MASK OPTION LIST
*1: The oscillation stabilization delay time is generated by dividing the original clock oscillation. The time described
in this item should be used as a guideline since the oscillation cycle is unstable immediately after oscillation
starts. “F
C
” indicates the original oscillation frequency.
*2: –101 is provided respectively for the MB89P195 OTP versions as the standard product.
No.
