The 48-SSOP package (0.295" body width, 7.50 mm) is a fine-pitch SSOP — reworkable with hot air if the pad layout has adequate solder mask dams between pins. The Tape & Reel variant (TR suffix) is the standard for automated pick-and-place; the Cut Tape option suits prototype or low-volume builds.
The parallel NVSRAM family has been stable for years; no successor has been announced.
