POWER_ON_BASE: 

During some power down states, the 3.3V areas of the CPU module will be switched off. In this case 
all the peripheral chips which are connected to 3.3V referenced signals have to be switched off, 
too. Otherwise the CPU will be back-powered via the I/O pins. 

The signal POWER_ON_BASE can be used to control a DC/DC converter or a mosfet to switch the 
3.3V on the baseboard on and off. Example schematics are available. 

POWERFAIL# 

The signal POWERFAIL# is an input to signalize a power fail condition. A low will trigger an 
interrupt, e.g. to safe data.  

ON_OFF# & WAKEUP: 

The signals ON-OFF# and Wakeup are used to control the PMIC so it gets up from power down 
states. 

BAT: 

The emCON BAT pin is the battery input pin for the RTC power supply. The typical power 
consumption of the RTC via the BAT pin is < 1µA. 

4.21.2

 

Power Consumption 

A benchmark document [3] from NXP provides measurements and detailed information about the 
power consumption of the i.MX8MM processor itself.
