ATSAMD21G18A-MU
Microchip TechnologyATSAMD21G18A-MU is a Microchip SAM D21 Arm Cortex-M0+ microcontroller in QFN-48 — for compact low-power embedded designs that need USB, SERCOM serial interfaces and capacitive touch in a small footprint. It provides 256 KB Flash, 32 KB SRAM, up to 48 MHz operation from 1.62 to 3.63 V, and the MU code denotes the QFN package in the −40 to +85 °C matte-Sn grade, supplied in tray. Selection advice: this QFN-48 part shares firmware with the TQFP-48 ATSAMD21G18A-AU but the footprints are not interchangeable, so confirm the package letter against your PCB before ordering. Ordering codes verified against the Microchip SAM D21 datasheet DS40001882, Table 3-4.
