NXP Semiconductors P1011NSN2FFB

Overview

P1011NSN2FFB from NXP Semiconductors (formerly Freescale) is a single-core communications processor based on the Power Architecture e500 core, operating at 800 MHz with 32 KB L1 instruction and 32 KB L1 data cache per core, 256 KB configurable L2 cache with ECC, and three 10/100/1000 Mbps eTSEC Ethernet controllers. It targets multiservice gateways and Ethernet switch controllers under tight thermal constraints.

For engineers reviewing the P1011NSN2FFB datasheet, P1011NSN2FFB pinout, P1011NSN2FFB application, or P1011NSN2FFB equivalent, key selection criteria include its 689-pin TEPBGA2 package, DDR2/DDR3 memory controller with ECC, integrated security engine (SEC 3.3) supporting AES/RSA/SHA, IEEE 1588 time-stamping, and SerDes-configurable interfaces including two PCI Express lanes and two SGMII ports.

Technical Context

The P1011NSN2FFB implements a single e500v2 core with 36-bit physical addressing and double-precision floating-point support, paired with a coherency-capable L2 cache subsystem that can be partitioned, configured as SRAM, or used for stashing. Its on-chip network interconnect links the core complex to peripherals including eTSECs, USB 2.0 controllers, and eSDHC.

It integrates a 4-lane SerDes operating up to 3.125 GHz, multiplexed across two PCI Express 1.1 controllers and two SGMII interfaces, alongside a 32-bit DDR2/DDR3 SDRAM controller with ECC, programmable interrupt controller compliant with OpenPIC, and an enhanced local bus controller (eLBC) for legacy parallel memory and peripheral interfacing.

FAQ

What is the maximum supported DDR3 data rate for the P1011NSN2FFB?

The P1011NSN2FFB supports DDR3-800 (400 MHz clock, 800 MT/s) with a 32-bit bus width and full ECC capability. Its DDR controller implements on-die termination calibration and programmable read/write leveling to maintain signal integrity across temperature and voltage variations. This allows stable operation in industrial environments where memory bandwidth must remain consistent across –40°C to +105°C junction temperatures. The P1011NSN2FFB's DDR interface is fully compatible with JEDEC DDR3L-800 components.

Does the P1011NSN2FFB support IEEE 1588 Precision Time Protocol in hardware?

Yes, the P1011NSN2FFB includes dedicated IEEE 1588-2008 hardware timestamping logic within each of its three eTSEC controllers. It captures transmit and receive timestamps at the PHY/MAC boundary with sub-microsecond accuracy, supports one-step and two-step clock correction, and provides registers for fine-grained adjustment of delay asymmetry. This capability is enabled without CPU overhead and is validated in NXP's QorIQ SDK v1.5+ for PTP grandmaster and slave implementations. The P1011NSN2FFB's 1588 support meets ITU-T G.8265.1 requirements for telecom timing distribution.

Can the P1011NSN2FFB's L2 cache be used as general-purpose SRAM?

Yes, the P1011NSN2FFB's 256 KB L2 cache can be fully configured as lockable, non-cacheable SRAM via the L2CSR0 register. This mode disables cache coherency and allows direct byte-addressable access for firmware stacks, cryptographic key buffers, or real-time task data - eliminating cache-line conflict penalties. Configuration is persistent across resets and does not require MMU setup. This SRAM mode is documented in Section 12.4.2 of the QP10XXFS REV 6 reference manual and is used in secure boot sequences for the P1011NSN2FFB.

What SerDes protocols are supported by the P1011NSN2FFB's 4-lane SerDes?

The P1011NSN2FFB's 4-lane SerDes supports PCI Express 1.1 (Gen1), SGMII, and SATA I (1.5 Gbps) protocols - though SATA requires external PHY and is not enabled by default in production silicon. Each lane operates up to 3.125 GHz with programmable pre-emphasis and receiver equalization. The SerDes configuration is set at boot via RCW bits and cannot be dynamically reconfigured during runtime. The P1011NSN2FFB's SerDes does not support Serial RapidIO or CPRI.

Is the P1011NSN2FFB pin-compatible with the P1020 processor?

Yes, the P1011NSN2FFB is pin-compatible with the P1020 in the same 689-pin TEPBGA2 package. Both share identical power, ground, DDR, eTSEC, USB, and SerDes pinouts, enabling single-board designs to scale from single-core (P1011NSN2FFB) to dual-core (P1020) without PCB revision. However, the P1020 exposes additional debug and coherency signals not present on the P1011NSN2FFB, which remain NC on P1011NSN2FFB boards. This compatibility is explicitly confirmed in Table 1 of QP10XXFS REV 6.
