Embedded 32-bit MCU for LQFP64 designs

The AT32UC3B0256-A2UT is a 32-bit microcontroller supplied in a 64-pin LQFP package. It targets engineers developing embedded control firmware for industrial, automotive or consumer electronics. The device integrates 256 KB of on-chip flash memory for program storage.

No bundled software or accessories included

The component ships as a bare semiconductor without development boards, cables or licenced toolchains. Engineers must provide their own programming hardware and IDE. Projects needing pre-flashed firmware or evaluation kits will require separate procurement.

Questions about this item

What firmware updates or component swaps will the AT32UC3B0256-A2UT need during its service life?

The 32-bit MCU is mask-programmed at the factory; any functional change requires replacing the whole LQFP64 device on the board.

Which electrical limit is reached first when the AT32UC3B0256-A2UT runs continuously at full speed?

The 32-bit core draws maximum supply current at 256 KB flash access, so the package thermal rating is the first hard limit under sustained load.
