ATSAMD20E16A-MU Description

Short technical summary and product information.

The ATSAMD20E16A-MU is a low-power, high-performance 32-bit microcontroller built around the ARM Cortex-M0+ core. It operates at up to 48 MHz and provides 64 KB of Flash program memory and 8 KB of SRAM. This device is part of the SAM D20 series and is intended for a wide range of embedded control applications.

 

Key electrical features include a wide supply voltage range of 1.62V to 3.6V, 26 general-purpose I/O pins, and connectivity options such as I²C, SPI, and UART/USART. On-chip peripherals include a 10-channel 12-bit ADC, a single 10-bit DAC, two analog comparators, and one timer. The microcontroller also integrates a brown-out detect/reset, power-on reset, and a watchdog timer.

 

The device is housed in a 32-VFQFN exposed pad package (5x5 mm, 0.95 mm height) and is specified for surface mount assembly. It is AEC-Q100 qualified, making it suitable for automotive environments. Operating temperature range is -40°C to +85°C. Compliance with RoHS3, REACH, and MSL level 1 is claimed but unverified.
