The Atmel | SMART SAME70J21 devices are members of a flash microcontrollers family 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. SAME70J21 features multiple networking/connectivity peripherals, including CAN-FD interface and one 1O/100Mbps Ethernet MAC with specific hardware support for Audio Video Bridging (AVB). Additional communication interfaces include a FS USB Host and Device, USARTs, SPIs and multiple TWIs. Analog features include single 2Msps 12-bit ADCs with analog front end offering offset and gain error correction, and 2Msps 12-bit DAC. The SAME70J21 is available in 64-pin QFP package options.

Principais recursos

  • High Performance architecture — ARM Cortex-M7 core-based MCU running at 300MHz with integrated FPU. 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. Accelerate execution from on-chip Flash, NVM connected to Quad SPI and EBI with 16KB of data and 16KB of instruction cache memory.
  • Comprehensive peripheral set for connectivity — 10/100Mbps Ethernet-AVB MAC with traffic shaping, CAN-FD, Full-Speed USB Host and Device with integrated PHY, camera interface, a full range of high-speed serial peripherals for fast data transfer.
  • Advanced analog — Single 2Msps, 12-bit ADCs with analog front end, offering offset error correction and gain control. Also includes 2Msps 12-bit DAC.
  • Security — Include encrypted Quad SPI bus on the fly, tamper detection pins and secure data storage, hardware encryption engines supporting AES, as well as secures Hash Algorithm (SHA) and finally integrates True Random Number Generator (TRNG).
  • Design support — Reduce development time and cost with Atmel Studio integrated development platform, which includes Atmel Software Framework, a complete library of source code, project examples, drivers and stacks
