I2C bus serial information is displayed as parallel bytes in state mode |
|
Two alternate display modes provide detail or overview of bus transactions |
|
Quickly determine the information content of I2C transactions |
|
Operates at low voltage with user-defined threshold levels of 0.5V to 3.0V |
|
View details of I2C bus timing with signal pass-through mode |
|
View transaction duration in state mode using time tags, or in timing mode |
|
Start- and stop- conditions and byte boundaries are detected by the analysis probe hardware and displayed in timing mode |
|
View I2C symbolic address while in timing mode |
|
Operates simultaneously in both timing and state modes – no double-probing required |
|
Operates non-invasively in real-time at both 100 KHz and 400 KHz fast-mode |
|
Decodes 7-bit and 10-bit addresses in state mode |
|
Preprocessor display shows current message address and message count |
|
Save measurement setup time with automatic configuration software for the logic analyzer |
|
Does not require termination adapters |
|
Includes all of the features of the ALD-232A Analysis Probe (RS232, RS449, and IEEE1284) |
With this comprehensive solution, designers can view I2C transactions, locate hardware faults, characterize software timing, verify performance specifications, and successfully troubleshoot I2C-based systems. In conjunction with processor-specific support available with Agilent logic analyzers, users can observe time-correlated processor and bus activity. This solution provides a complete view of all I2C activity, and is compatible with current Agilent logic analyzers.
The I2C bus protocol has been adopted by many chip suppliers as an economical, simple solution to 8-bit digital control applications to avoid problems of confusion, data loss, and blockage of information, and to minimize the number of IC packages required to implement a circuit. Advanced Logical Design’s I2C Bus Analysis Probe Solution conforms to the I2C specification as developed by Philips Semiconductor. It has been specifically designed to monitor data transfers, data validity, start and stop conditions, and data acknowledgement.
Additionally, Agilent logic analyzers support a number of microprocessors which have I2C peripherals. By connecting multiple analysis probes, complete debugging of I2C systems can be accomplished.
