AT90USB1286-MU
by MICROCHIP(美国微芯)USB-connected embedded designs can use the AT90USB1286-MU, a Microchip AVR microcontroller with integrated USB functionality. It combines programmable control with a USB interface for applications such as custom peripherals and embedded equipment that communicates with a host. The MU part is represented here by a surface-mount QFN package with an exposed pad. The free KiCad download supplies a 65-pin symbol, the QFN-64_L9.0-W9.0-P0.50-BL-EP7.7 footprint with 65 pads, and a 3D model. These assets come from a real ProtoFlow import that was converted and checked in the editor. Open the microcontroller directly in ProtoFlow to start integrating it.
