8.2Recommended Operating Conditions

PARAMETER	SYMBOL	MIN	MAX	UNITS	COMMENTS
Operating	TA	0	70	°C
Temperature
1.8V supply voltage	VDDA18PLL	1.71	1.98	V
	VDD18
3.3V supply voltage	VDDA33	3.0	3.6	V
	VDDA33PLL
	VDD33
Voltage on any I/O pin		-0.3	5.5	V	If any 3.3V supply voltage drops
					below 3.0V, then the MAX
					becomes:
					(3.3V supply voltage + 0.5)
Voltage on XTAL1		-0.3	VDDA33	V
Voltage on XTAL2		-0.3	VDD18	V
