3.4.2 Power-Down Specification Limit (T_A = -40°C to 85°C)

A clarification for the power-down specification limit has been made. This clarification has corrections that are impractical to mark in bold. The following tables in this section contain the most current information and notes.

Table 3-5. ATmega329P DC Characteristics. T_A = -40°C to 85°C, V_CC = 1.8V to 5.5V (unless otherwise noted)
Symbol	Parameter	Condition	Min.	Typ.	Max.	Units
I_CC	Power supply current⁽¹⁾	Active 1 MHz, V_CC = 2V		0.5	0.75	mA
		Active 4 MHz, V_CC = 3V		2.6	3.5
		Active 8 MHz, V_CC = 5V		9.0	12.0
		Idle 1 MHz, V_CC = 2V		0.14	0.25
		Idle 4 MHz, V_CC = 3V		0.75	1.5
		Idle 8 MHz, V_CC = 5V		2.9	5.0
	Power-save mode⁽²⁾	32.768 kHz TOSC enabled, V_CC = 1.8V		0.75		µA
	Power-save mode⁽²⁾	32.768 kHz TOSC enabled, V_CC = 3V		1.0
	Power-down mode⁽²⁾	WDT enabled, V_CC = 3V		6.7	15.0
	Power-down mode⁽²⁾	WDT disabled, V_CC = 3V		0.2	2.0

Note:

All bits are set in the ‘Power Reduction Register’ on page 43.
Maximum and Typical values for 25°C. Maximum values are test limits in production.
