Product details
Overview
SJA1110AEL/0Y from NXP Semiconductors is an automotive Ethernet switch IC with integrated 100BASE-T1 and 100BASE-TX PHYs, Arm® Cortex®-M7 core, functional safety features up to ASIL-D, TCAM-based packet inspection, and Wake-over-Ethernet (OPEN TC10) support-designed for gateway ECUs in vehicle networking systems.
For engineers reviewing the SJA1110AEL/0Y datasheet, SJA1110AEL/0Y pinout, SJA1110AEL/0Y application, or SJA1110AEL/0Y equivalent, key selection criteria include TSN/AVB protocol stack readiness, automotive Grade 1 temperature range (−40 °C to +125 °C), integrated secure boot, non-blocking switch core throughput, and compatibility with S32G processors and VR5510 PMIC.
Technical Context
The SJA1110AEL/0Y implements a non-blocking Ethernet switch core with hardware-accelerated Time-Sensitive Networking (TSN) and AVB protocols including 802.1AS gPTP synchronization, 802.1Qbv time-aware shaper, and 802.1Qci ingress policing. It integrates dual PHYs supporting 100BASE-T1 (automotive twisted-pair) and 100BASE-TX (legacy copper).
Its Arm Cortex-M7 subsystem runs production-grade AUTOSAR drivers and supports autonomous operation without host dependency; TCAM enables real-time frame inspection for intrusion detection/prevention (IDPS) and DoS mitigation, while TC10-compliant wake-up logic reduces ECU standby power consumption.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive Ethernet switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88Q5152 | Supports 1000BASE-T1 only; no integrated 100BASE-TX PHY or Arm Cortex-M7 subsystem; requires external MCU for TSN stack. | Lacks autonomous operation and secure boot-requires host-based firmware validation and external security IC for ASIL-B+ designs. | Preferred when cost-sensitive gateway designs use external 1 GbE PHYs and host MCU handles TSN scheduling. |
| Microchip LAN9668 | Offers 8-port 100BASE-T1 + 2×1000BASE-T1; no integrated TCAM or ASIL-D safety certification; uses MIPS core instead of Arm Cortex-M7. | No TC10 wake-up support or production-grade AUTOSAR drivers-limits suitability for OEM gateway platforms requiring full TC10 compliance. | Selected for mid-tier infotainment gateways where ASIL-D is not required and higher port count justifies added complexity. |
Compared with Marvell 88Q5152 and Microchip LAN9668, the SJA1110AEL/0Y uniquely combines ASIL-D readiness, integrated TCAM-based IDPS, autonomous operation, and native TC10 wake-up-making it the only single-chip solution qualified for safety-critical automotive gateway deployment without external safety monitors or security co-processors.

FAQ
What is the operating temperature range for the SJA1110AEL/0Y?
The SJA1110AEL/0Y is qualified for Automotive Grade 1 operation, spanning −40 °C to +125 °C ambient temperature. This rating applies to the full device-including integrated PHYs, switch core, and Cortex-M7 subsystem-and is validated per AEC-Q100 Grade 1 requirements. The SJA1110AEL/0Y maintains full functionality and timing specifications across this range without derating, enabling placement in engine bay or central gateway locations.
Does the SJA1110AEL/0Y support IEEE 802.1AS gPTP synchronization?
Yes, the SJA1110AEL/0Y provides hardware-accelerated IEEE 802.1AS-2020 gPTP synchronization with sub-1 µs timestamp accuracy. Its dedicated TSN timer and hardware timestamping engine operate independently of the Cortex-M7 core, ensuring deterministic latency. The SJA1110AEL/0Y supports both master and slave roles and integrates with NXP's production-grade gPTP middleware for seamless interoperability with S32G processors.
Is the SJA1110AEL/0Y pin-compatible with other variants in the SJA1110 family?
Yes, the SJA1110AEL/0Y shares identical 144-pin LFBGA package and pinout with SJA1110BEL/0Y, SJA1110CEL/0Y, and SJA1110DEL/0Y. All four variants are mechanically and electrically interchangeable on PCB-differences are limited to internal feature sets (e.g., number of enabled ports, TSN profile, and security options) configured via OTP fuses and firmware. No layout changes are required when migrating between SJA1110x variants.
What software support is provided for the SJA1110AEL/0Y?
NXP provides a production-grade Software Development Kit (SDK) for the SJA1110AEL/0Y, including AUTOSAR 4.3-compliant Ethernet drivers, Avnu-certified AVB/gPTP stack, Linux kernel drivers, and native integration with NXP Design Studio IDE.

All components are delivered with release notes, test reports, and safety manuals.
How does the SJA1110AEL/0Y implement Wake-over-Ethernet?
The SJA1110AEL/0Y implements OPEN Alliance TC10-compliant Wake-over-Ethernet using dedicated WAKE_N and TC10_WKUP pins. In deep-sleep mode, it draws <100 µA while monitoring link pulses and magic packets; valid TC10 wake frames trigger immediate full-power resumption within 100 µs. The SJA1110AEL/0Y validates frame structure and CRC before wake assertion, preventing spurious wake events from noise or malformed packets.
