ATSAMS70N21B-CN Overview

The MicrochipSAMS70N21 devices are members of a flash microcontrollers family based on the high-performance 32-bit ARM Cortex-M7 processor with Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 2048 Kbytes of Flash, up to 384 Kbytes of multi-port SRAM and configurable Instruction and Data Tightly Couple Memories to leverage the advanced DSP capabilities of the core. SAMS70N21 features multiple communication interfaces including 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.

The SAMS70N21 is available in 100-pin QFP and BGA package options.

Note: While there are no plans to change the availabilitystatus of Revision A for this device, new designs should use Revision B for prototypesand production. Supported by MPLAB X IDE and MPLAB Harmony.
