The Atmel | SMART SAM V71 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 300MHz and feature up to 2048 Kbytes of Flash, up to 384 Kbytes of multi-port SRAM and configurable Instruction and Data Tightly Couple Memories to leverage the advanced DSP capabilities of the core.

The SAM V71N21 is specifically designed for combining Ethernet-AVB and MediaLB connectivity along with advanced audio processing by leveraging the unique multi-port memory architecture and advanced Cortex-M7 DSP capabilities.

The peripheral set includes an Ethernet MAC supporting IEEE1588, 802.1Qbb, 802.3az, 802.1AS and 802.1Qav in hardware, a high-speed USB Device and Host controller with integrated transceiver, a Quad SPI interface with Execute-In-Place capabilities, a 3-wire MediaLB device interface, a High-Speed Multimedia Card, a Synchronous Serial Controller for TDM / I2S interfaces and CMOS Sensor interface.

Additional peripherals include two CAN-FD controllers, External Bus Interface with a Static Memory Controller, up to 10 channels 12-bit ADC, up to 2 channels DAC, 3 USARTs configurable as SPI, one dedicated SPI, 5 UARTs and up to 3 Two Wire Interfaces and up to 75 IOs.

Cryptographic signature and encryption is supported with True Random Number Generator, SHA-256 and AES-256 engines.

The ultra-low power backup domain allows to reach key-off requirements from car makers while being able to wake-up on a CAN message and retaining 1KB of SRAM critical data.

关键特性

  • High performance — Up to 1500 CoreMarks thanks to the Cortex-M7 clocked at up to 300MHz coupled with unprecedented DSP performance
  • Advanced Memory Architecture — Up to 384KB of multi-port memory out of which up to 256KB can be assigned as Tightly Coupled Memory (Data and Instructions) delivering 0 wait state at 300MHz
  • Ethernet-AVB — The SAM V71 embeds an Ethernet MAC with specific hardware support for Audio Video Bridging (AVB). Credit-based traffic shaping 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 connectivity — MediaLB 3-wire interface providing seamless integration into a MOST ring
  • Audio interfaces — Flexible TDM / I2S interfaces to connect audio sources, codecs or DSPs
  • CAN-FD — Latest CAN 2.0 and CAN Flexible Datarate (FD) controller for higher bandwidth
  • Automotive Grade — AEC-Q100 Grade 2 (-40C / 105C) qualified
  • Software Stacks — Autosar 4.x MCALs, BSW and OSEK. Communication stacks including Ethernet AVB
