We are using MKL46Z256VLH4 for one of our projects. For this, We have provided 1.8V supply voltage for both VDD and VDDA. Its just near to minimum value. Hence the voltage level is 1.7V to 3.6V as per datasheet. We haven't used typical value like 2.5V or 3.0V or 3.3V.


We have to use 1.8V only because our interface IO levels are 1.8V compatible. Total current consumption of our board is 350mA(worst case). Will MKL46Z256VLH4 work with 1.8V supply?


Please reply as soon as possible. Thanks in advance.
