The SAM DA1 ARM® Cortex®-M0+ -based microcontrollers are operating at 48MHz (45DMIPS). The ATSAMDA1E16B provides 64KB Flash, 8kB SRAM and 2KB RWW Flash. The peripheral set for connectivity consists of 4 serial communication modules (SERCOM) that each can be configured to act as a USART, UART, SPI and I²C. Additional connectivity options are provided by the on-chip one channel Inter-IC sound interface (I²S) and the full-speed USB 2.0 embedded host and device.

Supported by MPLAB X IDE and MPLAB Harmony.
