说明

基于SAM DA1 ARM®Cortex®-M0+的微控制器工作频率为48MHz（45DMIPS）。ATSAMDA1E16A提供64KB闪存，8kBSRAM和2KB RWW闪存。用于连接的外围设备由4个串行通信模块（SERCOM）组成，每个模块都可以配置为用作USART、UART、SPI和I^2.C.片上单声道IC间声音接口提供了额外的连接选项（I^2.S） 以及全速USB 2.0嵌入式主机和设备。

汽车生产设备
ATSAMDA1系列是AEC-Q100二级合格产品。标准设备不经过汽车生产流程，并且有两种选择可以通过汽车生产流程订购设备。

1） 客户特定的零件编号将被分配并指定为基础零件编号的后缀（即ATSAMDA1E16A-MBTV02。）客户特定的PPAP可根据要求提供。
2） 基本零件号（即ATSAMDA1E16A-MBTVA0）将添加通用后缀。PPAP不适用于这些设备。
