SAE J2716 Controller IP

Description and Features

SAE J2716 Controller interface provides full support for the SENT SAE J2716 synchronous serial interface, compatible with SENT specification SAE J2716 APR2016. Through its SAE J2716 compatibility, it provides a simple interface to a wide range of lowcost devices. SAE J2716 Controller IP is proven in FPGA environment. The host interface of the SAE J2716 can be simple interface or can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXILite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol. SAE J2716 Controller IP is supported natively in Verilog and VHDL
