The Microchip SAM V70 devices are a family of Automotive Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M7 processor with a Double Precision Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 1024 Kbytes of Flash, and up to 384 Kbytes of multi-port SRAM which is configurable Instruction and Data Tightly Couple Memories to leverage the advanced DSP capabilities of the core.

The SAM V70 series includes a HS USB Interface with integrated PHY, dual CAN-FD, QSPI, MediaLB, CMOS Imager interface, TDM/I2S (SSC,) multiple serial interfaces as well as on-board hardware cryptography including a TRNG, AES-256, and SHA-256 engines.

 

Automotive Production Devices

The ATSAMV70 family is AEC-Q100 Grade 2 qualified. The standard device does not go through the automotive production flow, and there are two options for ordering devices with the automotive production flow.

1) A customer specific part number will be assigned and designated with suffix to the base part number (i.e. ATSAMV70J20B-AABV02.)  A customer specific PPAP is available on request.

2) A generic suffix will be added to the base part number (i.e. ATSAMV70J20B-AABVA0.) A PPAP is unavailable for these devices.

Please contact your local Microchip sales representative for additional information.
