VN8970

The Vector VN8970 is a plug-in module for the modular VN8900 interface family. It does not work on its own: it slides into a VN8900 base module, which supplies power and runs the real-time part of CANoe, CANalyzer or CANape. Vector's current manual lists the VN8911, VN8912A, VN8914 and VN8917 as base modules for it; the earlier manual also lists the VN8910A and VN8912.

The module has five piggyback slots and four built-in, isolated TJA1051 high-speed CAN transceivers. Slot 1 takes an FRpiggy for one FlexRay cluster (channels A and B) or a CAN/LIN piggyback, slots 2-4 take CAN, LIN or J1708 piggybacks, and channel 9 is reserved for an IO piggyback for digital and analog signals. Possible setups range from 1x FlexRay with 6x CAN to 8x CAN, or mixes of CAN and up to four LIN channels.

FlexRay uses a Bosch E-Ray controller in FPGA with a Fujitsu MB88121 startup controller and a 2 MB transmit buffer. CAN and CAN FD run on Vector's FPGA controller with full CANoe.CAN functions (error frames, bus load, listen-only), and LIN on a Vector controller compatible with LIN 1.3, 2.0, 2.1 and J2602. Applications include remaining bus simulation, gateways, test execution and bypassing. The VN8970 is still listed on Vector's VN8900 product page.
