Built-in power supply
*1: A wide operating voltage range is guaranteed but an
abrupt voltage variation in the access status of the
MPU is not guaranteed.
*2: The operating voltage range is applicable to the case
where an external power supply is used.
*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 (V
1, V2, V3 or V4). It
is specified in the range of operating voltage (2).

ON = 0.1 V / ∆I
(∆I: Current flowing when 0.1 V is ap-
plied between the power and
output)
