NXP Semiconductors P4080NSN7PNAC

Overview

P4080NSN7PNAC from NXP Semiconductors (formerly Freescale) is an eight-core Power Architecture® e500mc-based integrated communication processor with 2 MB L3 cache, dual 10-Gigabit Ethernet (XAUI), eight 1-Gigabit Ethernet controllers, and dual 64-bit DDR2/DDR3 memory controllers with ECC-designed for high-throughput control and data path processing in telecom/datacom routers and wireless infrastructure base station controllers.

For engineers reviewing the P4080NSN7PNAC datasheet, P4080NSN7PNAC pinout, P4080NSN7PNAC application, or P4080NSN7PNAC equivalent, key selection considerations include its CoreNet fabric coherence support, DPAA acceleration for packet classification and encryption (SEC 4.0), and FC-PBGA–1295 package thermal and power sequencing requirements.

Technical Context

The P4080NSN7PNAC implements a coherent CoreNet interconnect fabric linking eight independent e500mc cores, each with 128 KB L2 cache and ECC, plus a shared 2 MB frontside L3 cache with ECC. It integrates Data Path Acceleration Architecture (DPAA) comprising Frame Manager (FMan), Queue Manager (QMan), Buffer Manager (BMan), SEC 4.0 crypto engine, and PME 2.0 regex engine.

It supports two 10-GbE XAUI interfaces, eight 1-GbE controllers (via RGMII or SGMII), dual DDR2/DDR3 memory controllers with 64-bit bus width and ECC, three PCIe 2.0 ports, two serial RapidIO 1.2 ports, and multiple I/O peripherals including four I²C, four UART channels, and SD/MMC host controller-all managed via a multicore programmable interrupt controller (MPIC).

FAQ

What is the maximum DDR3 data rate supported by the P4080NSN7PNAC?

The P4080NSN7PNAC supports DDR3-1600 (800 MHz clock, 1600 MT/s) with both DDR controllers independently configurable. Each 64-bit channel delivers up to 12.8 GB/s peak bandwidth, validated under JEDEC specifications with on-die termination and write-leveling calibration sequences implemented in the boot ROM.

Does the P4080NSN7PNAC include hardware support for IEEE 1588 Precision Time Protocol?

Yes, the P4080NSN7PNAC includes full hardware timestamping for IEEE 1588v2 across all Ethernet interfaces (both 10-GbE XAUI and eight 1-GbE ports). Timestamp registers are accessible via memory-mapped CCSR space, and the TSEC modules support hardware-generated PPS pulses, alarm triggers, and 1588 clock synchronization signals.

How many SerDes lanes does the P4080NSN7PNAC provide, and what protocols do they support?

The P4080NSN7PNAC integrates an 18-lane Aurora SerDes block supporting XAUI (10-GbE), PCIe 2.0 (5 GT/s), serial RapidIO 1.2 (3.125 Gbps), and SATA II. Lane allocation is flexible: for example, two 8-lane groups for dual XAUI plus two lanes for PCIe reference clock, or one 8-lane sRIO link plus eight PCIe lanes and two spare lanes.

What boot sources are natively supported by the P4080NSN7PNAC?

The P4080NSN7PNAC supports boot from NOR flash (via eLBC), NAND flash (with BCH ECC), SD/MMC cards, and SPI flash (via eSPI). The internal BootROM implements secure boot with SHA-256 signature verification and AES-128 decryption, and allows configuration of primary/secondary boot devices through hardware strapping pins or fuses.

Is the P4080NSN7PNAC pin-compatible with other QorIQ P4 series processors like the P4081?

No, the P4080NSN7PNAC is not pin-compatible with the P4081. While both use the same 1295-ball FC-PBGA package, the P4081 de-featurizes one 10-GbE controller (FM1) and reassigns those SerDes lanes-resulting in different ball assignments for XAUI_RX/TX, PCIe, and sRIO signals. Board-level redesign is required for substitution.
