1 / 45 page  SMSC EMC1423/EMC1424 DATASHEET Revision 1.16 (03-15-07) Datasheet PRODUCT FEATURES EMC1423/EMC1424 1°C Temperature Sensor with Hardware Thermal Shutdown GENERAL DESCRIPTION The EMC1423 and EMC1424 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support 90nm and 65nm CPU diodes) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Additionally, the EMC1423 and EMC1424 provide a hardware programmable system shutdown feature that is programmed at part power-up via two pull-up resistor values and that cannot be masked or corrupted through the SMBus. Each device provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The EMC1423 monitors three temperature channels (two external and one internal). The EMC1424 monitors four temperature channels (three external and one internal). Resistance Error Correction automatically eliminates the temperature error caused by series resistance allowing greater flexibility in routing thermal diodes. Beta Compensation eliminates temperature errors caused by low, variable beta transistors common in today's fine geometry processors. The automatic beta detection feature monitors each external diode/transistor and determines the optimum sensor settings for accurate temperature measurements regardless of processor technology. This frees the user from providing unique sensor configurations for each temperature monitoring application. These advanced features plus ±1°C measurement accuracy provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.
