EMC1073 / EMC1074 Multiple Channel 1°C Temperature Sensor with Selectable Address PRODUCT FEATURES Data Brief General Description Features The EMC1073 and EMC1074 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors with pin selectable SMBus addresses. — — — — Each device provides ±1° accuracy (max) for external diode temperatures and ±2°C accuracy (max) for the internal diode temperature. The EMC1073 monitors three temperature channels (two external and one internal). The EMC1074 monitors four temperature channels (three external and one internal). Internal Temperature Monitor 3.3V Supply Voltage SMBus 2.0 Compliant — ±0.25°C typ accuracy (-5°C < TA < 100°C) — Programmable SMBus address Applications ±0.25°C typ accuracy (20°C < TDIODE < 110°C) 0.125°C resolution Supports 2N3904 and AMD diodes Anti-parallel diodes for extra diode support (EMC1074) External Temperature Monitors Notebook Computers Desktop Computers Industrial Embedded applications Programmable Temperature Limits for ALERT and THERM Available in Small 10-pin MSOP Lead-free RoHS Compliant Package Block Diagram VDD EMC1073 / EMC1074 Conversion Rate Register Switching Current ΔΣ ADC DN2 / DP3 Internal Temperature Register Digital Mux Analog Mux Anti-parallel diodes External Temperature Register(s) Digital Mux DN1 DP2 / DN3 Limit Comparator High Limit Registers THERM Limit Register SMBus Interface Low Limit Registers DP1 SMCLK SMDATA THERM Hysteresis Register Configuration Register Internal Temp Diode Status Registers Interupt Masking ALERT SMBus Address Decode THERM/ADDR SMSC EMC1073 / EMC1074 PRODUCT PREVIEW Revision 1.39 (10-11-10) Multiple Channel 1°C Temperature Sensor with Selectable Address Order Number(s): EMC1073-1-AIZL-TR for 10-pin, MSOP Lead-Free RoHS Compliant Package EMC1073-A-AIZL-TR for 10-pin, MSOP Lead-Free RoHS Compliant Package EMC1074-1-AIZL-TR for 10-pin, MSOP Lead-Free RoHS Compliant Package EMC1074-A-AIZL-TR for 10-pin, MSOP Lead-Free RoHS Compliant Package Reel size is 4,000 pieces This product meets the halogen maximum concentration values per IEC61249-2-21 For RoHS compliance and environmental information, please visit www.smsc.com/rohs 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright © 2010 SMSC or its subsidiaries.
