Page 8: Hardware Description
EMC2106 The EMC2106 is an SMBus temperature sensor with 1 internal and 4 external sensor in an 28 pin QFN package. Communications with the EMC2106 sensor is via the SMBus. USB to SMBus Bridge The USB to SMBus bridge is based on an 8051 microcontroller with integrated USB and SMBus interfaces as well as internal flash and RAM. -

EMC2106 via Chipman. If a 5V 4-wire fan is available, connectors J1 and J2 can be used to evaluate the EMC2106’s ability to drive and control these types of fans. If PWM1 is to control the 4-wire fan, the appropriate register in Chipman should be set. - Page 10 The remote diode on board the EMC2106 EVB has a heater and an optional inline series resistance adjustment. Checking the REC feature of the EMC2106 is accomplished by removing the jumper on JP9. This adds 100 ohms of series resistance to the DN line of the diode connection. To return to 0 ohm series resistance, replace the jumper on JP9.
- Page 11 2 GPIO6 switch 3 The EMC2106 EVB also allows testing of all the muxed pins as well as voltage input adjustments for the TRIP_SET and VIN4 functions. Table 3.5 summarizes all of the jumpers that appear on page 2 of the schematic SCH-7106.

ChipMan application. then select Options -> Plot Register Data from the menubar. Once the graph appears, select Control -> Start to begin plotting data. The history plot continuously updates the register data reported by the EMC2106. Figure 4.1below is a typical Temperature History with the external diode starting at room temp and then being heated using the HEATER jumper (JP10).
