Yep, that's a standard PLCC in a socket. Just as a quick tip, they are
often quite tight. I like to extract and replace 4-5 times with power off
on a new board just to 'break it in' so things go easy when hot swapping

One further caution, in spite of being keyed, it is fairly easy to insert
the chip backwards. Be sure to check it visually. If the chip heats up (it
will if backwards), pull power quickly.
