SJA1105S
description
The SJA1105P/Q/R/S safe and secure automotive gigabit Ethernet switch family extends the capabilities of the SJA1105/SJA1105T [1] switches with improved security-related features
, extended interface options, and ISO 26262 ASIL-A pliance.
The SJA1105P/Q/R/S is a 5-port automotive Ethernet switch supporting IEEE Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards. Each of the five ports can be individually configured to operate at 10/100/1000 Mbit/s. This feature provides the flexibility to connect any Fast/Gigabit/optical PHY or MCU/MPU to any of the ports. Examples of external PHYs are the TJA1101, TJA1102 and TJA1103/4 100BASE-T1 PHYs and the TJA1120/21 1000BASE-T1 PHYs from NXP Semiconductors ([2] and [3]).
The new frame allow/denylisting, port-reachability and address learning restriction features
, available on all SJA1105P/Q/R/S variants, improve switch security by limiting data processing to known frames and data sources and preventing the...
