NXP Semiconductors P2020NXN2KHC

Overview

P2020NXN2KHC from NXP Semiconductors (formerly Freescale) is a dual-core Power Architecture e500-v2 communications processor operating at 1.2 GHz, featuring 512 KB L2 cache with ECC, 64-bit DDR2/DDR3 memory controller, and three 10/100/1000 Mbps Ethernet controllers with IEEE 1588 timestamping - deployed in telecom linecards for control plane processing under thermal constraints.

For engineers reviewing the P2020NXN2KHC datasheet, P2020NXN2KHC pinout, P2020NXN2KHC application, or P2020NXN2KHC equivalent, key selection factors include its dual-core e500-v2 architecture, 689-pin TEPBGA2 package, SerDes/PCIe/SRIO interface flexibility, integrated SEC 3.1 security engine, and support for industrial temperature range (–40 °C to +125 °C).

Technical Context

The P2020NXN2KHC implements two out-of-order, dual-issue e500-v2 cores with 36-bit physical addressing and double-precision floating-point units, sharing a coherent 512 KB L2 cache configurable as SRAM or stashing memory. It integrates a 64-bit DDR2/DDR3 memory controller with ECC and supports lossless flow control across three enhanced Ethernet MACs.

Its high-speed interconnect includes four SerDes lanes up to 3.125 GHz multiplexed across three PCIe v1.1 interfaces, two Serial RapidIO v1.2 links, two SGMII ports, and dual USB 2.0 controllers with ULPI PHY interface - enabling direct DSP coupling and backplane redundancy in LTE/WiMAX channel cards.

FAQ

What is the maximum operating junction temperature for the P2020NXN2KHC?

The P2020NXN2KHC is rated for a junction temperature range of –40 °C to +125 °C, validated per JEDEC JESD22-A104. This extended rating enables deployment in unheated outdoor telecom cabinets and sealed military vehicle enclosures where ambient temperatures exceed +85 °C. The P2020NXN2KHC thermal design must maintain case-to-ambient ΔT ≤ 35 °C under full load to stay within spec.

Does the P2020NXN2KHC support DDR3-1066 memory?

Yes, the P2020NXN2KHC's 64-bit DDR2/DDR3 memory controller supports DDR3-1066 (533 MHz) with 8-bit or 16-bit prefetch, full JEDEC compliance, and on-die termination control. It requires external DDR3 SDRAM modules with 256 Mbit–2 Gbit density and CL=7/8/9 timing. The P2020NXN2KHC does not support LPDDR3 or DDR4.

Is the security engine (SEC 3.1) enabled by default on the P2020NXN2KHC?

No, the SEC 3.1 block on the P2020NXN2KHC is optional and disabled at power-on reset. It must be explicitly enabled via the SEC configuration register (SEC_CFG) and initialized with cryptographic keys before use. The P2020NXN2KHC datasheet specifies that SEC 3.1 is present but not active until firmware writes to the security enable bit - ensuring no unintended crypto resource contention during boot.

Can the P2020NXN2KHC operate in asymmetric multiprocessing (AMP) mode?

Yes, the P2020NXN2KHC fully supports asymmetric multiprocessing (AMP) through its dual e500-v2 cores. Each core can run independent firmware images - for example, one core executing VxWorks for real-time control while the other runs Linux for management services. The P2020NXN2KHC provides separate interrupt vectors, cache partitioning controls, and memory-mapped mailbox registers to coordinate AMP tasks without OS interference.

What SerDes protocols are supported by the P2020NXN2KHC's four lanes?

The P2020NXN2KHC's four SerDes lanes support PCIe v1.1 (2.5 Gbps), Serial RapidIO v1.2 (1.25/2.5 Gbaud), SGMII (1.25 Gbps), and SATA I (1.5 Gbps) - configurable per lane via strap pins and RCW settings. It does not support CPRI, OBSAI, or 10GBASE-KR. Lane assignment is fixed: lanes 0–2 for PCIe/SRIO/SGMII, lane 3 for SGMII or SATA, with no dynamic reconfiguration after boot.
