ADM00768

The ADM00768 from Microchip is a MCP9904 remote temperature sensor evaluation board. The board provides the means to demonstrate all of the MCP9904 features and allows a user to view and modify registers. User may plot the temperature of the four temperature channels and set alert temperatures associated with those channels. LEDs indicating status information and test points are included to enable system voltages monitoring, using a voltmeter or an oscilloscope. The board requires only one universal serial bus (USB) connection to power the board. The USB to SMBus bridge regulates the +5V USB power to +3.3V used by the MCP9904 and other evaluation board circuitry. The user can perform the following operations using the Chip Manager such as viewing and changing register values, saving settings of all registers and allowing for quick configuration at a later time and graphing of any register.

• Resistance Error Correction verification using an on-board potentiometer
• USB to SMBus bridge for power and communications
