AT32UC3A0128-ALUT

AT32UC3A0128-ALUT is the tray ordering code for Microchip's AT32UC3A0128 AVR32 UC3 microcontroller in 144-pin LQFP — a 32-bit AVR32 core at 66 MHz with 128 KB Flash, 32 KB SRAM and 109 I/O, for cost-trimmed industrial control designs that stay on the UC3 platform without paying for memory they never use. Against the 0256 variant on this site, only the memory map shrinks: the package, pin count, core speed and I/O count are the same, so an existing UC3A board design carries over and the firmware image size becomes the deciding factor. The device runs from a single 3.0 V to 3.6 V rail through its internal regulator, over -40 °C to +85 °C. Selection advice: the final T is tray packing — the reel form of this device is AT32UC3A0128-ALUR; measure your production firmware against the 128 KB Flash before choosing, because stepping up later means the 0256 code, not a different board. Our checks found no discontinuation notice for this series; we confirm the offered lot against your requirements before quoting. The code appeared in a cecb2b buy request for 3,000 pieces.
