SAM E70
Atmel | SMART ARM-based Flash MCU
PRELIMINARY DATASHEET Description
The Atmel ® | SMART SAM E70 devices are members of a family of Flash
microcontrollers based on the high-performance 32-bit ARM ® Cortex ® -M7
processor with Floating Point Unit (FPU). These devices operate at up to
300 MHz and feature up to 2048 Kbytes of Flash and up to 384 Kbytes of multiport SRAM. The on-chip SRAM can be configured as Tightly Coupled Memory
(TCM) or system memory. A multi-port access to the SRAM guarantees a
minimum access latency. The peripheral set includes an Ethernet MAC
supporting IEEE1588, 802.1Qbb, 802.3az, 802.1AS and 802.1Qav, a high-speed
USB Device port and a high-speed USB Host port sharing an embedded
transceiver, an Image Sensor Interface, a high-speed MCI for SDIO/SD/MMC, an
External Bus Interface featuring an SDRAM Controller, and a Static Memory
Controller providing connection to SRAM, PSRAM, NOR Flash, LCD module and
NAND Flash. Additional peripherals include three USARTs, five UARTs, three
TWIs, one Quad I/O SPI, two SPIs, one SSC, as well as two enhanced PWMs,
twelve general-purpose 16-bit timers with stepper motor and quadrature decoder
logic support, two CAN-FDs, one low-power RTT, one low-power RTC, two 12-bit
ADCs, one 12-bit DAC and one analog comparator.
The SAM E70 devices have three software-selectable low-power modes: Sleep,
Wait and Backup. In Sleep mode, the processor is stopped while all other
functions can be kept running. In Wait mode, all clocks and functions are stopped
but some peripherals can be configured to wake up the system based on
