B4420NXN7QQMD

The B4420NXN7QQMD is an NXP QorIQ Qonverge heterogeneous multicore microprocessor SoC built around Power Architecture and StarCore technologies. It integrates dual e6500 64‑bit PowerPC cores at up to 1.6 GHz alongside dual SC3900 signal‑processing cores to address combined control, datapath and application processing needs.

Designed for broadband wireless metro cell deployments and general‑purpose embedded computing systems, the device targets wireless base station markets (including LTE and WCDMA). Its high integration density and on‑chip acceleration engines simplify board design while delivering application‑specific processing and packet/data‑path acceleration.

Key Features

• CPU Cores Dual PowerPC e6500 64‑bit cores running up to 1.6 GHz, paired with dual StarCore SC3900 FVP DSP subsystems optimized for signal processing workloads.
• Hardware Acceleration MAPLE‑B3 accelerator for forward error correction and PHY operations including Turbo/Viterbi algorithms, FFT/iFFT, MIMO MMSE equalization and related matrix operations.
• Data‑Path Acceleration Architecture (DPAA) Integrated Frame Manager (FMan), Queue Manager (QMan) and Buffer Manager (BMan) for in‑line packet parsing, classification, queue and buffer offload; Security engine (SEC 5.3) for crypto acceleration (IPsec, SSL, etc.).
• Memory Subsystem DDR3/DDR3L memory controller supporting up to 1866 MT/s and a large internal memory hierarchy including per‑core 32 KB L1 I/D caches, 2 MB L2 per cluster and 512 KB shared L3 CoreNet platform cache.
• High‑Speed SerDes and I/O Eight SerDes lanes with support for four CPRI lanes (up to 9.8 GT/s), four Ethernet lanes (1/2.5 Gb/s), PCIe lanes up to 5 GT/s and debug Aurora lanes, plus USB 2.0 and I2C.
• Security Features On‑chip crypto capabilities including AES, DES, 3DES, HMAC, IPsec, Kasumi, MD5, SHA‑1/2, SNOW‑3G and ZUC for secure communications and data handling.
• Packaging and Temperature 1020‑FCPBGA surface‑mount package (33 mm × 33 mm) with an operating temperature range of 0 °C to 105 °C; RoHS compliant.

Typical Applications

• Wireless Base Stations System consolidation for metro cell and small cell deployments handling PHY, MAC and control plane processing for LTE, LTE‑Advanced and WCDMA.
• Broadband Wireless Infrastructure Offloads FEC, FFT, MIMO and other radio processing with MAPLE‑B3 and SC3900 DSP cores while managing packet flows via DPAA components.
• Embedded Networking Platforms Packet classification, QoS and secure tunneling using FMan/QMan/BMan and the SEC 5.3 crypto engine for network and control applications.

Unique Advantages

• Heterogeneous Multicore Architecture: Combines PowerPC e6500 processors and StarCore DSP subsystems for flexible division of control and signal‑processing tasks.
• On‑Chip PHY and Algorithm Acceleration: MAPLE‑B3 provides dedicated hardware for common wireless algorithms, reducing software load and simplifying PHY implementation.
• Integrated Data‑Path Offload: DPAA components (FMan/QMan/BMan) offload packet and buffer management to improve throughput and deterministic behavior.
• Comprehensive Security Block: SEC 5.3 and supported crypto algorithms enable accelerated secure protocols such as IPsec and SSL without external accelerators.
• High‑Speed I/O Flexibility: Multiple SerDes lanes, Ethernet, PCIe and USB interfaces provide direct connectivity options for radio, backhaul and peripheral subsystems.
• Large On‑Chip Cache and Memory Support: Multi‑level cache architecture and DDR3/DDR3L support up to 1866 MT/s for demanding real‑time and throughput‑sensitive applications.
