The Atmel® | SMART SAM V71 devices are members of a family of AutomotiveFlash microcontrollers based on the high-performance 32-bit ARM® Cortex®-M7processor with Floating Point Unit (FPU). These devices operate at up to300 MHz and feature up to 2048 Kbytes of Flash and up to 384 Kbytes of multiportSRAM. The on-chip SRAM can be configured as Tightly Coupled Memory(TCM) or system memory. A multi-port access to the SRAM guarantees aminimum access latency. The peripheral set includes an Ethernet MAC supporting IEEE1588, 802.1Qbb, 802.3az, 802.1AS and 802.1Qav, a high-speedUSB Device port and a high-speed USB Host port sharing an embeddedtransceiver, a MediaLB device interface, an Image Sensor Interface, a high-speedMCI for SDIO/SD/MMC, an External Bus Interface featuring an SDRAMController, and a Static Memory Controller providing connection to SRAM,PSRAM, NOR Flash, LCD module and NAND Flash. Additional peripheralsinclude three USARTs, five UARTs, three TWIs, one Quad I/O SPI, two SPIs, oneSSC, as well as two enhanced PWMs, twelve general-purpose 16-bit timers withstepper motor and quadrature decoder logic support, two CAN-FDs, one lowpowerRTT, one low-power RTC, two 12-bit ADCs, one 12-bit DAC and oneanalog comparator.
The SAM V71 devices have three software-selectable low-power modes: Sleep,Wait and Backup. In Sleep mode, the processor is stopped while all otherfunctions can be kept running. In Wait mode, all clocks and functions are stoppedbut some peripherals can be configured to wake up the...
