CAN FD Supported by 32-bit Microcontrollers

Microchip offers a broad product portfolio for our 32-Bit MCUs with integrated CAN FD BUS compliant to 11898-1:2015 (ISO CAN FD.) These products range from entry level devices to high performance products both in industrial and automotive qualified solutions.

Our entry level solutions include the Dual ISO CAN FD SAMC21 which ranges from a 32-Pin to 64-Pin device with up to 256 KB of Flash, 32 KB of SRAM, and 8 KB for EEPROM emulation. The SAMC21 integrates a wide range of peripherals. An automotive qualified version of the SAMC21 is planned with many of the same features.

Our high-performance solutions include up to two ISO CAN FD interfaces. The SAME70, SAMV70, and SAMV71 offer performance up to 300 MHz and 600 DMIPs. Package options are available from 64-pin to 144-pin with 512 KB-2 MB of Flash and 256K-384K of SRAM. The SAME70, SAMV70, and SAMV71 include advanced features with a 10/100 Ethernet with IEEE1588 and Ethernet AVB support, Tightly Coupled Memory (TCM,) as well as High Speed USB. The SAMV70 and SAMV71 are automotive qualified versions.

Both the entry level solution and high performance devices are supported with Atmel Studio 7 (integrated development platform) and Atmel Start (online tool graphical configuration tool for embedded projects.) Code examples and lower level peripheral drivers are included.
