Absolute Maximum Ratings

Table 12. Absolute Maximum Ratings

Symbol	Description	Min	Typ	Max	Units	Notes
TSTG	Storage Temperature	-55	25	+100	oC	Higher storage temperatures
						reduce data retention time. Recom-
						mended storage temperature is
						+25oC ± 25oC. Extended duration
						storage temperatures above 65oC
						degrade reliability.
TA	Ambient Temperature with Power Applied	-40	–	+85	oC
Vdd	Supply Voltage on Vdd Relative to Vss	-0.5	–	+6.0	V
VIO	DC Input Voltage	Vss -	–	Vdd +	V
		0.5		0.5
VIOZ	DC Voltage Applied to Tri-state	Vss -	–	Vdd +	V
		0.5		0.5
IMIO	Maximum Current into any Port Pin	-25	–	+50	mA
ESD	Electro Static Discharge Voltage	2000	–	–	V	Human Body Model ESD.
LU	Latch-up Current	–	–	200	mA

Operating Temperature
Table 13.	Operating Temperature
Symbol	Description	Min	Typ	Max	Units	Notes
TA	Ambient Temperature	-40	–	+85	oC
TJ	Junction Temperature	-40	–	+100	oC	The temperature rise from ambient
						to junction is package specific. See
						Table 40 on page 38. The user must
						limit the power consumption to
						comply with this requirement.

DC Electrical Characteristics

DC Chip-Level Specifications

Table 14 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C

≤TA ≤ 85°C, 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to 5V, 3.3V, or 2.7V at 25°C and are for design guidance only.
