LQFP : FPT-100P-M05 package

QFP : FPT-100P-M06 package

Notes :

• For use as a 3.3 V single supply device, apply the same voltage to the VCC3 and VCC5 power supply pins.

• For use with a dual power supply, apply the respective voltages to the VCC3 and VCC5 power supply pins.

• In use with a dual power supply, a total of 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) can be used in a 5 V interface.

Note that all other pins must be used in 3 V interface.

• In use with a dual power supply, it is not possible to turn on only the 5 V or the 3 V power supply

independently. Always turn on both power supplies simultaneously. (It is recommended that the 3 V power

to the MB90470 series be turned on first.)
