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 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 (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. Atmel-11296C-ATARM-SAM E70-Datasheet_19-Jun-15 The SAM E70 devices also feature an event system that allows peripherals to receive, react to and send events in Active and Sleep modes without processor intervention. The SAM E70 devices are high-performance general-purpose microcontrollers with a rich set of connectivity peripherals and large memory integration. This enables the SAM E70 to sustain a wide range of applications including consumer, industrial control, and PC peripherals. SAM E70 devices operate from 1.7V to 3.6V and are available in the following packages: ̶ 144-pin LQFP ̶ 144-ball LFBGA ̶ 100-pin LQFP ̶ 100-ball TFBGA ̶ 64-pin LQFP The SAM E70 devices are pin-to-pin compatible with the SAM4E (100-pin and 144-pin versions), except for USB signals. The Atmel application note “Migrating the SAM4E to SAM E70 Microcontroller” (reference 44034) is available on www.atmel.com to ease migration from SAM4E devices to SAM E70 devices.
