NXP Semiconductors P1023NXE5CFB

Overview

P1023NXE5CFB from NXP Semiconductors (formerly Freescale) is a dual-core Power Architecture e500-v2 communications processor targeting enterprise WLAN, fixed routers, and security gateways. It operates at 500 MHz in dual-core mode or 800 MHz in single-core mode, integrates 256 KB L2 cache with ECC, supports DDR3/DDR3L memory, and delivers hardware-accelerated IPsec/SSL/TLS/802.1ae security processing.

For engineers reviewing the P1023NXE5CFB datasheet, P1023NXE5CFB pinout, P1023NXE5CFB application, or P1023NXE5CFB equivalent, key selection considerations include its dual e500-v2 cores, integrated DPAA data path acceleration, IEEE 1588 time-stamping support, MACSec offload, and 457-pin TEPBGA1 package compatibility with industrial temperature range (–40°C to +105°C).

Technical Context

The P1023NXE5CFB implements the QorIQ Data Path Acceleration Architecture (DPAA), enabling multi-core sharing of Ethernet interfaces and accelerators while reducing software overhead for packet classification, parsing, and forwarding. Its frontside coherent system bus interconnects CPU cores, L2 cache, memory controller, and accelerators including Frame Manager, Queue Manager, and Buffer Manager.

It features a programmable interrupt controller compliant with OpenPIC, four-channel DMA, dual 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII PHY interfaces, and three PCI Express 1.1 controllers multiplexed across four SerDes lanes up to 3.125 GHz - supporting wireless radio card connectivity via 802.11n/ac.

FAQ

What is the maximum operating frequency of the P1023NXE5CFB in dual-core mode?

The P1023NXE5CFB operates at a maximum of 500 MHz when both e500-v2 cores are active. This frequency is guaranteed across the full industrial temperature range (–40°C to +105°C) and supports deterministic real-time behavior for control-plane tasks while DPAA handles data-path acceleration independently.

Does the P1023NXE5CFB support DDR3L memory voltage?

Yes, the P1023NXE5CFB supports DDR3L memory at 1.35 V through its integrated 32-bit memory controller. This capability reduces system power consumption compared to standard DDR3 (1.5 V), making it suitable for thermally constrained fanless networking equipment where thermal design power must remain below 5 W.

Is IEEE 1588 hardware timestamping available on both Ethernet ports of the P1023NXE5CFB?

Yes, IEEE 1588 hardware timestamping is implemented on both 10/100/1000 Mbps Ethernet controllers of the P1023NXE5CFB. Timestamp registers capture ingress/egress packet times at the MAC layer with sub-microsecond resolution, enabling precise time synchronization for industrial Ethernet and telecom timing applications without software overhead.

Can the P1023NXE5CFB perform MACSec (IEEE 802.1ae) encryption and decryption in hardware?

Yes, the P1023NXE5CFB performs full MACSec (IEEE 802.1ae) encapsulation and decapsulation in hardware via its integrated Data Path Acceleration Architecture. This includes AES-GCM cipher suite execution, secure channel establishment, and replay protection - all without CPU involvement, ensuring line-rate 1 Gbps throughput with zero added latency.

What package type and pin count does the P1023NXE5CFB use?

The P1023NXE5CFB uses a 457-pin wirebond power-BGA package designated TEPBGA1 (27 mm × 27 mm, 1.0 mm pitch) with an exposed thermal pad. This package is qualified for industrial temperature operation and supports standard reflow profiles compatible with automated SMT assembly lines.
