Atmel Unleashes Highest-Performing ARM Cortex-M7-based MCUs with Superior Memory Architecture and Connectivity for Automotive, IoT and Industrial Markets

atmelAtmel announced the world’s highest-performing ARM® Cortex®-M-based microcontroller (MCU) with a 1500 CoreMark score. The new family of Atmel® | SMART™ ARM Cortex-M7-based MCUs is composed of four series: the SAM S70 general purpose, SAM E70 connectivity and SAM V70 and V71 automotive series.

Key Benefits

  • Extends Atmel | SMART MCU portfolio with the industry’s highest performing ARM Cortex-M-based MCUs (1500 CoreMark score)
  • Offers superior connectivity options and unique memory architecture optimized for real-time deterministic code execution and low latency peripheral data access.
  • Delivers industry’s first auto-qualified ARM Cortex-M7-based MCU with Ethernet AVB and media LB peripheral combination with DSP capabilities of the core for Automotive Connectivity and Audio applications

SAM S70 and E70 Devices

SAM S70 and E70 Devices 

SAM E70 series features Dual CAN-FD and Ethernet MAC – IEEE1588

SAM V70 and SAM V71 will be automotive qualified grade 2 (-40C / 105C)

SAM V71 series features Ethernet Audio Video Bridging (AVB) MAC

Atmel Software and Ecosystem

The new Atmel | SMART ARM Cortex-M7-based MCUs are supported by the following development tools:

  • IAR EWARM
  • ARM MDK
  • Atmel Studio
  • GNU tools for ARM embedded processors

Several market-leading RTOS solutions are being ported to the SAM S70 and E70 series

  • ARM, RTX
  • Segger, embOS
  • Express Logic, Thread-X
  • FreeRTOS
  • NuttX

The Atmel Software Package for the SAM S70 and E70 series includes a complete set of peripheral driver examples, facilitates board bring up and testing for the hardware designer, complements the datasheet for the software programmer to optimize software for the target device and facilitates software porting from previous MCUs.

Source code for the software package is available under Atmel SAM Software Package license, which offers source code reuse for commercial purposes without any publication obligation.

The Software Package includes a set of open source middleware that can be easily ported on an RTOS or bare metal software platform

  • High Speed USB device
    • Class drivers: Audio, CDC, HID, mass storage, PHDC
    • Support for composite devices
  • High Speed USB mini host stack
    • Class drivers: CDC, HID, mass storage
  • Ethernet
    • lwip – Lightweight TCP/IP stack
    • uIP – Micro IP TC/IP stack
  • Storage (file system)
    • fatfs – FAT file system (NAND Flash, SD card, eMMC card, on-chip Flash)
  • JPEG encoder & decoder

AUTOSAR 4.0 (MCALs, OSEK and Communication stacks) is being ported to the SAM V70 and V71 automotive series.

A complete Automotive Ethernet Audio Video Bridging (AVB) stack is being ported to the SAM V71 series.

An ATSAMV71-XULT full-featured Xplained Ultra board covers all four series of Atmel | SMART ARM Cortex-M7-based MCUs

Target Applications

Broadening the Atmel | SMART ARM Cortex-M-based MCU portfolio, the new SAM E70 and the SAM S70 series devices are ideal for connectivity and general-purpose industrial, consumer and IoT applications, while the auto-grade SAM V70 and SAM V71 devices are ideal for in-vehicle infotainment connectivity, audio amplifiers, telematics and head control units companion device.
