FAQ

What is the maximum DDR4 memory speed supported by the LX2162RE82029B?

The LX2162RE82029B supports DDR4 memory at up to 2.9 GT/s (DDR4-2933), implemented via a single 72-bit interface with full ECC protection across all 64 data bits and 8 ECC bits. This enables sustained bandwidth exceeding 23 GB/s in practical configurations, validated under JEDEC-compliant timing margins and NXP's recommended operating conditions.

Does the LX2162RE82029B support IEEE 1588 Precision Time Protocol in hardware?

Yes, the LX2162RE82029B integrates full hardware timestamping capability for IEEE 1588v2 across all 14 Ethernet MACs. Each MAC features dedicated timestamp registers, fine-resolution nanosecond counters, and hardware-assisted PTP event message handling-enabling sub-50 ns timestamp accuracy and deterministic delay measurement without CPU intervention.

How many PCIe Gen3 lanes does the LX2162RE82029B provide, and how are they configured?

The LX2162RE82029B provides three independent PCIe Gen3 controllers configured as x8, x4, and x4-totaling 16 usable lanes. These are electrically isolated and can be assigned to separate root complexes or endpoints, supporting mixed topologies such as NVMe storage (x4), FPGA acceleration (x8), and network adapter (x4) simultaneously without bandwidth contention.

Is CAN-FD support built into the LX2162RE82029B, and what data rates does it achieve?

Yes, the LX2162RE82029B includes two fully integrated Controller Area Network modules supporting CAN Flexible Data-Rate (CAN-FD) up to 5 Mbps in the data phase. Both controllers implement ISO 11898-1:2015 compliance, automatic bit rate switching, and hardware message filtering-enabling direct connection to automotive and industrial CAN-FD networks without external transceivers.

What security features are implemented in hardware on the LX2162RE82029B?

The LX2162RE82029B implements QorIQ Platform Trust Architecture 3.0 with ROM-based secure boot, hardware root-of-trust, tamper-detect circuitry, battery-backed security monitor, and 256 KB of dedicated on-chip RAM accessible only by trusted code. All cryptographic operations-including AES, SHA, RSA, and ECC-are accelerated in the SEC engine, with keys protected in hardware key stores.
