User manual
This document describes the PCAL6534EV-ARD evaluation board. The evaluation
board is built around the PCAL6534, low-voltage translating, 34-bit 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 / motherboards for testing and measuring the characteristics of the PCAL6534
Device Under Test (DUT).
The PCAL6534EV-ARD daughter card communicates through the Arduino port with the
host device via the Fast-mode I
lines allows the motherboard to control the DUT through the same Arduino port.
Power is delivered from the motherboard (EVK) through the Arduino port also.
The I/O pins of the DUT are organized in five ports. The port P0, P1, P2, and P3 are 8-bit
wide, while P4 has two bits only. The port P0 and P1 controls an on-board four-digit LED
display through the MAX V CPLD (Intel/Altera). The board contains also eight on-board
LEDs and five switches, connected to the I/O pins of the DUT. All I/O lines are shared
with three connectors for external access to the I/O pins.
Additionally, a Graphical User Interface (Windows platform) 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.
NXP Semiconductors provides online resources for evaluation board and its supported
