1. HARDWARE
1.1
The CDB5467U evaluation board provides a convenient means of evaluating the CS5467 power mea-
surement IC. The CDB5467U evaluation board operates from a single +5V power supply. The evaluation
board interfaces the CS5467 to a PC via a USB cable. To accomplish this, the board comes equipped
with a C8051F320 microcontroller and a USB interface. Additionally, the CDB5467U GUI software pro-
vides easy access to the internal registers of the CS5467. The software also provides a means to display
the performance in the time domain or frequency domain.
1.2
The board is partitioned into two main sections: analog and digital. The analog section consists of the
CS5467 and a precision voltage reference. The digital section consists of the C8051F320 microcontroller,
EEPROM, the hardware test switches, the reset circuitry, and the USB interface. The board also has a
user friendly power supply connection.
