... General Description The MIC281 is a digital thermal sensor capable of measuring the temperature of a remote PN junction optimized for applications favoring low cost and small size. The remote junction may be an inexpensive commodity transistor, e.g., 2N3906 embedded thermal diode such as found in Intel Pentium* II/III/IV CPUs, AMD Athlon* CPUs, and Xilinx Virtex* FPGAs ...

... The SMBus Read_Byte operation is a composite write and read operation: the host first sends the device’s slave address followed by the command byte write operation. A new start bit must then be sent to the MIC281, followed by a repeat of the MIC281 Slave Address DATA ...

... Slave Address The MIC281 will only respond to its own unique slave ad- dress. A match between the MIC281’s address and the address specified in the serial bit stream must be made to initiate communication. The MIC281’s slave address is fixed at the time of manufacture. Eight different slave addresses are available as determined by the part number ...

... Filter Capacitor Selection It is usually desirable to employ a filter capacitor between the T1 and GND pins of the MIC281. The use of this capacitor is recommended in environments with a lot of high frequency noise (such as digital switching noise long traces or wires are used to connect to the remote diode ...

... Layout Considerations The following guidelines should be kept in mind when design- ing and laying out circuits using the MIC281: 1. Place the MIC281 as close to the remote diode as possible, while taking care to avoid severe noise sources such as high frequency power transformers, CRTs, memory and data busses, etc ...
