Specifications
Absolute Maximum Ratings
at Ta = 25°C, V
SS
= 0 V
Note: 1. Applies to open drain output specification pins. The rating from the “other pin” entry applies for specifications other than the open drain output
specification.
2. Levels up to the free-running oscillation level are allowed for the oscillator input and output pins.
3. Inflow current (For P8, the CMOS output specifications apply.)
4. Outflow current (Applies to pull-up output specification and CMOS output specification pins except P8.)
5. We recommend using reflow soldering methods to mount the QFP package version.
Contact your Sanyo sales representative to discuss process conditions if techniques in which the whole package is immersed in a solder bath
(solder dip or spray techniques) are used.
Allowable Operating Ranges
at Ta = –30 to + 70°C, V
SS
= 0 V, V
DD
= 3.0 to 5.5 V unless specified otherwise
Note: 1. Applies to open drain specification pins. However, the rating for V
IH
(2) applies to the P33/HOLD pin. Ports P2, P3 and P6 cannot be used as input
pins when CMOS output specifications are used.
2. Applies to open drain specification pins. P9, which has CMOS output specifications, can be used as input pins.
3. When PE is used as a three-value input, V
IH
(4), V
IM
and V
IL
(4) apply. Port PC cannot be used as input pins when CMOS output specifications
are used.
