PCAL6416AEV-ARD evaluation board
1 Introduction
This document describes the PCAL6416AEV-ARD evaluation board. The evaluation
board is built around the PCAL6416A, low-voltage translating, 16-bit I
2
C-bus/SMBus I/
O expander with interrupt output, reset, and configuration registers, 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 PCAL6416A Device Under Test (DUT).
The PCAL6416AEV-ARD daughter card communicates through the Arduino port with
the host device via the Fast-mode I
2
C-bus. Alongside the I
2
C bus, three additional digital
lines allow the mother board to control the DUT through the same Arduino port.
Power is also delivered from the mother board (EVK) through the Arduino port.
The board contains eight on-board LEDs and eight switches, connected to the I/O pins of
the DUT. The same I/O bus is shared with a connector for external access to the I/O pins.
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.
