CHAPTER 2 PIN FUNCTIONS
2.1 List of Pin Functions
The names and functions of the pins of the V850/SB1 and V850/SB2 are described below divided into port pins
and non-port pins.
There are three types of power supplies for the pin I/O buffers: AV
DD
,
BV
DD
, and EV
DD
. The relationship between
these power supplies 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 to 5.5 V.
Differences in pins between the V850/SB1 and V850/SB2 are shown below.
