13.3 Maximum Ratings

Maximum ratings are the extreme limits to which the MCU can be exposed without permanently damaging it.

The MCU contains circuitry to protect the inputs against damage from high static voltages; however, do not apply voltages higher than those

shown in the table here. Keep VIn and VOut within the range

VSS ≤ (VIn or VOut) ≤ VDD. Connect unused inputs to the appropriate voltage level, either VSS or VDD.

Rating(1)	Symbol	Value	Unit
Supply voltage	VDD	–0.3 to +7.0	V
Input voltage	VIn	VSS –0.3	V
		to VDD +0.3
Programming voltage	VPP	VDD –0.3 to
		16.0
		VSS – 0.3
Bootstrap mode (IRQ pin only)	VIn		V
		to 2 x VDD + 0.3

Current drain per pin excluding	I	25	mA
VDD and VSS

Storage temperature range	TSTG	–65 to +150	° C

1. Voltages referenced to VSS

NOTE: This device is not guaranteed to operate properly at the maximum ratings. Refer to 13.7 5.0-Volt DC Electrical Characteristics and 13.8 3.3-Volt DC Electrical Characteristics for guaranteed operating conditions.

13.6 Power Considerations

The average chip junction temperature, TJ, in ° C can be obtained from:

TJ = TA + (PD x θ JA)

(1)

Where:

TA = ambient temperature in ° C

θ JA = package thermal resistance, junction to ambient in ° C/W

PD = PINT + PI/O

PINT = ICC × VCC = chip internal power dissipation

PI/O = power dissipation on input and output pins (user-determined)

For most applications, PI/O < PINT and can be neglected.
Ignoring PI/O, the relationship between PD and TJ is approximately:
PD =		K	(2)

	TJ	+ 273° C

Solving equations (1) and (2) for K gives:
= PD x (TA + 273° C) + θ JA x (PD)2			(3)

where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for any value of TA.
