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-theshelf 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.

Introduction

The P3T1755DP-ARD evaluation board features an I3C, I2C-bus, 0.5 °C accuracy, digital temperature sensor. A graphical interface allows the user to easily explore the different functions of the driver. The board can be connected in parallel with other I2C-bus demo boards to create an evaluation system.

The IC communicates to the host via the industry standard I2C-bus port. The evaluation software runs under Microsoft Windows 7, 8, or 10 PC platform.

• Easy to use GUI-based software demonstrates the capabilities of the P3T1755DP
  On-board temperature sensor for system thermal management experiments

• Convenient test points for easy scope measurements and signal access

• USB interface to the host PC

• Power supply from USB port (x2) or external power supply can be used to power P3T1755DP-ARD evaluation board

Getting started

Assumptions

Familiarity with the SPI-bus is helpful but not required.

Static handling requirements

CAUTION

This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. You must use a ground strap or touch the PC case or other grounded source before unpacking or handling the hardware.

Minimum system requirements

• PC Pentium processor (or equivalent)
• One USB port (either 3.0 or 2.0 or 1.1 compatible)
• Windows 7, 8, or 10
• MIMXRT685-EVK MCU board (from www.nxp.com)

Power requirements

The MIMXRT685-EVK MCU board obtains power from the PC USB port. Two USB parts can be connected to the MIMXRT685-EVK MCU board simultaneously. Use an external power supply option if exceeding the USB port current capabilities.

Hardware installation

P3T1755DP-ARD EV board and MIMXRT685-EVK MCU board connection

The P3T1755DP-ARD evaluation board is connected to an MIMXRT685-EVK MCU board using four connectors (J4/J5/J7/J8 on P3T1755DP-ARD board and J27/J28/J29/J30 on MIMXRT685- EVK board) for I2C-bus and power supply, and one connector (J18 on P3T1755DP-ARD board and J on  MIMXRT685-EVK board) for I3Cbus.

The MIMXRT685-EVK MCU board communicates with P3T1755DP-ARD demo GUI through PC USB port and uses I2C or I3C-bus to communicate to P3T1755.

Use J7 (USB Micro-B connector) on MIMXRT685-EVK for power supply and GUI communication port.
