I2C Bus Monitor (MIIC-101) Protocol Analyzer
Overview
The MIIC-101 I2C Bus / SMBus Monitor is a Stand-Alone and Remote Troubleshooting Tool for the I2C (Inter Integrated Circuit) serial bus developed by Philips Semiconductor, or the System Management Bus (SMBus) developed by Intel, and other dervived protocols.
When connected to an I2C Bus, or SMBus network, the MIIC-101 Bus Monitor can collect, display or upload information on all bus activity.
Key Features
- I2C and SMBus Compatible.
- Operating Modes include: Line Status, Forward/Backward Trace, View and Remote.
- Monitor ALL or SELECTED Bus Address.
- Stores up to 2700 messages Stand-alone. Unlimited storage in Remote Mode.
- Real-Time Trace to 100Kbit/s.
- Supports General Calls, and 7 bit Addressing.
- Displays Start/Stop Events, Device Addresses, Read/Write Requests.
- Built-in Alphanumeric Display and Keypad supports Byte, Message and Buffer Scrolling for stand-alone handheld portable operation.
- Optional Windows-based I2C Analyzer Software Package lets you see message traffic on your PC's screen, provides extended message filtering, and can record messages to disk.
- Powered by internal Battery, external Supply, or Bus Power.
- Compatible with 3.3v to 5v.
Tipical Applications
- Development: Software/Hardware Troubleshooting.
- Manufacturing: Testing and Debugging, Quality Control.
- Field Service: Field diagnosis, Repair Service, Verification.
