Product details
Overview
SJA1110BEL/0Y from NXP is an automotive Ethernet switch IC with integrated 100BASE-T1 and 100BASE-TX PHYs, Arm® Cortex®-M7 core, TCAM-based packet inspection, ASIL-D functional safety support, and Wake-over-Ethernet (OPEN TC10) - deployed in gateway ECUs for secure vehicle networking.
For engineers reviewing the SJA1110BEL/0Y datasheet, SJA1110BEL/0Y pinout, SJA1110BEL/0Y application, or SJA1110BEL/0Y equivalent, key selection criteria include TSN compliance (802.1AS/1Qbv/1CB), integrated secure boot, automotive Grade 1 temperature range (−40 °C to +125 °C), and native AUTOSAR driver support.
Technical Context
The SJA1110BEL/0Y implements a non-blocking switch core with hardware-accelerated AVB/TSN forwarding, supporting time-synchronized traffic scheduling via IEEE 802.1AS gPTP, 802.1Qbv time-aware shapers, and 802.1Qci ingress policing. It integrates dual PHYs (100BASE-T1 for automotive unshielded twisted pair and 100BASE-TX for legacy diagnostics).
Its Arm Cortex-M7 subsystem runs firmware for advanced frame inspection using a 128-entry TCAM, enabling real-time DoS prevention and IDPS offload. Functional safety features include lockstep CPU operation, memory ECC, and diagnostic coverage aligned with ISO 26262 ASIL-D requirements.

FAQ
What is the primary function of the SJA1110BEL/0Y in an automotive ECU?
The SJA1110BEL/0Y serves as a safety-certified, TSN-enabled Ethernet switch that routes and timesensitive traffic between automotive domains. It integrates dual PHYs, a Cortex-M7 subsystem for secure boot and packet inspection, and hardware-accelerated 802.1AS/1Qbv/1Qci - enabling deterministic communication in gateways and ADAS ECUs. Its role in the SJA1110BEL/0Y is foundational to secure, synchronized vehicle networking.
Does the SJA1110BEL/0Y support both 100BASE-T1 and 100BASE-TX simultaneously?
Yes, the SJA1110BEL/0Y integrates one dedicated 100BASE-T1 PHY and one dedicated 100BASE-TX PHY operating concurrently. This allows simultaneous connection to automotive sensors and actuators over single-pair cable (T1) and to legacy diagnostic tools or test equipment via standard RJ45 (TX). The SJA1110BEL/0Y manages both interfaces independently within its non-blocking switch fabric.
Is the SJA1110BEL/0Y qualified for ASIL-D functional safety compliance?
Yes, the SJA1110BEL/0Y is designed and documented to meet ISO 26262 ASIL-D requirements, including lockstep Cortex-M7 cores, ECC on all memories, safety mechanisms with >90% diagnostic coverage, and a published safety manual. It is intended for use in safety-critical automotive systems such as gateway and ADAS ECUs where SJA1110BEL/0Y deployment must satisfy full ASIL-D decomposition.
What TSN standards does the SJA1110BEL/0Y natively support in hardware?
The SJA1110BEL/0Y implements IEEE 802.1AS (gPTP), 802.1Qbv (time-aware shaper), and 802.1Qci (per-stream filtering and policing) in hardware. These capabilities enable precise time synchronization, scheduled traffic transmission, and ingress protection - all without host CPU involvement. The SJA1110BEL/0Y delivers sub-100 µs latency and jitter under 50 ns for time-critical applications.
Does the SJA1110BEL/0Y include production-grade AUTOSAR drivers?
Yes, NXP provides production-grade AUTOSAR-compliant Ethernet drivers and middleware for the SJA1110BEL/0Y, validated for use with AUTOSAR Classic Platform versions 4.3 and later. These drivers support standardized Ethernet COM, ETHIF, and TCP/IP stacks and are included in the official SJA1110 SDK.
