Table 7-1. DC Characteristics – All InterfacesApplicable over the recommended operating range from T_A = -40°C to +125°C, V_CC = +2.7V to +5.5V.
Parameters	Test Conditions	Symbol	Min.	Typ.	Max.	Units	Type⁽¹⁾
Supply Voltage on Pin V_CC	—	V_CC	2.7	—	5.5	V	A
Supply Current on Pin V_CC	Active mode⁽⁴⁾	I_{IO_Active}	—	25	40	mA	A
	Idle mode⁽²⁾ (T_A = +85°C)	I_{IO_Idle}	—	—	10	mA	B
	Sleep mode	I_{IO_Sleep}	—	7	15	uA	B
V_CC Rise Rate	—	V_RISE	—	—	0.1	V/µs	C
High-Level Input Voltage	—	V_IH	0.7 x V_CC	—	V_CC + 0.3	V	A
Low-Level Input Voltage	—	V_IL	-0.3	—	0.3 x V_CC	V	A
Theta JA	—	ϴ_JA	—	73	—	℃/W	8-Pin SOIC
Theta JA	—	ϴ_JA	—	41.3	—	℃/W	24-pad VQFN

Note:

Type means: A = 100% tested, B = characterized, C = design parameter
Idle means that power is applied, the device is NOT in Sleep mode and no commands nor instructions are running.
The state of the V_CC latches will be retained so long as V_CC remains above the V_POR level.
Active current is measured with all GPIO pins either driven to ground or configured as inputs. Active current also excludes any DC load on the I/O pins.

Table 7-2. DC Characteristics – SPI Interface, RESET and GPIO PinsApplicable over the recommended operating range from T_A = -40°C to +125°C, V_CC = +2.7V to +5.5V.
Parameters	Test Conditions	Symbol	Min.	Typ.	Max.	Units	Type⁽¹⁾
Input Current⁽²⁾	0.1V_CC < Vi < 0.9V_CC	I_L	-2	—	+2	µA	A
Programmable Pull-Up	—	R_PU	24k	40k	62k	Ω	A
High-Level Output Voltage	I_OH = -4 mA	V_OH	V_CC – 0.4	—	—	V	A
Low-Level Output Voltage	I_OL = 4 mA	V_OL	—	—	0.4	V	A

Note:

Type means: A = 100% tested
This specification is only valid when the internal pull-ups are disabled. Otherwise, the input current is determined by the internal pull-up resistance value R_PU.

Parameters	Test Conditions	Symbol	Min.	Typ	Max.	Units	Type⁽¹⁾
Input Current⁽²⁾	0.1V_CC < Vi < 0.9V_CC	Ii	-10	—	+10	µA	A
Low-Level Output Voltage	I_OL = 20 mA V_CC > 3.6V to 5.5V	V_OL	0	—	0.4	V	B
Low-Level Output Voltage	I_OL = 14 mA V_CC = 2.7V to 3.6V	V_OL	0	—	0.4	V	B
Programmable Pull-Up	—	R_PU	2.3k	3.0k	4.5k	Ω	A

Note:

Type means: A = 100% tested, B = characterized on samples
The input current specification is only valid when the internal pull-ups are disabled. Otherwise, the input current is determined by the internal pull-up resistance value R_PU.
