*1: A wide operating voltage range is guaranteed but an
abrupt voltage variation in the access status of the
MPU is not guaranteed.
*2: When the voltage is Tripled, care must be paid to
supply the voltage VSS so that operating voltage of
VOUT and V5 may not be exceeded.
*3: D0 ~ D5, D6 (SCL), D7 (SI), A0, RES,
CS WR (E),
P/S, IF
*4: This is a resistance value when a voltage of 0.1 V is
applied between output pin SEGn, SEGSn, COMn or
COMSn, and each power pin (V1, V2, V3 or V4). It
is specified in the range of operating voltage (2).
RON = 0.1 V /
I
(
I: Current flowing when 0.1 V is
applied between the power and output)
