LS1021A/LS1020A Overview

The QorIQ LS1021A Tower System Module (TWR-LS1021A) is a low cost, high-performance

evaluation, development, and test platform supporting the LS1021A processor, which is based on the dual

ARM® Cortex™-A7 cores up to 1.0 GHz. TWR-LS1021A feature an integrated on-board probe for future

cost savings, along with third-party platforms developed by Freescale’s embedded board solution partners.

The TWR-LS1021A is optimized to support the high-bandwidth DDR3L memory and a full complement

of high-speed SerDes ports. The system is lead-free and RoHS-compliant.

The TWR-LS1021A additionally provides support for pin-compatible subset device, the LS1020A

processor. Throughout this document, references to LS1021A should be presumed to apply equally as well

to the LS1020A, unless otherwise noted. Similarly, references to TWR-LS1021A apply equally to the

TWR-LS1020A.
