The iPort/USB 2 (#MIIC-208) is an important addition to MCC's I2C Bus host adapter product line, offering a full range of voltage and performance capabilities required for the design and production of products using the latest generation of ICs and sensors.

This product brief describes features and benefits of the iPort/USB 2 (#MIIC-208) I2C Bus host adapter, and indicates differences between the iPort/USB 2 (#MIIC-208) and the previous generation iPort/USB (#MIIC-204).

In addition to the information provided below, detailed product information, drivers, development tools, and application software is available on the iPort/USB 2 Resource Page (http://www.mcc-us.com/iPortUSB-2).

Please note that the iPort/USB 2 is available in singles with I2C Bus Mini Clip-Lead Cable, USB Cable, and carrying case, or in 5 and 10 packs without cables or cases. We also offer standard and custom length I2C Bus cables.

Features, Benefits, and Differences:

1. Faster Throughput

Feature: The iPort/USB 2 (#MIIC-208) uses a new faster chipset.

Benefit: The iPort/USB 2 can communicate more data faster for I2C Bus data intensive applications.

Difference: 2x times faster than the iPort/USB (#MIIC-204).

2. Circuit SenseTM, Integrated Voltage Translation

Feature: The iPort/USB 2 (#MIIC-208) includes a new switch-selectable integrated Circuit Sense I2C Bus voltage level translation circuit. Circuit Sense allows iPort/USB 2 to work with a wide range of I2C Bus voltages from 0.5 volt to 5 volt.

Benefit: The iPort/USB 2 can adapt to a userís circuit High Logic Voltage Level (1) and Low Logic Voltage Level (0) based upon a user reference voltage signal.

Benefit: The iPort/USB 2 can work with very low voltage user devices, like battery powered watches and fitness bands, while also working with standard 1.8v, 3.3v, and 5v devices.

Benefit: The iPort/USB 2 can communicate with advanced low-voltage sensors.

Benefit: The iPort/USB 2 can adapt to a userís circuit voltage in real-time, so the iPort/USB 2 can automatically adjust logic levels to the battery or power supply voltage in a userís device.

Difference: The iPort/USB (#MIIC-204) communicates with 3.3v to 5v only devices, and requires an external voltage translation adapter to work down to 1.8v.

3. 3.3v or 5v Power Source

Feature: The iPort/USB 2 (#MIIC-208) includes a new slide switch controlled power source circuit. This allows the iPort/USB 2 to optionally deliver 100mA of 3.3v or 5v to a userís circuit.

Benefit: The iPort/USB 2 can supply power to a wide voltage range of user circuits.

Difference: The iPort/USB can only supply 5v to a userís circuit.

4. Mini I2C Bus Connector

Feature: The iPort/USB 2 (#MIIC-208) includes our new low-profile I2C Bus mini interface connector (http://www.mcc-us.com/I2CMiniInterfaceInfo.html).

Benefit: Custom I2C Bus cables are easier to make. Eliminates need for expensive cable making tools.

Benefit: Positive locking prevents accidental disconnection.

Benefit: Keyed to prevent reverse insertion.

Benefit: Low-profile fits in small spaces.

Difference: The iPort/USB (#MIIC-204) used a high-profile connector that required special cable making tools (http://www.mcc-us.com/ipicon.htm).

5. USB Powered

Feature: The iPort/USB 2 is USB bus-powered.

Benefit: No external power supply is required.

Difference: The iPort/USB (#MIIC-204) uses an optional external power supply to deliver extra power to a userís circuit.

6. I2C Bus Circuit Protection

Feature: The iPort/USB 2 (#MIIC-208) includes a three-stage advanced I2C Bus over-voltage, reverse-voltage, and ESD protection circuitry.

Benefit: Helps protect a userís host computer if a high or reverse voltage or power spike is accidentally attached to the I2C Bus.

Benefit: Helps protect the iPort/USB 2 if a high or reverse voltage or power spike is accidentally attached to the I2C Bus.

Difference: The iPort/USB (#MIIC-204) includes limited OV/RV/ESD protection.

7. Application Software Compatible

Feature: The iPort/USB 2 is software compatible with all our ASCII-text based I2C Bus adapters including the iPort/AI (#MIIC-202), iPort/AFM (#MIIC-203), iPort/USB (#MIIC-204), iPort/LAN (#MIIC-205), i2cStick (#MIIC-207), and the new iPort/AFM 2 (#MIIC-213).

Benefit: User custom application software may not need any changes to use the iPort/USB 2.

Benefit: Compatible with MCC's MS.NET Class Library and LabVIEW VI Library.

Benefit: User systems designed to work with one type of MCC adapter interface (RS-232, USB, or Ethernet) can move to another interface type without the need to re-program custom application software.

Benefit: Extends the useful life of user's custom application software, product programming environment, and production test systems.
