ATMEL  ATSAME70N21A-AN  微控制器, 32位, SAM E系列, ARM Cortex-M7, 300 MHz, 2 MB, 384 KB, 100 引脚, LQFP

The is a SMART SAM E70 series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M7 RISC 5.04 CoreMark/MHz processor with floating point unit FPU. It operates at a maximum speed of 300MHz and feature up to 2048kB of flash, up to 384kB of multi-port SRAM and configurable instruction and data tightly couple memories to leverage the advanced DSP capabilities of the core. SAME70N21 features multiple networking/connectivity peripherals, including CAN-FD interface and one 10/100Mbps Ethernet MAC with specific hardware support for audio video bridging AVB. Additional communication interfaces include a HS USB host and device, a HS SDCard/SDIO/MMC interface, USARTs, SPIs and multiple TWIs. Analog features include dual 2Msps 12-bit ADCs with analog front end offering offset and gain error correction and 2Msps 12-bit DAC.
