NXP Semiconductors P1023NSN5CFB

Overview

P1023NSN5CFB 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, dual 10/100/1000 Mbps Ethernet controllers with IEEE 1588 timestamping and MACSec support, and a SEC 4.2 security engine for IPsec/SSL acceleration.

For engineers reviewing the P1023NSN5CFB datasheet, P1023NSN5CFB pinout, P1023NSN5CFB application, or P1023NSN5CFB equivalent, key selection criteria include dual-core e500-v2 performance, integrated DPAA data path acceleration, DDR3/DDR3L memory controller compatibility, SerDes lane allocation flexibility across PCIe/SGMII, and hardware-accelerated cryptographic throughput for IPsec/SSL/TLS.

Technical Context

The P1023NSN5CFB implements a coherent dual-core e500-v2 CPU complex with 36-bit physical addressing, double-precision floating-point units, and independent 32 KB I-Cache and 32 KB D-Cache per core. Its QorIQ Data Path Acceleration Architecture (DPAA) enables shared access to frame manager, parser/classifier, queue/buffer managers, and DMA across both cores-reducing software overhead for high-touch packet forwarding.

It features a 457-pin wirebond power-BGA (TEPBGA1) package with three PCI Express 1.1 controllers, two SGMII interfaces, four SerDes lanes up to 3.125 GHz, and a 32-bit DDR3/DDR3L memory controller supporting up to 1333 MT/s. The integrated security engine supports single-pass encryption/authentication for IPsec, SSL/TLS, SRTP, and DTLS using AES, RSA/ECC, SHA, and HMAC algorithms.

FAQ

What is the maximum operating frequency of the P1023NSN5CFB in dual-core mode?

The P1023NSN5CFB operates at a maximum of 500 MHz in dual-core mode, enabling balanced workload distribution across both e500-v2 cores while maintaining thermal efficiency. This frequency is specified under industrial temperature conditions (-40°C to +105°C) and requires compliant 1.0 V ±3% core supply regulation. The P1023NSN5CFB also supports 800 MHz single-core operation for peak burst performance.

Does the P1023NSN5CFB support IEEE 1588 Precision Time Protocol?

Yes, the P1023NSN5CFB supports IEEE 1588-2008 timestamping in hardware across both integrated 10/100/1000 Ethernet controllers. Each MAC includes dedicated timestamp registers and event capture logic, enabling sub-microsecond time synchronization accuracy when paired with compliant PHYs and software stack support-critical for industrial automation and telecom timing applications.

What memory technologies does the P1023NSN5CFB support?

The P1023NSN5CFB supports DDR3 and DDR3L SDRAM via its 32-bit memory controller, with data rates up to 1333 MT/s. DDR3L support enables 1.35 V operation for reduced power consumption in thermally constrained designs. The controller includes programmable timing parameters, on-die termination, and ECC support for system reliability-no DDR2 or LPDDR support is provided.

Can the P1023NSN5CFB perform MACSec (IEEE 802.1ae) encryption in hardware?

Yes, the P1023NSN5CFB performs full MACSec (IEEE 802.1ae) encapsulation and decapsulation in hardware through its integrated Ethernet MACs and DPAA frame manager. It supports AES-GCM-128 for confidentiality and integrity, with zero-copy offload from the security engine-enabling line-rate 1 Gbps MACSec processing without CPU involvement or software driver overhead.

Is the P1023NSN5CFB pin-compatible with other QorIQ P1 Series processors?

No, the P1023NSN5CFB is not pin-compatible with other QorIQ P1 Series processors such as the P1017 or P1022. While sharing the same TEPBGA1 package footprint (457-pin), pin assignments for SerDes lanes, PCIe reference clocks, and security engine interfaces differ significantly-requiring unique PCB layout and signal routing per variant. Board-level reuse is not supported.
