The SAM DA1 ARM® Cortex®-M0+ -based microcontrollers are operating at 48MHz (45DMIPS). The ATSAMDA1J15B provides 32KB Flash, 4kB SRAM and 1KB RWW Flash. The connectivity peripheral set consists of 6 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.
