*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.

1. “Max” means the highest value where the pin is guaranteed to be read as low
2. “Min” means the lowest value where the pin is guaranteed to be read as high
3. Although each I/O port can sink more than the test conditions (0.5mA at V
CC
= 1.8V) under steady state conditions (non-
transient), the following must be observed:
1] The sum of all IOL, for ports B0 - B5, should not exceed 50 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
4. Although each I/O port can source more than the test conditions (0.5mA at Vcc = 1.8V) under steady state conditions (non-
transient), the following must be observed:
1] The sum of all IOH, for ports B0 - B5 should not exceed 50 mA.
If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.
5. Minimum V
CC
for Power-down is 2.5V.
6. Based on standard voltage range (2.7V - 5.5V) characterization results. To be confirmed after actual silicon characterization.
