ZWIR4512 Secure Low-Power Wireless IPv6 Modules

The ZWIR4512 enables secure low-power wireless IPv6 communication for sensors and small devices. ZMDI provides a user-programmable, royalty-free 6LoWPAN stack with mesh routing capability with the ZWIR4512. 6LoWPAN is an Internet Engineering Task Force (IETF) standard to build wireless, low-power IP-based sensor and device networks. These networks can easily be integrated into existing IT infrastructure or operate autonomously.

Secure communication is provided by standard-compliant implementations of the Internet Protocol Security (IPSec) protocol suite and the Internet Key Exchange Protocol version 2 (IKEv2), which enable highly secure end-to-end communication, including over unsecure network nodes.

The module is powered by an ARM® Cortex™-M3 microcontroller and provides a rich set of GPIO and peripheral interfaces. Up to 192 kB of flash and 32 kB of RAM are available for the user application. Different low power modes are provided to save energy in battery-operated devices. The modules provide superior radio properties without the need for complicated external RF-design.
