MCP2517FD
In Production
The MCP2517FD is a cost-effective and small-footprint External CAN FD Controller that can be easily added to a microcontroller with an available SPI interface. Therefore, a CAN FD channel can be easily added to a microcontroller that is either lacking a CAN FD peripheral or that doesn't have enough CAN FD channels.
特性
Conforms to ISO11898-1:2015
Supports both CAN 2.0B and CAN FD
Arbitration Bit Rate up to 1 Mbps
Data Bit Rate up to 8 Mbps
Up to 20MHz SPI Clock Speed
31 FIFOs configurable as transmit or receive
32 Flexible Filter and Mask Objects
One Transmit Queue
32-bit Time Stamp
Bus Health Diagnostics and Error Counters
VDD: 2.7V-5.5V
Active Current Max: 12mA @ 5.5V, 40 MHz CAN Clock
Sleep Current: 10uA, Typical
Temperature Range: -40C to +150C
Packages: VDFN14 (Wettable Flanks), SOIC14
外置的CAN-FD控制器可以看看NXP有没有。。。。
NXP看了一遍,都是CAN的收发器,有带CAN-FD的MCU,这样又得换平台了。
Microchip CAN FD结尾的都支持FD CAN
多谢,看了看都是收发器。
CAN 的发展 正是日新月异,都 10MBPS了,我们还在玩1Mbps的

是的。
必须得can-fd
