ATSAME70N20A-AN General Description

The Microchip SAME70N20 devices are members of a flash microcontrollers familybased on the high-performance 32-bit ARM Cortex-M7 processor with FloatingPoint Unit (FPU). These devices operate at up to 300MHz and feature up to 1024Kbytes of Flash, up to 384 Kbytes of multi-port SRAM and configurableInstruction and Data Tightly Couple Memories to leverage the advanced DSPcapabilities of the core. SAME70N20 features multiple networking/connectivityperipherals, including CAN-FD interface and one 1O/100Mbps Ethernet MAC withspecific hardware support for Audio Video Bridging (AVB). Additionalcommunication interfaces include a HS USB Host and Device, a HS SDCard/SDIO/MMCinterface, USARTs, SPIs and multiple TWIs. Analog features includes dual2Msps, 12-bit ADCs with analog front end offering offset and gain errorcorrection, and 2Msps 12-bit DAC.

The SAME70N20 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.
