... Alternately, the External Diode 2 channel can be configured to measure a standard thermal diode (such as a 2N3904) with Resistive Error Correction active. An added feature to the EMC1063 is a function that automatically compares the two external temperature zones and reports the hotter of the two temperatures. ...

... System Management Bus Interface Protocol A host controller, such as an SMSC I/O controller, communicates with the EMC1063 via the two wire serial interface named SMBus. The SMBus interface is used to read and write registers in the EMC1063, which is a slave-only device. A detailed timing diagram is shown in ...

Page 10

... Attempting to communicate with the EMC1063 SMBus interface with an invalid slave address or invalid protocol results in no response from the device and does not affect its register contents. The EMC1063 supports stretching of the SMCLK signal by other devices on the SMBus but will not perform this operation itself ...

Page 11

... The average power dissipation will depend on the conversion rate. When the EMC1063 is not actively converting a channel, it goes into a lower power wait state. Standby Mode (power-up default this mode, the EMC1063 is put into a low power state. In the standby mode, temperature monitoring is disabled. The device will still respond to SMBus commands ...

... HOTTER bit is cleared (set to ‘0’), and the results of the two remote zones are stored in their respective registers. 3.3.1 Conversion Rates The EMC1063 may be configured for different conversion rates based on the system requirements. The available rates are 1 full set of conversions per second to 16 full sets of conversions per second. The conversion rate is configured as described in shown in Table 4 ...

... The negative terminal for the remote temperature diode, DN, is internally biased with a forward diode voltage referenced to ground. The External Diode 2 channel in the EMC1063 is compatible with a broad range of thermal diode, including those found in AMD processors, that may be connected as shown in to ...

... Resistance Error Correction (REC) Resistance error correction is an optional feature in the EMC1063 that eliminates the need to characterize and compensate for series resistance in the External Diode 2 lines. The EMC1063 corrects for as much as 100 ohms of series resistance. When using a temperature sensor that does not include resistance error correction, voltage developed across the parasitic resistance in the external diode path produces an error in the reported temperature. The error introduced by this resistance is approximately +0.7° ...

... Ideality Factor should not be adjusted. Beta Compensation automatically corrects for most ideality errors. 3.8 Diode Faults The EMC1063 detects a fault if the DP pin is left floating or is shorted to VDD. In the case of a diode fault, the corresponding status bit will be set and the output data will be set at 400h. SMSC EMC1063 Section 4 ...

... Any reads to undefined registers will return 00h. Writes to undefined registers will not have an effect. The EMC1063 uses an interlock mechanism that will update the Low byte of a particular monitor when the High Byte is read. This prevents changes in register content when the ADC updates between successive reads ...

Bit 3 - MAX_RES - controls the external diode conversion time during dynamic averaging. Although the dynamic averaging may be used to increase the ADC resolution, only 11 bits of data are available in the temperature registers. ‘ ...
