MCUs feature up to 384KB of multi-port SRAM memory

The devices allow customers to scale-up performance and deliver SRAM and system functionality, while maintaining the Cortex-M processor family ease-of-use and maximising software reuse. The MCUs feature up to 384KB of multi-port SRAM memory, 256KB of which can be configured as tightly coupled memory delivering zero wait state access at 300MHz. Enabling designers the necessary connectivity, SRAM and performance for their industrial, connectivity and automotive designs, the devices provide 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 MCUs are offered with high-speed USB On-the-Go and on-chip high-speed USB PHY and Flash memory densities of 512kB and 1 and 2MB.

The SAM E70 and the SAM S70 are suitable for connectivity and general purpose industrial applications. Based on the ARM Cortex-M7 core and a floating point unit, the SAM S70 series feature operating speeds of up to 300MHz, up to 2MB of Flash, dual 16KB of cache memory and up to 384KB of SRAM. The MCUs are also offered with an extensive peripheral set, including high-speed USB host and device plus high-speed PHY, up to eight UARTs, I2S, an SD/MMC interface, a CMOS camera interface, and system control and analogue interfaces. In addition to the SAM S70 features, Atmel’s SAM E70 series includes a 10/100 Ethernet MAC and Dual CAN-FD interfaces with advanced analogue features. The SAM E70 is upwards compatible with Atmel’s SAM4E series.

The auto-grade SAM V70 and SAM V71 are suitable for in-vehicle infotainment, audio amplifiers, telematics and head unit control. The devices feature Ethernet AVB support and Media LB, which, when combined with the Cortex-M7 DSP extensions, make the MCUs suitable for infotainment connectivity and audio applications. For higher bandwidth requirements, the devices are offered with the latest CAN 2.0 and CAN flexible data rate controller.

“As one of the first ARM licensees, we are excited to be among the first suppliers to introduce a portfolio of ARM Cortex-M7-based MCUs,” commented Jacko Wilbrink, Senior Marketing Director, Atmel. “Our family of Cortex-M7-based devices broaden the Atmel | SMART Cortex-M-based MCUs and provide a robust feature set tailored for the automotive, industrial, consumer and IoT markets giving designers the next level of performance, along with advanced high-speed connectivity, high density on-chip memory and a solid ecosystem to meet every designer’s needs. We look forward to seeing more applications in the market adopt our Cortex M7-based devices.”

“Atmel was a lead partner for the ARM Cortex-M7 processor launch in October 2014 and the milestone of shipping automotive-qualified SoCs demonstrates significant progress,” said Richard York, Vice President, Embedded Marketing, ARM. “Atmel’s broad family of Cortex-M7 based MPUs provide high performance, advanced connectivity, flexible memory options and a solid ecosystem tailored for the automotive, industrial and general connectivity markets.”

The SAM E70, SAM S70, SAM V70 and SAM V71 are currently sampling to select customers. General sampling for the SAM E70 and S70 series is scheduled for February 2015. The SAM S70 MCUs are priced from $4.80 and sold in 10,000 piece-quantities.
