Secure Low-Power
Wireless IPv6 Module
ZWIR4512
Datasheet
Brief Description
The ZWIR4512 enables secure low-power wireless
IPv6 communication for sensors and small devices.
IDT provides a user-programmable, royalty-free
6LoWPAN stack with mesh routing capability with
the ZWIR4512. 6LoWPAN is an Internet Engineer-
ing Task Force (IETF) standard for building wireless,
low-power IP-based sensor and device networks.
These networks can easily be integrated into exist-
ing 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
(ARM, Ltd. trademark) microcontroller and provides
a rich set of GPIO and peripheral interfaces. Up to
192kB of flash and 32kB of RAM are available for
applications. Different low power modes are pro-
vided to save energy in battery-operated devices.
The modules provide superior radio properties with-
out the need for complicated external RF design.

1 Module Characteristics
1.1. Absolute Maximum Ratings
The absolute maximum ratings are stress ratings only. The device might not function or be operable above the
operating conditions. Stresses exceeding the absolute maximum ratings might also damage the device. In
addition, extended exposure to stresses above the operating conditions might affect device reliability. IDT does
not recommend designing to the “Absolute Maximum Ratings.”

ZWIR4512 Datasheet
3 Application Circuits
ZWIR4512 modules are designed to require minimal external circuitry. The following sections illustrate how
modules must be connected in order to ensure proper power supply, reset behavior, programmability, and radio
performance. Instructions for the connection of GPIO pins are not given.
3.1. Power Supply
All internal components of the ZWIR4512 that require a stable power supply are internally decoupled with a
number of capacitors. Nevertheless, the module requires one external decoupling capacitor between VCC and
GND. This is the minimal external circuitry required for proper operation.
The module provides two different power supply pins: VCC and VSTDBY. VCC is the normal supply voltage that
must be applied in Run, Sleep, or Stop Mode. During Standby Mode, the module is powered by VSTDBY and VCC
can be switched off.
Figure 3.1 shows two possible power supply schemes. Scheme a) connects VSTDBY to the same voltage source
as VCC. This is the commonly used configuration. However, scheme b) allows switching off VCC in Standby
Mode. This can help reduce power dissipation in applications with ultra-low power requirements. During the
complete standby phase, VSTDBY is powered from a buffering capacitor.
