I²C and SPI Triggering and Decode for
Infiniium 8000 and 90000 Oscilloscopes
Data Sheet
Quickly decode I²C
and SPI serial packets
Lower-speed serial bus interfaces are
widely used for connecting EEPROMs,
DACs, ADCs, and other peripheral ICs
to microcontrollers and processors.
Because these interfaces are relatively
simple to implement and have few
wires taking up board space, they are
found in a wide array of embedded
designs. Two common low-speed serial
bus interfaces found pre-packaged on
many vendors’ ICs are inter-integrated
circuit (I²C) and serial peripheral
interface (SPI).
The N5391A triggering and decode
for I²C and SPI software provides
the integration of the Infiniium
oscilloscope, a powerful everyday
signal integrity test tool, with protocol
analysis capabilities. With this
integration, you can isolate serial
packets to find sources of errors
due hardware related problems and
software related problems. Quickly
pinpoint timing or signal integrity
issues such as noise or coupling on
your I²C or SPI bus. Easily see the
information transfer leading up to or
following a particular event or failure.
Effectively troubleshoot an embedded
system capturing and decoding I²C or
SPI buses, correlating them with other
signals in the design, such as digital
control signals using a mixed signal
oscilloscope (MSO), and analog signals
interfacing with the real world.
