EVALUATION BOARD HARDWARE
OVERVIEW
The ADE7953 evaluation kit includes two boards that should be
used together to evaluate the silicon. The smaller board, named
ADE IO INTERFACE BOARD Z (the interface board), consists
of an NXP LPC2368FBD100 microcontroller that handles all
communications from the PC to the ADE7953 (see Figure 1).
The larger board, named EVAL-ADE7953EBZ (the evaluation
board), includes the ADE7953 energy metering IC, associated
filtering, and isolation to allow high voltage inputs to be used
(see Figure 2). The two boards should be connected together
using the 25-pin connector included in the evaluation kit. The
connector is labeled P2 on the interface board and P7 on the
evaluation board.
Full schematics of the ADE7953 evaluation board and interface
board are provided in the Evaluation Board Schematics section
and the Interface Board Schematics section.

POWERING UP THE EVALUATION BOARD
The ADE7953 interface board receives power via the USB
cable that is connected to the PC. No additional power source
is required for the interface board.
The ADE7953 evaluation board requires a 3.3 V power supply.
This power source supplies the nonisolated side of the circuit,
including the ADE7953 energy metering IC and associated
circuitry. The 3.3 V supply should be provided on P1. The
isolated portion of the evaluation board is powered by the
interface board connection.
JUMPER CONFIGURATION
Tabl e 1 describes the jumpers included on the ADE7953 evaluation board and the required settings for different configurations.
Before connecting any high voltage signals, users should review
the jumper configuration and verify that it is correct for their
specific setup.
