IDT's ZWIR4532 is a programmable low-power secure IPv6 communication module for Internet of Things (IoT) device networks. Sensors and devices can operate autonomously or connect to local or global IPv6 networks using the ZWIR4532. The ZWIR4532 serves as a universal secure radio communication module for applications with low bandwidth requirements.

The module incorporates an ultra-low-power Arm® Cortex®-M0+ 32-bit microcontroller which is running the network stack. In addition, the user application can run on the microcontroller. This helps minimize the size, complexity and overall BOM. A rich set of digital and analog peripherals is available for interfacing with external application components. Approximately 128 kB of Flash and 4 kB of RAM are available for user applications.

IDT offers the SensorShare™ user programmable royalty-free 6LoWPAN network stack with mesh routing capability for the ZWIR4532. 6LoWPAN is an internet engineering task force (IETF) standard for wireless low-power IPv6-based sensor and device networks.

Secure communication is provided by a standard-compliant implementation of the Internet Protocol Security (IPSec) protocol suite.
