The 2 MB Flash and 256 KB RAM give it the headroom to run an Ethernet stack, a graphical LCD controller, and a real-time control loop on the same die without external memory. The 100-LQFP package keeps the board area manageable for industrial or mid-complexity embedded designs.
The 82 I/O lines are enough to interface a parallel LCD plus a keypad or sensor array without a port expander.
Listed as Active with a current product status.
The two order codes share the same die, package, and electrical ratings. The only difference is the shipping medium: the TR suffix indicates Tape & Reel, while the base part number without TR typically ships in tray or tube. They are functionally identical and can replace each other in a BOM once the packaging format is accounted for.
