1. Electrical Characteristics

1.1 Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any 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.

Notes: 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 VCC = 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 50mA.

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 50mA.

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.
