Part Number: TM4C1232H6PM
Other Parts Discussed in Thread: TM4C123GH6PM,

 I am refreshing a working design that uses the latter part. I would consider the former if it's drop in or an easy port.

    Hi,

    It depends on your application. These two part numbers have slightly different peripheral sets on CAN, I2C and USB. For example, in TM4C123GH6PM , it has 2 CAN modules while TM4C1232H6PM only has 1. If your application is currently using 2 CAN modules then you will have a compatibility issue despite these two devices have the same memory size. Same for USB. TM4C123GH6PM supports Host/Device/OTG while TM4C1232H6PM only supports Device mode. The pinouts for the USB is different between the two devices.

    Please use the below product selection guide for selection.

    Thank you so much. I did a search for a Tiva C selection guide before asking my question, but for some reason did not find it.
