NXP I2C demonstration board 2005-1 kit
Introduction
Expandable Low-Cost I2C-Based Demonstration Board Kit Offers Easy Programming and Evaluation of I2C Devices
As the inventor and world leader in I2C devices, we have a vast portfolio of I2C interface products used to control, expand, and interconnect I2C-bus systems.
These products include general purpose I/O expanders, LED blinkers/dimmers/controllers, repeaters/hubs/extenders, real-time clock/calendars, temperature sensors, DIP switches, multiplexers and switches, bus controllers, and serial EEPROMs.
The I2C Demonstration Board 2005-1 is an I2C-based system that allows field application engineers, designers, and educators to use their Personal Computer (PC) to easily test, demonstrate, and experiment with I2C interface devices.
The demonstration board is a valuable training tool that allows multiple operations to be performed in a setting similar to a real system environment.
A standard USB port provides bi-directional communication with the I2C devices allowing easy manipulation of the I2C devices without the need for an external power supply.
An on-board LED illuminates after the USB host has successfully enumerated it.
The Win-I2CUSB Lite software runs on Windows 98SE, ME, 2000, or XP and is compatible with any PC hardware having a minimum of a Pentium processor and an USB port.
The Win-I2CUSB Lite software is a custom version of the popular graphical user interface (GUI) supplied by The Boardshop.
This version is designed to operate only with the specific devices and device addresses on the I2C Demonstration Board 2005-1 and subsequently issued daughter cards.
The software has easy-to-use menus to let you select the device you want to control at bus frequencies up to 400kHz.
Via the Options menu, it is possible to control the I2C frequency and the switched 3.3- and 5.0-V power supplies.
The GUI, shown controlling the PCA9531 8-bit LED dimmer interface, provides easy-to-use point-and-click control of the I2C devices without any technical knowledge.
The software has control panels for all the devices on the board.
There is also a Universal Mode that allows users to create their own limited length I2C commands.
A full version of the Windows GUI software is included in a product called Win-I2CUSBDLL kit.
The full version of the software operates over the entire address range, supports all I2C devices, and has a more powerful Universal Mode.
The Win-I2CUSBDLL kit can be purchased from The Boardshop.
The Win-I2CUSBDLL kit includes its own USB-to-I2C hardware adapter which is incompatible with the NXP I2C Demonstration Board 2005-1.
To use the full version of the GUI with the NXP demonstration board, simply remove the microcontroller from the Win-I2CUSBDLL kit's USB-to-I2C hardware adapter and insert it into the microcontroller socket located on the NXP demonstration board.

USB Cable
The USB cable connects a personal computer's USB port to the I2C Demonstration Board 2005-1.
The cable carries USB signals from the Windows desktop or notebook computer to the demonstration board's onboard microcontroller for conversion to the I2C-bus SCL/SDA signals.
It also carries up to 500mA of 5V unregulated power from the USB port.
External Temperature Sensor
The remote channel of the SA56004 can monitor a diode junction such as the substrate PNP of a microprocessor or a diode-connected transistor such as a 2N3904 (NPN) or 2N3906 (PNP).
With factory trimming, remote sensor accuracy of ±1°C is achieved.
The provided 2N3906 PNP transistor plugs into the board to the left of the SA56004.
Win-I2CUSB Lite Software
This Windows-based software application provides device-specific and Universal Mode graphical interfaces between the PC and the I2C-bus slaves featured on the I2C Demonstration Board 2005-1.
The software is compatible with Windows 98SE, ME, 2000, and XP.
It is available as a download only.
Operating Instructions
A Quick Start Guide provides setup procedures.
Detailed software operating procedures and experiments are contained in a User Manual and Training Exercises document.
Both documents are available as downloads only.
