XOUT, XIN - The output and input of an inverting amplifier. Oscillation occurs when connected to
a crystal, providing an on-chip system clock. Alternatively, an external clock can be supplied to
the XIN pin to provide the system clock for the device.
CPUCLK - Output of on-chip oscillator which can drive one standard CMOS load.
SCLK - A Schmitt Trigger input pin. Clocks data from the SDI pin into the receive buffer and out of
the transmit buffer onto the SDO pin when CS is low.
SDO -Serial port data output pin.SDO is forced into a high impedance state when CS is high.
CS - Low, activates the serial port interface.
MODE - High, enables the “auto-boot” mode. The mode pin is pulled low by an internal resistor.
E3 - Active low pulses with an output frequency proportional to the active power. Used to assist
in system calibration.
RESET - A Schmitt Trigger input pin. Low activates Reset, all internal registers (some of which
drive output pins) are set to their default states.

INT - Low, indicates that an enabled event has occurred.
E1, E2 - Active low pulses with an output frequency proportional to the active power. Indicates if
the measured energy is negative.
SDI - Serial port data input pin. Data will be input at a rate determined by SCLK.
VIN+, VIN- - Differential analog input pins for the voltage channel.
IIN+, IIN- - Differential analog input pins for the current channel.
VREFOUT - The on-chip voltage reference output. The voltage reference has a nominal magni-
tude of 2.5 V and is referenced to the AGND pin on the converter.
VREFIN - The input to this pin establishes the voltage reference for the on-chip modulator.
VD + - The positive digital supply.
DGND - Digital Ground.
VA+ - The positive analog supply.
AGND - Analog ground.
PFMON - The power fail monitor pin monitors the analog supply. If PFMON’s voltage threshold is
not met, a Low-Supply Detect (LSD) bit is set in the status register.
