B4420NSE7QQMD

The B4420NSE7QQMD is a heterogeneous multicore microprocessor in NXP’s QorIQ Qonverge family combining Power Architecture and StarCore technologies. It integrates dual PowerPC e6500 64‑bit cores at up to 1.6 GHz alongside dual StarCore SC3900 FVP DSP subsystems to address compute‑intensive embedded and wireless base station workloads.

Designed for broadband wireless metro cell and wireless base station applications (including LTE, LTE‑Advanced, TD‑SCDMA and WCDMA), the device consolidates control, data‑path and application processing with hardware acceleration and data‑path offload to simplify board design and improve system integration.

Key Features

• Core & DSP  Two PowerPC e6500 64‑bit processor cores running up to 1.6 GHz plus two fully programmable StarCore SC3900 FVP core subsystems optimized for signal processing (SC3900 cores run up to 1.2 GHz as specified in product documentation).
• Memory & Cache  Integrated DDR3/DDR3L memory controller supporting up to 1866 MT/s and a 4.864 MB internal memory hierarchy: 32 KB L1 ICache and 32 KB L1 DCache per core, 2 MB L2 per cluster, and 512 KB shared L3 CoreNet platform cache.
• Hardware Acceleration  MAPLE‑B3 accelerators for forward error correction (Turbo/Viterbi), rate matching, MIMO MMSE equalization, FFT/iFFT/DFT, CRC and UMTS chip‑rate tasks; Data Path Acceleration Architecture (FMan/QMan/BMan) for packet parsing, queue and buffer offload.
• Security  On‑chip SEC 5.3 crypto engine with acceleration for IPsec, SSL and 802.16 and algorithm support listed in the specifications (AES, DES, 3DES, HMAC, IPsec, Kasumi, MD5, SHA‑1/2, SNOW‑3D, ZUC).
• High‑speed SerDes & Networking  Eight SerDes lanes supporting multi‑protocol connectivity: CPRI (up to 9.8 GT/s), Ethernet (1.0/2.5 GT/s), PCI Express (up to 5 GT/s) and debug (Aurora) lanes for glueless antenna and network interfaces. Four integrated Ethernet controllers (1/2.5 Gbps).
• Peripherals & Interfaces  USB 2.0 host/device support (1), I2C and a broad set of system peripherals including DMA and numerous 32‑bit timers (90) for system control and scheduling.
• Package & Mounting  Supplied in a 1020‑FCPBGA (33 mm × 33 mm) surface‑mount package, suited for compact, high‑density board implementations.
• Operating Range & Compliance  Consumer qualification with an operating temperature range of 0 °C to 105 °C and RoHS compliance.

Typical Applications

• Wireless Base Stations  Baseband and control plane processing for metro cell and small cell deployments, including LTE and LTE‑Advanced protocols where combined DSP and CPU processing is required.
• Broadband Wireless Infrastructure  Signal processing and data‑path acceleration for TD‑SCDMA and WCDMA systems, leveraging MAPLE‑B3 and SC3900 DSP subsystems for FEC and MIMO tasks.
• Embedded Network Appliances  Integrated networking, security acceleration and packet‑processing offload for specialized embedded routers, gateways and packet managers.

Unique Advantages

• Heterogeneous compute in one device: Combines high‑performance e6500 cores with StarCore DSP subsystems to consolidate control and signal processing tasks on a single SoC.
• Hardware acceleration for wireless algorithms: MAPLE‑B3 and dedicated accelerators reduce software burden for Turbo/Viterbi encoding/decoding, FFT/DFT and MIMO operations.
• Data‑path offload: FMan, QMan and BMan enable inline packet parsing and queue/buffer management to free CPU cycles for application processing.
• Comprehensive security: Integrated SEC 5.3 crypto engine with broad algorithm support helps meet protocol offload and throughput requirements without external accelerators.
• Flexible high‑speed I/O: Multi‑protocol SerDes lanes and multiple Ethernet controllers provide direct high‑speed links for radio, network and PCIe interfaces, simplifying board routing and connectivity.
• Compact, production‑ready package: 1020‑FCPBGA 33 mm × 33 mm package and surface‑mount mounting reduce BOM complexity for dense embedded designs.
