NXP I2C 2002-1A evaluation board kit
NXP I2C 2002-1A evaluation board kit
New I2C Evaluation Kit Offers Easy Programming and Evaluation of I2C Device Solutions
NXP I2C evaluation board kit includes a Personal Computer graphical interface that allows easy manipulation of I2C devices.
The I2C 2002-1A Evaluation Board is a low-cost I2C-based system that allows Field Application Engineers, designers, and educators to use their Personal Computer (PC) to easily test and demonstrate new I2C devices in a platform that allows multiple operations to be performed in a setting similar to a real system environment.
- I2C 2002-1A Evaluation Board - a 13cm x 14cm 2-layer printed circuit board that included the following I2C slave devices:

to access full product/package information.
- I2CPORT v2 Adapter Card - plugs into the PC parallel port and provides the interface between the PC (bus master) and the I2C bus slaves on the evaluation board at speeds over 100kHz.
- 4-Wire Connection Cable - connects the I2CPORT v2 Adapter Card with the I2C 2002-1A Evaluation Board at normal SDA/SCL signal levels.
- USB Adapter Card - connects the I2CPORT v2 Adapter Card with the I2C 2002-1A Evaluation Board through a USB cable (cable not included) via the P82B96. NOTE: This is not a normal USB connection. The USB cable and USB connectors are used to carry the SCL/SDA signals at the special P82B96 voltage levels.
- 9V Power Supply - provides power to the evaluation board, devices, and LEDs. Operates from 100 to 240 volts at 47 to 66 hertz. Edison plug on one side and 9 volt 1.33A mini-plug on the other side.
- CD-ROM - contains operating instructions and Win-I2CNT software.
- Operating Instructions - detailed application notes, software operating procedures, and setup procedures.
- Win-I2CNT (32-Bit) - application software that provides the device specific and universal mode graphical interfaces between the PC and I2CPORT v2 Adapter Card to control the I2C bus slaves featured on the I2C 2002-1A Evaluation Board. Compatible with Windows 95, 98, ME, NT, 2000, and XP.
The devices used on the evaluation board are representative of the various general purpose I2C product families being introduced by NXP Semiconductors.
They were selected for the following reasons:
- PCA9501 - to show the programming difference between the PCF8574 8-bit GPIO (of which the PCA9501 has the same state machine) and the PCA9554 8-bit GPIO (more complex state machine) and to showcase this new device which has both the PCF8574 GPIO and PCF8582C-2 2Kbit serial EEPROM contained in the same package with 6 address pins that allow up to 64 devices on the same bus.
- PCA9561 - to show its use as a 6-bit DIP switch replacement.
- PCA9543 - to show its use as a 2 channel multiplexer/switch.
- PCA9554/55 - to show how I/O expanders can be used as LED drivers, how they can be used to provide input and output to the bus master and to show the size comparison of the PCA9555 in three different 24-pin packages: the large surface mount (SOIC - D), the smaller Thin Small Surface Package (TSSOP - PW) and the very small Heat Sink Very Thin Quad Flat Pack No Leads Package (HVQFN - BS).
- PCA9550/51 - to show how the LED Blinkers blink LEDs and to show how unused bits can be used as general purpose inputs and outputs.
- PCF8582C-2 - to show 2Kbit EEPROMs and have two identical devices to multiplex with the PCA9543.
- LM75A - to show temperature sensors with interrupt output and have two identical devices to multiplex with the PCA9543.
- PCA9515 and P82B96 - to show I2C bus expanders allow larger loading on the I2C bus and to be able to connect a second card to the first evaluation board. To show how the P82B96 can be used to send both the I2C clock, data signal, and power supply over USB cables or telephone wires.
Some of the experiments and demonstrations that can be shown include:
- Program and Blink LEDs using the GPIOs and/or the LED Blinker Devices
- Learn differences in programming and blinking LEDs using the older and newer GPIOs and the 2/8-bit LED blinkers
- See LED blinker continue to blink LEDs when the I2C bus is disconnected
- Command Temperature Sensors and 2K EEPROMs with Same and Different Addresses through the PCA9543 2-Channel Switch that is used as a Multiplexer and for Voltage Translation between 3.3 and 5 Volts
- Learn how the multiplexer, 2Kbit serial EEPROM, and temperature sensor work
- See what happens when the master sends commands to devices with the same address at the same time
- See temperature sensor response at different voltage levels
- Program the Multiplexed I2C EEPROM as a DIP Switch Replacement
