Freescale Completes First Generation of QorIQ Qonverge Base Station-on-Chip Portfolio with New Metrocell Product

Multimode B4420 SoC, built on highly advanced Power Architecture® and StarCore technologies, delivers optimal performance, throughput and capacity

SAN ANTONIO — (BUSINESS WIRE) — June 18, 2012 — With the addition of a metrocell system-on-chip (SoC) solution to its QorIQ Qonverge line, Freescale Semiconductor (NYSE: FSL) is delivering the industry’s first base station-on-chip portfolio built on a common architecture that scales from small to large cells. Freescale’s new QorIQ Qonverge B4420 baseband processor offers high throughput, simultaneous multimode operation for up to 250 users and support for the LTE, LTE Advanced and WCDMA (HSPA+) standards.

The B4420 completes the first generation of Freescale’s QorIQ Qonverge portfolio, which already includes SoCs for small cell and multi-sector macrocell base stations. The processor is designed for high-capacity metropolitan areas and enhanced outdoor coverage where macrocell coverage is insufficient. The B4420 offers optimal coverage for end users and gives operators enhanced radio planning flexibility and ultra-high performance while reducing capital and operating expenditures.

“Our first generation of QorIQ Qonverge base station-on-chip devices will help transform the future of wireless infrastructure equipment, delivering the technology required to help ramp up LTE, while reducing cost and future-proofing new WCDMA deployments,” said Scott Aylor, general manager of Freescale’s Wireless Access Division. “Our new B4420 baseband processors give base station OEMs access to the industry’s most scalable single-chip solutions for feature-rich micro- and metro-carrier deployed base stations.”

The metrocell B4420 SoC shares a common architecture and is software-compatible with the small cell and macrocell members of the QorIQ Qonverge portfolio, and it is package- and pin-compatible with the QorIQ Qonverge B4860 device. This extensive compatibility helps OEMs speed time to market and leverage their software and hardware investments.

The B4420 device delivers a leap in performance by integrating two dual-threaded Power Architecture® e6500 processor cores running at 1.6 GHz and two StarCore digital signal processor (DSP) SC3900 flexible vector processor cores running at 1.2 GHz, along with the ultra-high performance Multi-Accelerator Platform Engine for Baseband (MAPLE-B) for Layer-1 acceleration, and accelerators for Layer-2 and transport processing. Built on 28-nm process technology, the B4420 provides up to two 20 MHz LTE sectors, 600 Mbps of throughput and relay support with optimal power/cost ratios, allowing designers to develop base stations with high user density, low cost and low-power design.

The B4420 base station-on-chip is designed to help operators accommodate rapid adoption of 4G data-centric wireless devices, while reducing costs associated with 3G deployments. It provides a comprehensive high-performance/cost-effective processing solution that supports Layer-1 to transport baseband processing, from backhaul IP packets to antenna IQ samples. High-speed, industry-standard interfaces provide antenna, Wi-Fi® chipset and backhaul glueless connectivity.

Proven technology and industry-leading cores

The QorIQ Qonverge base station-on-chip portfolio is built on two proven technologies.

  • The Power Architecture e6500 dual-thread core achieved the industry’s highest CoreMark® benchmark performance per watt profile, enabling development of small base stations with high user density and low-power operation.
  • Freescale’s newest StarCore DSP core, the SC3900, which recently earned the highest fixed-point BDTIsimMark2000™ benchmark score ever recorded by independent signal-processing technology analysis firm Berkeley Design Technology, Inc. (BDTI) 1, provides nearly 2x higher DSP performance compared to competitive offerings. Delivering 1.2 GHz and 32 MACs of 16-bit per cycle, the DSP cores allow OEMs to develop a high-throughput system while leveraging their own IP using the programmable cores, all within optimal cost and power thresholds.

Enablement tools and software

Freescale offers a rich ecosystem of products and services to support the B4420 family, including the CodeWarrior integrated development environment (IDE) based on Eclipse technology to provide a comprehensive multicore development environment. Available tools include the QorIQ Qonverge development system (QDS) board, C-optimizing compilers for Power Architecture and StarCore architectures, as well as profilers and debuggers for visibility into source code execution. In addition, Freescale’s partner network offers highly efficient DSP and MPU operating systems with BSPs and optimized device drivers.


Freescale plans to offer samples of QorIQ Qonverge B4420 devices in Q3 2012. For more information, visit
