Pinout




Specifications

Maximum ratings are the extreme limits to which the microcontroller unit (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 V_In and V_Out within the range V_SS (V_In or V_Out) V_DD. Connect unused inputs to the appropriate voltage level, either V_SS or V_DD.

Rating	Symbol	Value	Unit
Supply voltage	VDD	0.3 to +7.0	V
Current drain per pin excluding VDD and VSS	I	25	mA
IRQ pin only	VIn	VSS 0.3 to 2 x VDD + 0.3	V
Storage temperature range	TSTG	65 to +150

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