Introduction

The Siemens Stand Alone Full CAN (SFCAN) circuit incorporates all the parts for completely autonomous transmission and reception of messages using the CAN protocol. The flexible, programmable interface allows hookup to different implementations of the physical layer. The link to a host controller can be made either by a multiplexed 8-bit address/data bus or by a high-speed, serial synchronous interface.

Stand Alone
