The SAM V series of Arm® Cortex®-M7 based automotive microcontrollers (MCUs) focuses on in-vehicle infotainment connectivity for audio amplifiers, telematic control units or head units. SAM V MCUs provide the best combination of connectivity interfaces—including Ethernet AVB, MediaLB, USB and CAN-FD— with the highest-performance Arm Cortex-M core that delivers up to 1500 CoreMarks®.

Key Features


  • High performance: Up to 1500 CoreMarks with the Arm Cortex-M7 core clocked at up to 300 MHz and coupled with unprecedented DSP performance
  • Advanced Memory Architecture: Up to 384 KB of multi-port memory out of which up to 256 KB can be assigned as Tightly Coupled Memory (TCM) for data and instructions, delivering 0 wait state at 300 MHz
  • Ethernet-AVB: The SAM V71 embeds an Ethernet MAC with specific hardware support for Audio Video Bridging (AVB); credit-based traffic shaping is implemented in hardware within the MAC to avoid involving the CPU
  • High Speed USB: Host and device mode High Speed USB controller with integrated PHY for reduced BOM cost
  • MOST® technology connectivity: 3-wire MediaLB® device interface provides seamless integration into a MOST network ring
  • Audio interfaces: Flexible TDM/I2S™ interfaces to connect audio sources, codecs or DSPs
  • CAN FD: Latest CAN 2.0 and CAN Flexible Data Rate (FD) controller for higher bandwidth
  • Automotive Grade: AEC-Q100 Grade 2 (−40°C to 105°C) qualified

SAM V70 MCUs

The SAM V70 family's peripheral set includes a High Speed USB device and host controller with integrated transceiver, a Quad SPI (QSPI) interface with Execute-In-Place (XIP) capabilities, a 3-wire MediaLB device interface, a high-speed Multimedia Card (MMC), a synchronous serial controller for TDM/I2S interfaces and a CMOS sensor interface.
