only SMSC EMC1046/EMC1047 DATASHEET Revision 0.69 (06-29-09) 1C Multiple Temperature Sensor with Beta Compensation and Hottest of Thermal Zones Datasheet ORDER NUMBERS: DIODE MODES SMBUS ORDERING NUMBER PACKAGE FEATURES SUPPORTED ADDRESS EMC1046-1-AIZL-TR 10-pin TSSOP Up to 5 external diodes.
