Freescale debuts first ARM-based QorIQ LS series communications processors

Freescale Semiconductor has unveiled its new QorIQ LS1 family of communications processors based on the core-agnostic, software-aware Layerscape system architecture. The devices are engineered to support a broad range of power-sensitive networking applications, as well as additional fast-growing product categories including Internet of Things gateways and industrial automation and control equipment.

Each of the three new QorIQ LS1 family processors features two reliability-optimised ARM Cortex-A7 cores. These efficient cores – typically used in battery-powered applications such as smartphones – have been enhanced with error detection and correction technology. Pre-silicon analysis by Freescale indicates the dual Cortex-A7 cores should achieve over 6,000 CoreMarks of performance at 1 GHz, with typical power at under 3 W for the entire SoC.

“Market demand is growing for high-performance solutions suitable for fanless, sub-3 W designs,” said Tareq Bustami, vice president of Product Management for Freescale’s Digital Networking business.

In addition to its power efficiency, the QorIQ LS1 family also provides impressive levels of integration for a processor in the sub-3 W power envelope. The LS1 family incorporates an optimised blend of peripherals and features for fanless embedded applications, including: LCD controller, ECC protection of all SRAM for maximum reliability, support for both DDR3L and DDR4 memory, virtualization support, QUICC Engine technology, SATA3 and USB 3.0 with integrated PHY, all packed into a small 19x19mm SoC footprint.

The pin- and software-compatible LS1 family includes three products:

· The highly integrated QorIQ LS1020A processor which is suitable for fanless enterprise and consumer networking applications, such as enterprise access points, multi-protocol IoT gateways and security appliances

· The QorIQ LS1021A processor, which adds integrated display controller and industrial interfaces for use in factory/building automation, M2M, printing and defense/aerospace applications

· The cost-optimised QorIQ LS1022A processor, which is intended to offer high-reliability performance for the most power-sensitive industrial applications with extremely aggressive power envelopes

According to Freescale its networking experience combined with ARM’s ecosystem will give designers access to comprehensive tools to ease development. The QorIQ LS1 family is supported by Freescale’s Tower System modular development platform, featuring an integrated on-board probe for further cost savings, along with third-party platforms developed by Freescale’s embedded board solutions partners.
