Important notice
IMPORTANT NOTICE
For engineering development or evaluation purposes only
NXP provides the product under the following conditions:
This evaluation kit is for use of ENGINEERING DEVELOPMENT OR
EVALUATION PURPOSES ONLY. It is provided as a sample IC pre-
soldered to a printed-circuit board to make it easier to access inputs,
outputs and supply terminals. This evaluation board may be used with any
development system or other source of I/O signals by connecting it to the
host MCU computer board via off-the-shelf cables. This evaluation board
is not a Reference Design and is not intended to represent a final design
recommendation for any particular application. Final device in an application
heavily depends on proper printed-circuit board layout and heat sinking
design as well as attention to supply filtering, transient suppression, and I/O
signal quality.
The product provided may not be complete in terms of required design,
marketing, and or manufacturing related protective considerations, including
product safety measures typically found in the end device incorporating the
product. Due to the open construction of the product, it is the responsibility of
the user to take all appropriate precautions for electric discharge. In order to
minimize risks associated with the customers’ applications, adequate design
and operating safeguards must be provided by the customer to minimize
inherent or procedural hazards. For any safety concerns, contact NXP sales
and technical support services.

PCA8561AHN-ARD evaluation board
1 Introduction
This document describes the PCA8561AHN-ARD evaluation board. The evaluation board
is built around the PCA8561, automotive 18x4 LCD segment driver, produced by NXP
Semiconductors. The evaluation board serves as a daughter card that can be connected
through an Arduino port to various Arduino compatible (including original Arduino Uno
R3) EVK / mother boards with the purpose of testing and measuring the characteristics of
the PCA8561AHN Device Under Test (DUT).
The PCA8561 IC is an 18x4 LCD segment driver, automotive grade, is built in two
variants: the PCA8561AHN equipped with I2C-bus, and PCA8561BHN equipped with
SPI-bus. The PCA8561AHN-ARD daughter board is equipped with the I2C-bus version
of the LCD driver. The DUT (PCA8561AHN) drives the on-board LCD display “DE301-
RS-20/6.35”, and is controlled from the mother board through the Arduino port. The
board allow the user to test and measure the static and dynamic characteristic of the
PCA8561 IC for different configurations specified in the datasheet. The power supply is
provided from the same Arduino port.
Additionally, a Graphical User Interface (Windows platform) is provided to facilitate the
evaluation of the daughter board. The GUI is used with the following NXP evaluation
boards: IMXRT1050 EVK Board, LPCXpresso55S69 Development Board and i.MX 8M
Mini LPDDR4 EVK Board.
