2.1 List of Pin Functions

The names and functions of pins of the V850/SB1 and V850/SB2 are described below with dividing into port pins
and non-port pins.
There are three types of power supplies for the pin I/O buffers: AV
these power supply and the pins is described below.

Caution The electrical specifications in the case of 3.0 V to up to 4.0 V are different
from those for 4.0 V to 5.5 V.
Differences of pins between the V850/SB1 and V850/SB2 are shown below.
