AT32UC3A0256-ALUR

AT32UC3A0256-ALUR is the tape-and-reel ordering code for Microchip's AT32UC3A0256 AVR32 UC3 microcontroller in 144-pin LQFP — a 32-bit AVR32 core at 66 MHz with 256 KB Flash, 64 KB SRAM and 109 I/O, for production lines building industrial controllers and HMI units on the established UC3 platform. The reel form is the selection point of this code: identical silicon to the tray variant, packed for pick-and-place feeders, so the choice between this code and its sibling is made by your assembly process, not by the design. The device runs from a single 3.0 V to 3.6 V rail through its internal regulator and is rated -40 °C to +85 °C. Selection advice: quote this R code when your line consumes reels; for engineering lots or tray-fed assembly the same device is AT32UC3A0256-ALUT. If 256 KB Flash is more than the image needs, the AT32UC3A0128 codes offer the same package with 128 KB Flash and 32 KB SRAM. 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. Parameters verified against Microchip documentation.
