Product Summary
The SAE81C91-N is a 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 of the SAE81C91-N 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.
Parametrics
SAE81C91-N absolute maximum ratings: (1)Ambient temperature under bias (TA): -40 to +110℃; (2)Storage temperature (TST): -50 to +150℃; (3)Voltage on VCC pins with respect to ground (VSS): -0.5 to +6.0V; (4)Voltage on any pin with respect to ground (VSS): -0.5 to VCC +0.5V; (5)Input current on any pin during overload condition: -10 to +10mA; (6)Absolute sum of all input currents during overload condition: ±100mA; (7)Power dissipation: 0.5W.
