With a memory architecture optimised for real-time deterministic code execution and low latency peripheral data access, they are Auto-qualified Cortex-M7-based MCUs with Ethernet AVB and Media LB Peripheral capabilities for Automotive Connectivity and Audio Applications. Four series of devices allow users to scale-up performance and deliver SRAM and system functionality, while keeping the Cortex-M processor family ease-of-use and maximising software reuse. The devices contain advanced memory architectures with up to 384 kB 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. With over four times the performance of current Atmel ARM Cortex-M based MCUs running up to 300 MHz, larger configurable SRAM and higher bandwidth peripherals, they offer a connectivity, SRAM and performance mix for 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 512 kB, 1 MB and 2 MB.
Broadening the Atmel | SMART ARM Cortex-M based MCU portfolio, the new SAM E70 and the SAM S70 are suitable for connectivity and general purpose industrial applications, while the auto-grade SAM V70 and SAM V71 are ideal 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 300 MHz, up to 2 MB of Flash, dual 16 kB of cache memory and up to 384 kB 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 analogue interfaces.
The SAM E70 series include a 10/100 Ethernet MAC and Dual CAN-FD interfaces with advanced analogue features making them ideal for connectivity applications. The SAM E70 is upwards compatible with Atmel’s SAM4E series.
