I2C Bus Monitor Plus

I²C Bus Monitor Plus

Part Number #MIIC-102

The I²C Bus Monitor Plus is our laboratory grade troubleshooting instrument for the Inter-Integrated Circuit (I²C) Bus, SMBus, and other derived protocols. When connected to an I2C or derived protocol bus and a host computer, the I²C Bus Monitor Plus captures, filters, and displays bus message data and timing information.

PRODUCT HIGHLIGHTS

Microsecond Timestamping of Bits, Bytes and Messages.

Non-intrusive capture of bus traffic to 400KHz.

Software controlled SCL and SDA Logic Voltage Levels.

Display Filtering on message Slave Address, R/W, Ack/Nack, Data Bytes, and Smart Battery System Protocol Violations.

If your designs include heavy I²C Bus, SMBus, or derived protocol content, the I²C Bus Monitor Plus will give you the bus monitoring power you need, including data timestamping, variable logic voltage thresholds, and flexible triggering. Whether you're testing designs with a single master and slave, such as programming configuration EEPROMs, or monitoring multiple masters and slaves in a server maintanence system, the information packed screens help you get your debug and verification done faster.

ADDITIONAL FEATURES

I²C Bus, SMBus, SSI, and IPMI Development Tool.
256K byte Data Recording Memory.
Supports General Calls, and Multi-Master/Multi-Slave Addressing.
Displays Start/Stop Events, Device Addresses, Read/Write Requests, Acknowledgements, Data, and Bit, Byte, and Message timing.
Trigger Input for synchronization with external events.

Trigger Output on bus events or pattern match for triggering external test equipment.

TYPICAL APPLICATIONS

Product Development: Software/Hardware Development, Testing, and Troubleshooting.

Manufacturing: Manufacturing Tests, Inspection, Quality Control.

The I²C Bus Monitor Plus includes an extensive array of message monitoring capabilities, and can time-stamp bits, bytes, or messages.

The I²C Bus Monitor Plus can display Smart Battery Data in engineering units, and can detect, filter, and display protocol violations.
