DIFFERENCES BETWEEN MSM80C31F/MSM80C51F AND MSM80C31/MSM80C51

• Operating frequency

0.5 to 16 MHz ..................... MSM80C31F-1/MSM80C51F-1

0.5 to 12 MHz ..................... MSM80C31/MSM80C51/MSM80C31F/MSM80C51F

• External clock input terminal

XTAL1 ................................. MSM80C31F(-1)/MSM80C51F(-1)

XTAL2 ................................. MSM80C31/MSM80C51

• Emulation mode

Output impedance of ALE and PSEN pins becomes about 20 kW while CPU is being reset in

MSM80C31F/MSM80C51F.

Any other functions and electrical characteristics of MSM80C31F/MSM80C51F except for

above three differences are the same as those of MSM80C31/MSM80C51.
