Overview
Secure hot spot
The QorIQ TWR-LS1021A Tower system module is the most feature-rich and high-performance
Secure IoT gateways
Tower system offered by Freescale. It enables compatibility and interoperability with the
HMI enabled Programmable
growing list of Tower expansion modules, providing an easily accessible and interchangeable
Logic Controller
suite of capabilities and features to support rapid prototyping as well as software development
programs. The TWR-LS1021A module is engineered to enable a wide range of applications,
Secure network attached
from IoT gateways to industrial controllers, secure access points and asset management
storage (NAS)
systems. Customers benefit from the high level of integration, excellent balance of performance
Asset management and tracking
to power, and robust reliability.
HMI enabled controller
Setting the TWR-LS1021A module apart is its outstanding level of performance delivered by
Robotics
the QorIQ LS1021A processor incorporating dual ARM Cortex -A7 cores running up to 1
GHz and delivering more than 5,000 Coremarks of performance. The module offers higher
integration levels than any prior Tower main processor board, which enables true single
board designs to be supported. As a result, both design effort and complexity are reduced.
In addition, the TWR-LS1021A module offers HDMI, SATA3 and USB3 connectors and a
complete Linux software developers package.
The TWR-LS1021A module provides a comprehensive level of security that includes support
for secure boot, Trust Architecture and tamper detection, in both standby and active power
modes. Together, these features safeguard the device from the point of manufacture to
the point of deployment. This ensures the device is protected from malicious hacking and
guarantees end products can support highly secure nodes.
