LS1021A Time-Sensitive
Networking Reference Design
OVERVIEW
o The LS1021A Time-Sensitive Networking (TSN) Reference
Design platform allows developers to design with the
new IEEE Time-Sensitive Networking (TSN) standard. The
board includes the QorIQ Layerscape LS1021A industrial
applications processor and SJA1105T TSN switch. The
LS1021ATSN is supported by an industrial Linux SDK
with Xenomai real time Linux, which provides utilities for
configuring TSN on the SJA1105T.
With virtualization support, QorIQ Layerscape Secure
Platform Trust Architecture, Gigabit Ethernet, SATA interface,
and an Arduino Shield connector for multiple wireless
modules, the LS1021ATSN is ready to support industrial
IoT requirements.

READY-TO-MANUFACTURE DESIGN
The LS1021ATSN reference design can
significantly reduce investment costs for
OEM or ODM manufacturers seeking
to design new TSN-capable industrial
automation systems. The LS1021ATSN
is provided with the OpenIL industrial
Linux
®
distribution with support for
netconf configuration of the TSN features
and real-time performance with Xenomai.
NXP provides the complete design files
for the board, as well as detailed bill of
materials (BOM) at no additional charge.
