Notes on differences between 3851 group
(built-in 16 KB ROM), 3851 group (built-in 24
KB or more ROM)
(1) The absolute maximum ratings of 3851 group (built-in 24 KB or
more ROM) is smaller than that of 3851 group (built-in 16 KB
ROM).
Power source voltage Vcc = 0.3 to 6.5 V
CNVss input voltage
VI = 0.3 to Vcc +0.3 V (M38514M6, M38517M8)
VI = 0.3 to 6.5 V (M38517F8)
(2) The oscillation circuit constants of XIN-XOUT, XCIN-XCOUT may
be some differences between 3851 group (built-in 16 KB
ROM) and 3851 group (built-in 24 KB or more ROM).
(3) Do not write any data to the reserved area and the reserved
bit. (Do not change the contents after reset.)
(4) Fix bit 3 of the CPU mode register to 1.
(5) Be sure to perform the termination of unused pins.
