1. HARDWARE
1.1 Introduction
The CDB5480U evaluation board provides a convenient means of evaluating the CS5480 energy
measurement IC. The CDB5480U evaluation board operates from a single USB or 5V power supply. An
optional 3.3V power supply input is available for powering the CS5480 directly. The evaluation board
interfaces the CS5480 to a PC via a USB cable. To accomplish this, the board comes equipped with a
C8051F342 microcontroller and a USB interface. Additionally, the CDB5480U GUI software provides
easy access to the internal registers of the CS5480. The software also provides a means to display the
on-chip ADC performance in the time domain or frequency domain.
1.2 Evaluation Board Overview
The board is partitioned into two main sections: analog and digital. The analog section consists of the
CS5480, passive anti-aliasing filters, and a high-voltage section with attenuation resistor networks. The
digital section consists of the C8051F342 microcontroller, LCD, the test switches, the reset circuitry, and
the USB interface. The board also has a user-friendly power supply connection. The assembly information
and default configurations for jumpers are shown below.
