NXP Semiconductors P1020NSN2DFB

Overview

P1020NSN2DFB from Freescale Semiconductor is a dual-core Power Architecture™ e500v2 integrated processor designed for networking and telecom control-plane/data-plane processing. It operates at up to 800 MHz, integrates 256 KB L2 cache with ECC, supports DDR2/DDR3 memory at 667 Mbps/pin, and features three enhanced 10/100/1000 Mbps Ethernet controllers (eTSECs) with IEEE 1588 support - deployed in WLAN access points and SMB gateways.

For engineers reviewing the P1020NSN2DFB datasheet, P1020NSN2DFB pinout, P1020NSN2DFB application, or P1020NSN2DFB equivalent, key selection criteria include dual-core SMP/AMP configurability, integrated security engine (SEC 3.3.2), PCI Express x1 ×2 root/endpoint flexibility, TDM interface for voice channel handling, and industrial temperature range (–40°C to 125°C) suitability for carrier-grade edge systems.

Technical Context

The P1020NSN2DFB implements two coherent e500v2 cores with 32 KB L1 I/D cache each and a shared 256 KB L2 cache configurable as SRAM or stashing memory. Its on-chip coherency module (ECM) maintains cache consistency between cores and I/O masters, while the 36-bit physical address map enables up to 4 GB DDR2/DDR3 memory addressing with ECC protection and page-mode optimization.

Three eTSECs provide hardware-accelerated TCP/IP v4/v6 header processing, VLAN/802.1Q tagging, jumbo frame support (9.6 KB), and IEEE 1588 timestamping via SGMII/RGMII interfaces. Dual PCI Express x1 lanes operate at 2.5 Gbaud per lane with boot-time root/endpoint configuration, and the integrated SEC 3.3.2 performs single-pass crypto operations (AES, SHA, RSA) for IPsec and SSL/TLS.

FAQ

What is the maximum DDR3 data rate supported by the P1020NSN2DFB?

The P1020NSN2DFB DDR2/DDR3 memory controller supports up to 667 Mbps per pin, corresponding to DDR3-1333 operation with appropriate timing parameters. This enables sustained memory bandwidth of 5.3 GB/s across the 32-bit bus, sufficient for dual-core packet buffering and crypto context storage in high-throughput networking applications. The P1020NSN2DFB also supports DDR2-800 and includes ECC for single-bit error correction.

Does the P1020NSN2DFB include an integrated security engine, and what algorithms does it support?

Yes, the P1020NSN2DFB includes the integrated Security Engine SEC 3.3.2, which supports AES (128/192/256-bit), DES/3DES, SHA-1/SHA-256, MD5, RSA (up to 4096-bit), ECC, and FIPS-compliant RNG. It performs single-pass cryptographic operations for IPsec, SSL/TLS, SRTP, and IEEE 802.11i, delivering up to 1.2 Gbps IPsec throughput without CPU involvement. The P1020NSN2DFB variant with SEC is confirmed in Freescale document P1020PB Rev. 0.

How many Ethernet controllers does the P1020NSN2DFB integrate, and what physical interfaces do they support?

The P1020NSN2DFB integrates three enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. They support RGMII, SGMII, and RMII physical interfaces - with eTSEC1 configurable for RGMII, eTSEC2 for SGMII, and eTSEC3 for RGMII or SGMII per Table 1 in P1020PB. All eTSECs implement IEEE 1588 timestamping, TCP/IP acceleration, and jumbo frames up to 9.6 KB.

What is the package type and thermal specification of the P1020NSN2DFB?

The P1020NSN2DFB uses a 31 mm × 31 mm, 689-pin Temperature-Enhanced Plastic BGA (TEPBGA II) package with 0.8 mm pitch and integrated thermal lid. It is rated for industrial operating junction temperature from –40°C to 125°C, validated per Freescale P1020PB Rev. 0 Section 2.2. This package supports standard reflow profiles and provides thermal resistance (θJA) of 12.5°C/W under typical board conditions.

Can the P1020NSN2DFB operate in symmetric multiprocessing (SMP) mode, and what OS support is available?

Yes, the P1020NSN2DFB dual e500v2 cores support symmetric multiprocessing (SMP) mode, enabling both cores to share memory and execute a single Linux kernel instance. Freescale provided SMP-enabled Linux BSPs and VxWorks support in the QorIQ SDK. Asymmetric multiprocessing (AMP) is also supported, allowing separate OS instances (e.g., Linux on one core, FreeRTOS on the other) - confirmed in Application Example 1.1 of P1020PB Rev. 0.
