P2040NXN1FLB - QorIQ P2040 4-Core 667MHz e500mc MPU | NXP
The NXP P2040NXN1FLB is a quad-core PowerPC e500mc microprocessor in the QorIQ P2 communications processor family, delivering up to 667 MHz per core in a 780-pin FCPBGA (23x23 mm) package with industrial -40C to +105C temperature grade. Built on a low-power 45 nm process, it integrates four high-performance e500mc cores with 32 KB I-cache and 32 KB D-cache per core, plus a shared 256 KB CoreNet Platform Cache, making it suitable for demanding wired and wireless networking workloads. The device is the non-encryption, 667 MHz speed-grade variant of the P2040 family, targeted at cost-sensitive applications that do not require the on-chip SEC engine.
A communications processor is a system-on-chip (SoC) class microprocessor designed for packet processing, traffic management, and secure networking functions in routers, switches, base stations, and similar infrastructure. Within the broader taxonomy, it sits at the intersection of microprocessor (MPU), network processor, and embedded SoC. QorIQ P-series devices sit below the P3/P4/P5 high-end families but above the entry-level QorIQ LS series, and the P2040/P2041 pair bridges into the quad-core segment with the architectural heritage of the higher-tier P4080 platform.
Key differentiating features of the P2040NXN1FLB include four e500mc cores running at 667 MHz, a high-bandwidth CoreNet coherency fabric, three PCIe Gen 2 controllers, two 10 Gigabit Ethernet (XAUI) plus eight 1 Gigabit Ethernet (SGMII) MACs, four SerDes lanes configurable across multiple protocols, integrated security (without SEC engine in the NX variant), and a 32-bit DDR3 memory controller with ECC support. Hardware-accelerated queue and buffer management, pattern matching, and table lookup engines are also integrated for offloading common networking data-plane tasks.
Architecturally, the P2040 uses a coherency fabric connecting private L2 caches to a shared platform cache and to the I/O and memory subsystems, allowing all four cores to share data without software intervention. The e500mc core is a superscalar, out-of-order Power Architecture implementation with hardware virtualization support and a memory management unit that enables full Linux and VxWorks deployments. Integrated networking accelerators offload packet parsing, classification, and queue management, dramatically improving packets-per-second throughput versus general-purpose CPUs.
Typical applications include enterprise and SMB routers, unified threat management (UTM) appliances, wireless LAN controllers, multi-service access nodes, industrial control gateways, and single-board computers for networking infrastructure. The wide I/O mix (PCIe, XAUI, SGMII, USB, SATA, SDHC, SPI, I2C, UART, GPIO) and the dual-core / quad-core scalability make it a flexible choice for mid-range networking and industrial platforms.
When designing with this part, ensure the 780-pin FCPBGA package uses a high-layer-count PCB (typically 8+ layers) with controlled-impedance SerDes routing, matched-length DDR3 traces, and an adequate thermal solution. The 667 MHz NX speed-grade is the lowest-cost variant of the P2040; designers should choose the encrypted or higher-speed variants when SEC or higher throughput is required. Industrial temperature grade (-40C to +105C) supports harsh-environment deployments.
