Caution Three power supply systems are available to supply power to the I/O buffers of the V850/SB1’s
pins: EVDD, BVDD, and AVDD. The voltage ranges that can be used for these I/O buffer power
supplies are shown below.
EVDD, BVDD: 3.0 V to 5.5 V
AVDD: 4.5 V to 5.5 V
The electrical specifications differ depending on whether the power supply voltage range is 3.0
V to under 4.0 V, or 4.0 V to 5.5 V.
