1 / 19 page  SMSC EMC1023 DATASHEET Revision 1.2 (04-15-05) Datasheet EMC1023 1°C Triple Temperature Sensor with Resistance Error Correction General Description The EMC1023 is a System Management Bus (SMBus) temperature sensor that is capable of monitoring three temperature zones. Four unique part numbers can be ordered, each with a different SMBus Address. The three temperature zones consist of two external diodes and one internal monitor. Extended features include resistance error correction and ideality factor configuration eliminating both major sources of temperature measurement error.1 The 11-bit delta-sigma temperature-to-digital converter provides superb linearity, excellent noise immunity and repeatable temperature readings. An extended temperature format may be selected for compatibility with a broad range of CPUs. Selectable conversion rates and standby mode support low-power operation. Features ■ Resistance Error Correction ■ Ideality Factor Configuration ■ Accepts 2200pF cap for noise suppression ■ Remote Thermal Zones — ±1°C Accuracy (40°C to 80°C) — 0.125 °C resolution ■ Internal Thermal Zone — ±3°C Accuracy (0°C to 85°C) — 0.125 °C resolution ■ Low Power; 3.0V to 3.6V Supply ■ Four Unique SMBus Addresses Available ■ Programmable Conversion Rate ■ MSOP-8 3x3mm Package; Green, Lead-Free Package also available. Applications ■ Desktop and Notebook Computers ■ Thermostats ■ Smart batteries ■ Industrial/Automotive 1.Patents pending.
