ATSAMDA1G14B中文资料SAM 32-bit MCU数据手册Microchip规格书

描述 Description

The SAM DA1 ARM® Cortex®M0+ -based microcontrollers are operating at 48MHz (45DMIPS). The ATSAMDA1G14B 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.Supported by MPLAB X IDE and MPLAB Harmony.Functional SafetyThis device supports the ISO 26262 (ASIL B) functional safety standard.  ·   The Functional Safety Manual, FMEDA and information on the Diagnostic Software are available under NDA through the request form on the 32-bit Microcontrollers Functional Safety  web page.·  Learn more about  32-bit MCUs with Functional Safety capabilities including device hardware and certified software libraries.
