SAM V70
Atmel | SMART ARM-based Flash MCU
PRELIMINARY DATASHEET Description
The Atmel® | SMART SAM V70 devices are members of a family of Automotive 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, a MediaLB device interface, 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 lowpower RTC, two 12-bit ADCs, one 12-bit DAC and one analog comparator. The SAM V70 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. In addition, in this mode, the device is able to meet the most stringent Key-Off requirements while retaining 1Kbyte of SRAM and wake-up on CAN. 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 and Timer Counter. The Event System allows peripherals to receive, react to and send events in Active and Sleep modes without processor intervention. The SAM V70 devices are high-performance Automotive microcontrollers, targeting In-Vehicle Infotainment connectivity and audio amplifier applications, combining a rich set of interfaces and advanced DSP capabilities. SAM V70 devices operate from 1.62V to 3.6V and are available …
