SAM E70
Atmel | SMART ARM-based Flash MCU
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 multi-
port 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 (GMAC) supporting AVB,
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 (ISI), a high-speed Multimedia Card Interface (HSMCI)
for SDIO/SD/e.MMC, an External Bus Interface (EBI) 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 Universal Synchronous Asynchronous Receiver Transmitters
(USART), five Universal Asynchronous Receiver Transmitters (UART), three
Two-wire Interfaces (TWI) supporting the I2C protocol, one Quad I/O Serial
Peripheral Interface (QSPI), two Serial Peripheral Interfaces (SPI), one Serial
Synchronous Controller (SSC) supporting I2S and TDM protocols, as well as two
enhanced Pulse Width Modulators (PWM), twelve general-purpose 16-bit timers
with stepper motor and quadrature decoder logic support, two Controller Area
Networks with Flexible Data Rate (CAN-FD), one ultra low-power Real-Time
Timer (RTT), one ultra low-power Real-Time Clock (RTC), dual Analog Front-End
(AFE) including a 12-bit Analog-to-Digital Converter (ADC), a Programmable Gain
Amplifier (PGA), dual Sample-and-Hold and a digital averaging with up to 16-bit
resolution, dual-channel 12-bit Digital-to-Analog Converter (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
predefined conditions. This feature, called SleepWalking™, performs a partial
asynchronous wake-up, thus allowing the processor to wake up only when
needed. In Backup mode, RTT, RTC and wake-up logic are running. Optionally a
1-Kbyte low-power SRAM can be retained.
To optimize power consumption, the clock system has been designed to support
different clock frequencies for selected peripherals. Moreover, the processor and
bus clock frequency can be modified without affecting processing on, for example,
the USB, U(S)ART, AFE and Timer Counter.
