EMC1072 1°C Temperature Sensor with Selectable Address PRODUCT FEATURES Data Brief General Description Features The EMC1072 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor with pin selectable SMBus address. The device provides ±1° accuracy (max) for external diode temperatures and ±2°C accuracy (max) for the internal diode temperature. The EMC1072 monitors two temperature channels (one external and one internal). Pin Compatible with ADM1032, MAX6649, and LM99 External Temperature Monitors — ±0.25°C typ accuracy (20°C < TDIODE < 110°C) — 0.125°C resolution — Supports 2N3904 and AMD diodes Internal Temperature Monitor 3.3V Supply Voltage SMBus 2.0 Compliant — ±0.25°C typ accuracy (-5°C < TA < 100°C) Applications — Programmable SMBus address Notebook Computers Desktop Computers Industrial Embedded applications Programmable Temperature Limits for ALERT and THERM Available in Small 8-pin MSOP Lead-free RoHS Compliant Package Block Diagram VDD EMC1072 Conversion Rate Register DP Internal Temperature Register DN Digital Mux ΔΣ ADC External Temperature Register(s) Limit Comparator Analog Mux Digital Mux High Limit Registers THERM Limit Register SMBus Interface Low Limit Registers Switching Current SMCLK SMDATA THERM Hysteresis Register Configuration Register Internal Temp Diode Status Registers Interupt Masking ALERT SMBus Address Decode THERM/ADDR GND SMSC EMC1072 PRODUCT PREVIEW Revision 1.39 (10-11-10) 1°C Temperature Sensor with Selectable Address Order Number(s): EMC1072-1-ACZL-TR for 8-pin, MSOP Lead-Free RoHS Compliant package EMC1072-A-ACZL-TR for 8-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.
