Difference between MCUXpresso and Datasheet on OPAMPs for MCX A365

[nxpenthusiast]

I am doing a project that needs 3 opamps on one MCU and selected the MXC A365 in the LQFP64 pin package. On the datasheet, it shows there should be 3 opamps. When I started doing peripheral assignment in MCUXpresso, it only lists OPAMP0 and OPAMP 2 as choices. There is no 3rd opamp choice. Is there a different way to enable the 3rd opamp or is the datasheet wrong? 

I've attached screen shots of the datasheet and what MCUXpresso shows.

Hello @nxpenthusiast ,

Thank you for bringing this issue to our attention. I’ve checked it, and there is indeed an inconsistency as you described. I’ll need to verify this internally, and I’ll keep you informed once I receive a confirmed answer.

Have a nice day.

Hello @nxpenthusiast ,

Thanks for your patience. I got the confirmation from the internal.

For LQFP64 package,

• MCXA34x/35x devices have 3 OPAMPs
• MCXA36x devices have 2 OPAMPs

Please refer to latest datasheet:

Mixed-signal Arm Cortex-M33 MCU with 180/240 MHz, up to 1024 KB Flash

Sorry for the inconvenience caused.
