ARMDevices.net explores the “world’s fastest ARM Cortex-M.”
Earlier this year, Atmel expanded upon its Atmel | SMART ARM-based microcontroller family with the launch of four new series of Cortex-M7 based devices, including the SAM S70 and E70 MCUs.
The new devices enable users to scale-up performance and deliver SRAM and system functionality, while keeping the Cortex-M family ease-of-use and maximizing software reuse. The MCUs 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 processors give designers the right connectivity, SRAM and performance mix for their industrial, connectivity and automotive designs.
In particular, the SAM S70 series is based on the 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.
Aside from the S70 series features, the recently-revealed SAM E70 also includes 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.
“All the series offer two Advanced Analog Frontend (AFE) with dual sample and hold capability and Up to 16-bit resolution with hardware oversampling. They also have programmable gain for small signal input. All series offer real-time event management through direct connection between PWM, Timer and ADC for motor control application,” ARMDevices.net writes. “Both series are based on the same feature set, the only difference is coming from the Ethernet, CAN support (SAME70 integrates Ethernet and CAN). Atmel offers all series in BGA and QFP from 64 to 144 pins. Small 64-pin pin count option offers an entry level form factor high performance MCU. All series support the extended Industrial temperature range from -40 to 105°C.”
