EMC1203/EMC1204
Triple/Quad Single-Wire Temp Sensor in MSOP-8 Using SMSC BudgetBus™ Sensor Interface
Note: These products are companions to the KBC1102 or KBC1122 and are intended to be used in conjunction with them.
General Description
The EMC1203 and EMC1204 are temperature sensors that communicate with a host over a single-wire SMSC BudgetBus™ Sensor Interface. The EMC1203 has an
internal temperature sensor and monitors up to two remote diodes. An additional remote diode is added with the EMC1204 for a total of three remote zones, and both devices are in a small MSOP-8 package. When used in combination with an SMSC Super I/O host, such as a keyboard controller, a complete thermal management
system is created. A power down mode preserves battery life in portable applications. The internal 11-bit sigma delta temperature-to-digital converter provides superb linearity, high accuracy and excellent noise immunity.
