Note:
1. If only a power supply of 3.3 V is used, apply the same voltage to both V
2. If using two power supplies, apply voltage to each of V
For two power supplies, 32 pins (P20/A16 to P27/A23/PPG3, P30/A00/AIN0 to P37/A07/PWC1, P40/A08/SIN2 to P47/
A15/OUT5, and P70/SIN0 to P77/SDA) in total are used with a 5-V interface at all operation mode. Note that all other
pins use a 3-V interface.
If two power supplies are used, neither of the following cases is allowed: only a 5 V power supply is turned on; or only
a 3-V power supply is turned on. Turn on both power supplies. (Fujitsu recommends that the 3-V power supply is
turned on first.)
