I2C Development Tools

The JI-216 I2C Bus Monitor is a low cost, easy-to-use PC hosted instrument specifically
designed for troubleshooting and debugging I2C networks. The JI-216’s FPGA based
architecture provides for the capture and display of all valid or invalid messages and I2C
bus events. Captured I2C messages are available for display in two modes: real-time
streaming, or triggered. These modes provide optimized data display for either hardware
or software development. The SDA/SCL timing display aids in tracking down and solving
hardware timing problems. JI-216’s broad bandwidth (DC – 3.4Mbits/s), wide input signal
range (0 – 15.0V), and variable signal filtering provides flexibility in monitoring a variety of
I2C bus systems. An intuitive Windows application manages instrument setup and
control. Communications and unit power is provided via a USB 2.0 link.

Compatible with Standard-mode (100kbit/s), Fast-mode (400kbit/s), Fast-mode
Plus (1.00Mbits/s), and High-Speed mode (3.4Mbit/s)

Time stamping and message period timer

I2C messages displayed in either Real-time Streaming* or Trigger mode

USB 2.0 host interface – No external power required

* Real-time streaming mode limited to a maximum, sustained throughput rate of 1.0Mbits/s
