NXP Semiconductors P4080NSE1PNB

Overview

P4080NSE1PNB from NXP Semiconductors (formerly Freescale) is an 8-core Power Architecture e500mc multicore processor operating up to 1.5 GHz, featuring dual 64-bit DDR2/DDR3 memory controllers with ECC, two 10 GbE XAUI interfaces, eight 1 GbE SGMII ports, and integrated datapath acceleration for packet parsing, classification, queue management, and SEC 4.0 cryptographic acceleration. It targets high-performance L2–L7 networking control and data plane processing in enterprise routers and LTE access gateways.

For engineers reviewing the P4080NSE1PNB datasheet, P4080NSE1PNB pinout, P4080NSE1PNB application, or P4080NSE1PNB equivalent, key selection considerations include its CoreNet coherency fabric bandwidth (800 Gb/s coherent read), hierarchical three-level cache (32 KB I/D L1 + 128 KB private L2 per core + 2 MB shared L3), and support for independent SMP/AMP core configuration with secure boot and hypervisor-enabled hardware partitioning.

Technical Context

The P4080NSE1PNB implements a scalable CoreNet coherency fabric enabling full cache coherency across eight e500mc cores, supporting prioritized and bandwidth-allocated coherent/non-coherent transactions between on-chip resources. Its datapath acceleration architecture integrates dedicated hardware blocks for packet parsing/classification/distribution, queue management with QoS scheduling, buffer allocation/de-allocation, and RegEx pattern matching via PME 2.0.

It features 18 lanes of 5 GHz SerDes supporting two 10 GbE XAUI, eight 1 GbE SGMII, three PCIe 2.0 controllers, two sRIO 1.2 controllers, and dual 64-bit DDR2/DDR3 memory controllers with interleaving and ECC - all managed through a unified peripheral access management unit (PAMU) and programmable interrupt controller.

Key Specifications

Pinout & Package

P4080NSE1PNB is housed in a 1296-pin FC-BGA package (37 mm × 37 mm, 1.0 mm pitch) with thermal lid and RoHS-compliant finish. Pin assignment follows the P4080-specific ball map defined in QP4080FS REV 4, supporting differential signaling for SerDes lanes, DDR DQS groups, and CoreNet fabric interconnects.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multicore communications processor applications.

Compared with P4080NSE1PNB, P4040NSE1PNB reduces core count and eliminates 10 GbE to cut power and cost, while P4081NSE1PNB retains 8-core topology at lower frequency and PCIe count - both preserve board compatibility but trade off peak throughput for targeted deployment constraints.

FAQ

What is the maximum operating frequency of the P4080NSE1PNB?

The P4080NSE1PNB operates at a maximum core frequency of 1.5 GHz. This rating is guaranteed across temperature and voltage corners per the QP4080FS REV 4 datasheet. All eight e500mc cores can sustain this frequency simultaneously when thermal and power delivery conditions are met. The P4080NSE1PNB uses dynamic voltage and frequency scaling (DVFS) to maintain stability under varying workloads, and its 45 nm process enables this performance within a 30 W TDP envelope.

Does the P4080NSE1PNB support DDR3 memory with ECC?

Yes, the P4080NSE1PNB integrates two 64-bit DDR2/DDR3 memory controllers with full ECC support, including single-bit error correction and double-bit error detection. Each controller supports registered and unbuffered DIMMs, with interleaving enabled across both channels to boost effective bandwidth. ECC functionality is configurable per memory region and enforced at the controller level - critical for telecom and industrial applications requiring high reliability. The P4080NSE1PNB's memory controller also supports JEDEC-standard DDR3-1600 timing parameters.

Is the P4080NSE1PNB pin-compatible with other P4 series processors?

Yes, the P4080NSE1PNB is pin-for-pin compatible with the P4040NSE1PNB and P4081NSE1PNB, sharing identical 1296-ball FC-BGA packaging, power delivery pinout, and SerDes lane assignments. This allows PCB reuse across variants. However, functional differences exist: the P4040 lacks 10 GbE XAUI and has only four cores, while the P4081 omits one PCIe controller and runs cores at 1.2 GHz. System firmware must be adapted to match the active peripherals on each variant.

What hardware security features does the P4080NSE1PNB include?

The P4080NSE1PNB includes SEC 4.0 cryptographic acceleration supporting AES-128/192/256, SHA-1/256, RSA-1024/2048, and DES/3DES, delivering up to 2.5 Gbps IPsec throughput. It also features a hardware random number generator (RNG), secure boot ROM with SHA-256/RSA-2048 signature verification, tamper-detect fuses, and Trust Architecture support for secure key storage and runtime attestation. These features are integral to the P4080NSE1PNB die and require no external security ICs for basic trusted boot and encrypted traffic processing.

Can the P4080NSE1PNB run multiple operating systems simultaneously?

Yes, the P4080NSE1PNB supports concurrent operation of multiple operating systems via its embedded hypervisor and hardware virtualization extensions. Each e500mc core can run a separate OS instance - such as Linux on some cores and VxWorks or bare-metal firmware on others - with strict memory and peripheral isolation enforced by the PAMU and CoreNet fabric. The hypervisor manages resource allocation, interrupt virtualization, and secure inter-VM communication. This capability is validated in the P4080NSE1PNB reference BSP and used in production RNC and secure gateway deployments.
