3.2 Electrical Characteristics – T_A = -40°C to 105°C

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

Table 29-1. ATmega164PA DC Characteristics. T_A = -40°C to 105°C, V_CC = 1.8V to 5.5V (unless otherwise noted)


Symbol	Parameter	Condition	Max.	Units
I_CC	Power supply current⁽¹⁾	Active 1 MHz, V_CC = 2V	0.7	mA
		Active 4 MHz, V_CC = 3V	3
		Active 8 MHz, V_CC = 5V	11
		Idle 1 MHz, V_CC = 2V	0.17
		Idle 4 MHz, V_CC = 3V	0.85
		Idle 8 MHz, V_CC = 5V	6
	Power-down mode⁽²⁾	WDT enabled, V_CC = 3V	15	µA
	Power-down mode⁽²⁾	WDT disabled, V_CC = 3V	5	µA

Note:

All bits set in the ‘PRR0 – Power Reduction Register 0’ on page 56 in the data sheet.
Maximum and Typical values for 25°C. Maximum values are test limits in production.
