LS1021ASN7HNB

The QorIQ LS1 family, which includes the LS1021A communications processor, is built on Layerscape architecture, the industry's first software-aware, core-agnostic networking architecture to offer unprecedented efficiency and scale. A member of the value-performance tier, the QorIQ LS1021A processor provides extensive integration and power efficiency for fanless, small form factor enterprise networking applications. Incorporating dual ARM Cortex -A7 cores running up to 1.0 GHz, the LS1021A processor is engineered to deliver CoreMark performance of over 5,000, as well as 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 QorIQ LS1021A processor features 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 processor is pin- and software-compatible with the QorIQ LS1020A and LS1022A processors.
