Plug-in card

M.2 expansion card with CAN FD

Published 2017-10-26

According to Peak-System (Germany), the PCAN-M.2 is the first M.2 PCIe card connectable to Classical CAN and CAN FD networks.

The M.2 plug-in card can support dataphase bit-rates of up to 12 Mbit/s. The board uses an 80-MHz oscillator, for the 12-Mbit/s transmission a clock rate of 60-MHz is used to optimize the bit-timing. The implemented Microchip transceiver is qualified by the manufacturer for 8 Mbit/s. The CAN FD protocol allows payloads up to 64 byte. The card can be connected to Classical CAN and CAN FD networks via a 9-pin D-Sub connector using the pin-assignment as recommended in CiA 303-1. Each CAN FD channel can be terminated and is galvanic decoupled with 300 V. The module is available as single- and dual-channel version. The extended operating temperature ranges from -40 °C to +85 °C.

For a future-proof operational capability, the card complies with the M.2 size 2280 over the common contact strip with B and M key and a predetermined breaking point. The latter makes it possible to adjust the length from 80 mm to 60 mm, corresponding to the M.2 size 2260. Furthermore, the product can be used arbitrarily on current mainboard sizes such as Mini-ITX up to E-ATX. Thus, the CAN FD card is positioned for small as well as large desktop and industrial PC housings, said the company. It is particularly suitable for embedded systems used in motor vehicles, trains, and aircrafts.

The scope of delivery includes the application PCAN-View for the display of Classical CAN and CAN FD traffic. Several APIs (application programming interfaces) and device drivers for Windows and Linux are also part of it.
