NXP Semiconductors QorIQ® Layerscape LS1021A Communications Processor

NXP QorIQ® Layerscape LS1021A Communication Processors provide extensive integration and power efficiency for fanless, small form-factor enterprise networking applications. Incorporating dual Arm® Cortex®-A7 cores running up to 1.2GHz, the LS1021A processors are engineered to deliver CoreMark® performance of over 7,000. These processors also provide virtualization support, advanced security features, and the broadest array of high-speed interconnects and optimized peripheral features ever offered in a sub-3 W processor. The NXP QorIQ LS1021A processors feature an integrated LCD controller, CAN controller for implementing industrial protocols, DDR3L/4 running up to 1600 MHz, integrated security engine, and QUICC Engine®, and ECC protection on both L1 and L2 caches. The LS1021A processors are pin- and software-compatible with the QorIQ LS1020A and LS1022A processors.
