v.3 20070619 Many of today’s applications require longer buses and/or faster speeds. Fast-mode Plus was
introduced to meet this need by increasing drive strength by as much as 10× and increasing the
data rate to 1 Mbit/s while maintaining downward compatibility to Fast-mode and Standard-mode
speeds and software commands.

C-bus specification
v2.0 1998 The I
2
C-bus has become a de facto world standard that is now implemented in over 1000 different
ICs and licensed to more than 50 companies. Many of today’s applications, however, require higher
bus speeds and lower supply voltages. This updated version of the I
2
C-bus specification meets those
requirements.
