NXP Semiconductors P1011NSE2DFB

Overview

P1011NSE2DFB from NXP Semiconductors (formerly Freescale) is a single-core Power Architecture e500 communications processor operating at 800 MHz, featuring 32 KB L1 instruction and data caches per core, 256 KB L2 cache with ECC, and integrated triple 10/100/1000 Mbps Ethernet controllers with IEEE 1588 timestamping-designed for multiservice gateways and Ethernet switch controllers under tight thermal constraints.

For engineers reviewing the P1011NSE2DFB datasheet, P1011NSE2DFB pinout, P1011NSE2DFB application, or P1011NSE2DFB equivalent, key selection considerations include its 689-pin TEPBGA2 package, DDR2/DDR3 memory controller with ECC, integrated security engine (SEC 3.3) supporting AES/RSA/SHA, and SerDes-configurable dual PCI Express and dual SGMII interfaces.

Technical Context

The P1011NSE2DFB implements a single e500v2 core with 36-bit physical addressing and double-precision floating-point support, paired with a coherency-capable 256 KB L2 cache configurable as SRAM or stashing memory. Its on-chip network interconnect links three eTSECs, a 4-lane SerDes, and dual PCIe controllers.

It integrates a full SEC 3.3 cryptographic engine enabling single-pass IPsec/SSL packet processing, alongside a 32-bit DDR2/DDR3 SDRAM controller with ECC and an enhanced local bus controller (eLBC) for legacy parallel memory and peripherals-targeting deterministic control-plane and lightweight data-plane workloads.

FAQ

What is the maximum supported DDR3 speed for the P1011NSE2DFB?

The P1011NSE2DFB supports DDR3-800 (400 MHz clock, 800 MT/s data rate) with 32-bit bus width and on-die termination control. Its DDR controller implements automatic read/write leveling and per-byte write calibration to ensure signal integrity across industrial temperature ranges. The P1011NSE2DFB datasheet specifies tRCD, tRP, and tRAS timing parameters compliant with JEDEC DDR3-800 standards.

Does the P1011NSE2DFB support IEEE 1588 Precision Time Protocol in hardware?

Yes, the P1011NSE2DFB includes dedicated IEEE 1588 v2 hardware timestamping logic in all three eTSEC controllers. Each eTSEC provides sub-100 ns timestamp resolution on both transmit and receive paths, with hardware-assisted PTP frame parsing and correction field updates-enabling transparent clock and boundary clock implementations without CPU intervention.

Can the P1011NSE2DFB's L2 cache be used as general-purpose SRAM?

Yes, the P1011NSE2DFB's 256 KB L2 cache can be configured as lockable SRAM via the L2SRAMCR register. This mode disables cache coherency and allows direct byte-addressable access for real-time stacks, crypto buffers, or DMA descriptor tables-retaining ECC protection and deterministic latency, unlike external SRAM.

What SerDes protocols are supported by the P1011NSE2DFB's 4-lane engine?

The P1011NSE2DFB's 4-lane SerDes supports PCIe 1.1 (2.5 Gbps per lane), SGMII (1.25 Gbps), and SATA I (1.5 Gbps) protocols. Lane allocation is fixed per configuration: lanes 0–1 for PCIe, lanes 2–3 for SGMII-or all four lanes for quad-SGMII. It does not support Serial RapidIO or CPRI on this device.

Is the P1011NSE2DFB pin-compatible with the P1020 series?

Yes, the P1011NSE2DFB is fully pin-compatible with the P1020 series (e.g., P1022NSE2DFB) in the same 689-pin TEPBGA2 package. Shared pinout enables single PCB design reuse across single-core and dual-core variants, with identical power, clock, DDR, and peripheral signal assignments-only core count and certain L2 coherency signals differ functionally.
