Product details

It runs at 80MHz, carries 512KB of Flash program memory and 64KB of RAM, and provides 46 general-purpose I/O lines. The part is supplied in a 108-ball LFBGA package (10x10 mm) and operates over -40°C to 85°C on a 3.3V supply rail.

512 KB Flash + 64 KB RAM — firmware budget and BOM fit

512KB of Flash and 64KB of RAM are on-chip.

Obsolete — sourcing path and lifecycle reality

Package and mounting — board-fit note

The 108-ball LFBGA (10x10 mm) requires a standard BGA reflow profile. All 46 I/O are routed to the ball grid; no exposed pad for thermal relief.
