Highest-performing ARM Cortex-M7 based MCUs – claims Atmel

July 16, 2015 // By Graham Prophet
Targeting IoT and industrial markets, Atmel says its Atmel | SMART ARM Cortex-M7-based MCUs deliver 50% more performance than their closest competitor: the company has announced that it is in full production of the SMART SAM S70 and E70 series.

Atmel positions the MCUs as having larger configurable SRAM, larger embedded Flash and high-bandwidth peripherals, to offer connectivity, memory and performance. The SAM S70 and E70 series allow users to scale-up performance and deliver SRAM and system functionality, while keeping the Cortex-M processor family attributes and aiding software reuse.

The devices deliver over four times the performance of current Atmel | SMART ARM Cortex-M based MCUs. Running at up to 300 MHz and embedding larger configurable SRAM up to 384 kB and higher bandwidth peripherals, these devices offer designers connectivity, SRAM and peripherals for industrial and connectivity designs. The SAM S70 and E70 devices also offer advanced memory architectures with up to 384kB of multi-port SRAM memory out of which 256 kB can be configured as tightly coupled memory delivering zero wait state access at 300 MHz. All devices come with high-speed USB Host and Device with on-chip high-speed USB PHY and Flash memory densities of 512 kB, 1 MB and 2 MB.

These MCUs are supported by ARM ecosystem partners on development tools and real-time operating system (RTOS) board support packages (BSPs) accelerating time-to-market. Software development tools are available on Atmel Studio, the ARM Keil MDK-ARM and IAR Embedded Workbench. Operating system support include Express Logic ThreadX, FreeRTOS, Keil® RTX, NuttX and Segger embOS. A comprehensive set of peripheral driver examples and open source middleware is provided in Atmel’s Software Package.

To help accelerate a design, an Atmel Xplained development kit is available. Pricing for the SAM S70 starts at $5.34 in 64-pin LQFP package and 512 kB on-chip flash (10,000). The Atmel Xplained board is USD $136.25.
