QorIQ LS1 Processor Family
QorIQ LS1043A and LS1023A
Communication Processors
Quad-core, 64-bit ARM-based processors
designed for enterprise edge industrial
and networking applications
Overview
The QorIQ LS1043A processor is Freescale’s first quad-core, 64-bit ARM®-based processor for
embedded networking. The LS1023A (two core version) and the LS1043A (four core version)
deliver greater than 10 Gbps of performance in a flexible I/O package supporting fanless
designs. This SoC is purpose-built solution for small-form-factor networking and industrial
