AT89S53  
Absolute Maximum Ratings*  
*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.  
Operating Temperature.................................. -55°C to +125°C  
Storage Temperature..................................... -65°C to +150°C  
Voltage on Any Pin  
with Respect to Ground.....................................-1.0V to +7.0V  
Maximum Operating Voltage............................................. 6.6V  
DC Output Current...................................................... 15.0 mA  
DC Characteristics  
The values shown in this table are valid for TA = -40°C to 85°C and VCC = 4.0V to 6.0V, unless otherwise noted.

Notes: 1. Under steady state (non-transient) conditions, IOL  
must be externally limited as follows:  
Maximum IOL per port pin: 10 mA  
Maximum IOL per 8-bit port:  
Maximum total IOL for all output pins: 71 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.  
Port 0: 26 mA  
Ports 1,2, 3: 15 mA  
2. Minimum VCC for Power Down is 2V.
