Atmel unleashes highest-performing ARM Cortex-M7-based MCUs

Atmel Corporation has launched four new series of devices to the Atmel | SMART ARM Cortex-M7 based MCUs. The new series delivers what the company claims are the industry's highest performing Cortex-M7-based MCUs, with exceptional memory and connectivity options for design flexibility. The new series is targeted for the automotive, IoT, and industrial connectivity markets.

All devices allow customers to scale-up performance and deliver SRAM and system functionality, while keeping the Cortex-M processor family ease-of-use and maximizing software reuse. The devices contain advanced memory architectures with up to 384KB of multi-port SRAM memory out of which 256KB can be configured as tightly coupled memory delivering zero wait state access at 300MHz. With over four times the performance of current Atmel ARM Cortex-M based MCUs running up to 300MHz, larger configurable SRAM up to 384kB and higher bandwidth peripherals, the new devices give designers the right connectivity, SRAM and performance mix for their industrial, connectivity and automotive designs. All devices come with high-speed USB On-the-Go (OTG) and on-chip high-speed USB PHY and Flash memory densities of 512kB, 1MB and 2MB.

Broadening the Atmel | SMART ARM Cortex-M based MCU portfolio, the new SAM E70 and the SAM S70 are targeted for connectivity and general purpose industrial applications, while the auto-grade SAM V70 and SAM V71 are designed for in-vehicle infotainment, audio amplifiers, telematics and head unit control.

Atmel’s SAM S70 series is based on the ARM Cortex-M7 core plus a floating point unit (FPU) extending the general purpose product portfolio with maximum operating speeds up to 300MHz, up to 2MB of Flash, dual 16KB of cache memory and up to 384KB of SRAM with an extensive peripheral set including high-speed USB host and device plus high-speed PHY, up to 8 UARTs, I2S, SD/MMC interface, a CMOS camera interface, system control and analog interfaces.

In addition to the SAM S70 series features, Atmel’s SAM E70 series include a 10/100 Ethernet MAC and Dual Bosch CAN-FD interfaces with advanced analog features making them ideal for connectivity applications. The SAM E70 is upwards compatible with Atmel’s SAM4E series.

The automotive-qualified SAM V70 and V71 series offer unique Ethernet AVB support, high-speed USB with integrated PHY and Media LB, which, when combined with the Cortex-M7 DSP extensions, make the series ideal for infotainment connectivity and audio applications. The series also offers the latest CAN 2.0 and CAN flexible data rate controller for higher bandwidth requirements.

Atmel is currently sampling the SAM E70, SAM S70, SAM V70 and SAM V71 series to select customers. General sampling for the SAM E70 and S70 series and the availability of the ATSAMV71-XULT Xplained kit is scheduled for February 2015. Pricing for the SAM S70 starts at $4.80 for 10k-piece quantities. Pricing for the Xplained board is USD $125.
