Notes :•MB90485 series only
• P40 to P47 and P70 to P77 are N-ch open drain pins with control, which are usually used as CMOS.
• P76 and P77 are open drain pins without P-ch.
• For use as a single 3 V power supply products, set VCC = VCC3 = VCC5.
• When the device is used with dual power supplies, P20 to P27, P30 to P37, P40 to P47 and
P70 to P77 serve as 5 V pins while the other pins serve as 3 V I/O pins.
