ATSAMDA1J14B-ABT Microchip 32bit MCU

ATSAMDA1J14B-ABT Overview

The SAM DA1 ARM® Cortex®-M0+ -based microcontrollers are operating at 48MHz (45DMIPS). The ATSAMDA1J14B provides 16KB Flash, 4kB SRAM and 512Byte 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.

Automotive Production DevicesThe ATSAMDA1 family is AEC-Q100 Grade 2 qualified. The standard device does not go through the automotive production flow, and there are two options for ordering devices with the automotive production flow.1) A customer specific part number will be assigned and designated with suffix to the base part number (i.e. ATSAMDA1J14B-MBTV02.) A customer specific PPAP is available on request.2) A generic suffix will be added to the base part number (i.e. ATSAMDA1J14B-MBTVA0.) A PPAP is unavailable for these devices.Please contact your local Microchip sales representative for additional information.

Supported by MPLAB X IDE and MPLAB Harmony.
