AT89LP51/52 - Preliminary

18. Electrical Characteristics

Notes:

1. Under steady state (non-transient) conditions, IOL must be externally limited as follows:

Maximum I

OL per port pin: 10 mA

Maximum total I

OL for all output pins: 100 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 conditions.

2. Minimum VDD for Power-down is 2V.

3. All characteristics contained in this datasheet are based on simulation and characterization of other microcontrollers manu-

factured in the same process technology. These values are preliminary values representing design targets, and will be

updated after characterization of actual silicon.

18.1

Absolute Maximum Ratings*

Operating Temperature ................................... -40°C to +85°C

*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 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.

Storage Temperature ..................................... -65°C to +150°C

Voltage on Any Pin with Respect to Ground ......-0.7V to +5.5V

Maximum Operating Voltage ............................................ 5.5V

Total DC Output Current ........................................... 150.0 mA
