RM44L520: rework on RM46x launchpad EVM

Part Number: RM44L520
Other Parts Discussed in Thread: RM46L852

Dear Champs,

As there is no specific EVM for RM44L520, my customer would like to rework on RM46x launchpad with RM44L520 144pin QFP package.

I could not see any issue in this case as these two devices are pin-to-pin compatible with same CPU voltages, but I would like to check it.

Could you please check if RM44L520 144pin QFP device can be rework on RM46x launchpad by replacing RM46L852?

What is the difference between RM44x series and RM46x? What is the difference between RM44L520 and RM46L852?

only differences are internal flash/ram size and ethernet ports?

Thanks and Best Regards,

SI.

  • Hi Sung-IL,

    There is no problem to replace RM46L852 on LP with RM44L452. They are pin-pin compatible.
