개요

Description

ATSAMD21E15B-AUT is Microchip/Atmel’s 32-bit SAM D21 microcontroller. It uses an ARM Cortex-M0+ core, runs up to about 48 MHz, and is designed for low‑power embedded applications. It provides multiple SERCOM peripherals (USART/SPI/I2C), USB full‑speed device support, a 12‑bit ADC (and other analog features on some variants), timers, and flexible I/O. The “E15B” part code plus the “-AUT” suffix denote the exact memory map, package type, voltage range and temperature/qualification variant; the precise flash/RAM sizes, package (e.g., QFN/TQFP), and operating temperature are specified in the datasheet. Typical uses include USB devices, sensors, IoT nodes, and compact control applications where performance and low power are important. For exact specs, consult the Microchip SAM D21E15B datasheet and product pages.
