NTS0304EUK-ARD evaluation board
1 Introduction
This document describes the NTS0304EUK-ARD evaluation board. The evaluation
board is built around the NTS0304E, a 4-bit dual supply translating transceiver controlled
via the I
2
C-bus, produced by NXP Semiconductors. The evaluation board serves as
a daughterboard that can be connected through an Arduino port to various Arduino
compatible (including original Arduino Uno R3) EVK / motherboards with the purpose of
testing and measuring the characteristics of the NTS0304E Device Under Test (DUT).
The NTS0304EUK-ARD daughterboard allows the ability to test and measure the static
and dynamic characteristics of the DUT by accessing a digital potentiometer with SPI and
I
2
C interface. Alongside the digital potentiometer, the board contains a loopback circuit
allowing the user to test the bidirectional capabilities of the DUT IC.
The DUT is tested for different logic levels applied to both sides of the level translator, by
supplying the NTS0304E IC with two independent voltage programmable power supplies.
The power supplies are controlled by the motherboard (EVK) through the same Arduino
port. Power is delivered from the motherboard (EVK) through the Arduino port also.
Additionally, a Windows Graphical User Interface (GUI) is provided to facilitate the
evaluation of the daughterboard. The GUI is used with the following NXP evaluation
boards: IMXRT1050 EVK Board, LPCXpresso55S69 Development Board and i.MX 8M
Mini LPDDR4 EVK Board.
