Maximum supply voltage RT1062 A0 silicon

[carstengroen]

Is it correct that the maximum supply voltage for DCDC_IN on the RT1062 (silicon A0) is 3.0V and not 3.6V ?

Its not mentioned in the datasheet or errata, but only in the Hardware Development Guide

So far everything seems to work without the magic smoke coming out :smileywink:

Running at 3.3V.

First program running, board is designed for testing of RT1064 which is not quite available yet, I mounted a RT1062 instead and made it possible to connect a Quad SPI Flash (at 0x60000000) to start testing.

Once I know this is 100% working as it should I will be able to save the CPU/SDRAM design/layout and use this in the subsequent "real projects".

Thanks for help so far :smileyhappy:

Board is a 4 layer 0.8 mm thick from JLCPCB (US$ 79,- incl DHL shipping. 8 days from gerber to PCB arrived at doorstep).

Hi Carsten

Hardware Development Guide gives references to silicon A0&3.0V

for i.MXRT1050, so seems this is not true for RT1062.

Thanks Igor,

so there is nothing that points to that the RT1062 (and RT1064) should not be able to use 3.3V for A0 silicon ?

The hardware development guide I mentioned is for both RT1050 and RT1060:

I will know in a week or so when PCB arrives here, then I will see what happens (I have the possibility to change LDO so I can use either 3.0 or 3.3V)

Hi Carsten

for supply voltage for DCDC_IN on the RT1062 one needs to use

its datasheet, it is prevalent over hardware development guide.

Thanks Igor,

will do :smileyhappy:
