P4040NSN7PNAC - QorIQ P4 4-Core 1.5GHz SoC | NXP Semiconductors
料号： P4040NSN7PNAC ✗ 停产P4040NSN7PNAC 概述
A QorIQ communications processor is a system-on-chip (SoC) designed by NXP (formerly Freescale) for wired and wireless infrastructure equipment. It sits in the product hierarchy: SoC -> communications processor -> multicore microprocessor -> PowerPC architecture -> embedded computing. The QorIQ P4 series was specifically engineered for routers, switches, base stations, and unified threat management (UTM) appliances where deterministic performance, hardware-accelerated packet processing, and high-throughput I/O are mandatory. Compared with single-core PowerQUICC predecessors, QorIQ platforms deliver multi-gigabit data-plane throughput while keeping power dissipation under 30 W.
The P4040NSN7PNAC integrates hardware datapath acceleration engines (DPAA), a security engine supporting IPsec, SSL, and Kasumi, an enhanced local bus controller, four I2C controllers, four UARTs, and integrated GPIO. It supports up to 8 GB of DDR3 memory with ECC for error-corrected high-availability operation. The 1.5 GHz core frequency and 32 KB I-cache / 32 KB D-cache per core plus 256 KB L2 per core provide deterministic throughput under network load.
Typical applications include multi-service routers, LTE/4G eNodeB baseband processing, enterprise switches with L4-L7 intelligence, network-attached storage (NAS) controllers, and industrial control platforms with deterministic Ethernet. The wide I/O suite (SRIO, PCIe Gen2, XAUI 10 GbE) makes the P4040 an ideal control-plane plus data-plane processor for compact telecom line cards.
When designing with this part, ensure the PCB has a minimum 8-layer stack-up with continuous GND planes beneath the FCPBGA, dedicated analog and digital supply domains, and a high-current VRM for the 1.0 V core rail. Thermal management is critical because the FCPBGA at full load dissipates up to 12 W and the 105 degrees C Tj requires a heatsink in air-cooled enclosures.

典型应用
P4040NSN7PNAC 适用于 6 应用s: Multi-Service Routers, LTE/4G eNodeB Baseband Processing, Enterprise L4-L7 Switches, Network-Attached Storage Controllers, Industrial Control Platforms, Unified Threat Management Appliances.
Multi-Service Routers
The P4040NSN7PNAC's four PowerPC e500mc cores at 1.5 GHz, two 10 Gbps XAUI Ethernet MACs and integrated IPsec engine make it a drop-in fit for multi-service router line cards. The DPAA datapath acceleration engine forwards packets at line rate without taxing the e500mc cores, while the security engine handles VPN termination on encrypted WAN links. Designers typically place the P4040 between a fan-out switch ASIC and the CPU complex, with DDR3-1600 ECC memory backing up routing tables. The 1295-FCPBGA package supports compact line-card form factors such as AMC and ATCA mezzanine modules.
推荐
LTE/4G eNodeB Baseband Processing
The P4040NSN7PNAC is well suited to LTE eNodeB baseband units where its SRIO links to DSP co-processors enable L1 acceleration offload, and the 10 GbE XAUI MAC connects to the backhaul network. With 1.5 GHz quad-core performance and integrated Kasumi/SNOW 3G cipher support, the SoC handles RRC, PDCP and RLC layers for small-cell and picocell deployments. The 0 to 105 C operating range supports outdoor radio units with appropriate heatsinking. Designers typically pair the P4040 with a TI TMS320C667x DSP for PHY processing via SRIO x4 link.
推荐
Enterprise L4-L7 Switches
The P4040NSN7PNAC's PCIe Gen2 controllers and two 10 GbE XAUI ports enable high-end enterprise switches that need wire-speed L4-L7 inspection. With four e500mc cores at 1.5 GHz and the integrated security engine for SSL inspection, the SoC can perform deep packet inspection at line rate on 10 Gbps uplinks. The DDR3-1600 ECC memory supports large flow tables and ACL databases without external TCAM. The 1295-FCPBGA's 37.5 x 37.5 mm footprint suits 1U and 2U rackmount switch designs.
推荐
Network-Attached Storage Controllers
The P4040NSN7PNAC powers mid-range NAS controllers where its PCIe Gen2 lanes connect to SATA/SAS RAID ASICs and the 10 GbE MACs aggregate iSCSI or NFS traffic. The quad-core performance handles RAID parity calculations and file-system operations, while the integrated security engine enables encrypted-at-rest storage using AES-256 and SHA-256. The 8 GB DDR3 ECC memory ceiling accommodates large ZFS or Btrfs caches. This part is also deployed in iSCSI SAN arrays where deterministic throughput is critical.
推荐
Industrial Control Platforms
The P4040NSN7PNAC delivers deterministic Ethernet and SRIO connectivity for industrial control platforms that require hard-real-time performance. Its quad-core architecture supports multiple isolated soft-PLC runtimes running on separate cores, while the hardware security engine signs control-plane messages for IEC 62443 compliance. The 0 to 105 C operating envelope supports factory-floor enclosures with heatsinking. Designers pair the SoC with a PHY like the NXP TJA1100 for deterministic Ethernet and an FPGA over SRIO for high-speed I/O.
推荐
Unified Threat Management Appliances
The P4040NSN7PNAC is deployed in unified threat management (UTM) appliances that combine firewall, IDS/IPS, VPN and content filtering in a single chassis. Its IPsec/SSL hardware engine handles encrypted traffic inspection at line rate on 10 GbE WAN links, while the four e500mc cores run user-space middleware and reporting. The integrated Kasumi engine supports 3G/4G mobile backhaul security. The DDR3-1600 ECC memory enables large malware signature databases to be cached on-chip for fast pattern matching.

关键差异点
- Quad-core 1.5 GHz with 32 KB + 256 KB L2 per core （对比 P1010NSN5DFB (single-core 1.0 GHz QorIQ P1))
- Integrated Kasumi / SNOW 3G cipher engine at line rate （对比 P4080NSN7MMC (8-core but same security engine))
- Dual 10 GbE XAUI plus eight 1 GbE MACs in single SoC （对比 P4040NSN1PNAC (1.2 GHz lower-speed variant))
设计说明
Estimated: at 1.5 GHz quad-core load with worst-case traffic, the P4040NSN7PNAC dissipates approximately 10 W into the 1295-FCPBGA package. With a typical theta_JB of 0.5 C/W to the top of the package and 0.8 C/W to the PCB, a 30x30 mm copper heatsink with thermal interface material is mandatory for operation above 25 C ambient. For fully outdoor telecom enclosures above 55 C ambient, force airflow of 200 LFM is required to keep Tj below 105 C.
The 1295-FCPBGA at 1.0 mm ball pitch requires a minimum 8-layer PCB stack-up with laser-drilled microvias (0.1 mm diameter) for inner-row breakout. Maintain a continuous GND plane on layer 2 directly beneath the BGA to control return-path impedance for the DDR3 and XAUI buses. Per the NXP hardware reference manual, place four 10 uF decoupling capacitors within 5 mm of the core-supply balls and use a 4-phase VRM for the 1.0 V VDD rail.
Do not assume the P4040NSN7PNAC is interchangeable with the P1010 or P2020 even though they share some QorIQ heritage: the boot ROM and pin-mux configuration differ between product lines, and a PCB designed for P2020 will not bring up a P4040 without rewiring the JTAG and reset pins. Always verify the NXP ordering code against the latest product change notice (PCN) before substituting EOL inventory. The NXP product page lists Discontinuance and Replacement information that must be reviewed.
The DDR3 interface supports speeds up to 1600 MT/s; route the byte lanes with matched impedance of 50 ohms +/-10 percent and length-matching within 25 mils across the byte group. Use fly-by topology for the address/command/control lines with the VTT termination at the far end. The XAUI 10 GbE lanes require AC-coupled capacitors at the transmit side per IEEE 802.3ae. Refer to the NXP hardware reference manual section on high-speed serial layout for the full set of routing rules.
合规信息
RoHS and REACH status not explicitly stated in the verified web data; lead-free is inferred from the BGA ball composition typical of FCPBGA packages shipped after 2006. AEC-Q100 is not applicable because this is a telecom-grade communications processor rather than an automotive MCU.
