... Introduction The CDB5463U evaluation board provides a convenient means of evaluating the CS5463 power mea- surement IC. The CDB5463U evaluation board operates from a single +5V power supply. The evaluation board interfaces the CS5463 via a USB cable. To accomplish this, the board comes equipped with a C8051F320 microcontroller and a USB interface. Additionally, the CDB5463U GUI software pro- vides easy access to the internal registers of the CS5463 ...

... Analog Section The CDB5463U evaluation board provides screw-type terminals (J23, J27) to connect input signals to the voltage and current channels. The screw terminals are labels as VIN+, VIN1-, IIN+, and IIN-. A simple R-C network at each channel input provides a simple anti-alias filter. The evaluation board provides three voltage reference options for VREFIN to the CS5463. The three volt- age reference options include: VREFOUT from CS5463, the on-board +2 ...

... The microcontroller interfaces the SPI of CS5463 with the USB connection to the PC, enabling the GUI software to access all the CS5463 registers and functions. Interface header, J40, is provided to allow the CDB5463U to be connected to an external energy registration device or an external microcontroller. To connect the CS5463 to an external microcontroller, R57, R58, R59, R60, R61, and R62 must be removed from the board ...

... HEX: field changing any of the values below the HEX: field to the desired set- tings. Although the CDB5463U software allows the user to modify any of the bits in the Config register, changing certain bits may cause the software and board to behave erratically. For the evaluation system to function properly, the Interrupt Output field should be set to the default Active Low ...
