ATSAMD21E18A-MU

The ATSAMD21E18A-MU is a 32-bit SMART SAMD21 series Low-power Microcontroller based on the high-performance ARM Cortex-M0+ RISC processor. It operates at a maximum speed of 48MHz and features 256kB of flash memory and 32kB of SRAM. Peripherals include four serial communication modules (SERCOM) configurable as UART/USART, three 16-bit timers/counters, 32-bit real-time clock and calendar, 18 PWM channels, one 14-channel 12-bit ADC, one 10-bit DAC, full speed USB device and embedded host and support for up to 60 touch channels. The device operates from 1.62 to 3.63V.
