Atmel | SMART ARM-based Flash MCU
The Atmel ® | SMART SAM S70 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 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 generalpurpose 16-bit timers with stepper motor and quadrature decoder logic support, one low-power RTT, one low-power RTC, two 12-bit ADCs, one 12-bit DAC and one analog comparator. The SAM S70 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 SleepWalkingTM, 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. 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, ADC ...
