Product details
Overview
ZWIR4512AC1RI from Integrated Device Technology (IDT) is a secure, programmable wireless IPv6 module integrating an ARM® Cortex™-M3 MCU and IEEE 802.15.4-compliant RF transceiver. It delivers 6LoWPAN mesh networking, IPSec/IKEv2 end-to-end security, and operates in license-free 868/915 MHz bands with -110 dBm receiver sensitivity and up to 10 dBm TX output (US mode). It targets battery-powered sensor nodes in smart metering and industrial automation.
For engineers reviewing the ZWIR4512AC1RI datasheet, ZWIR4512AC1RI pinout, ZWIR4512AC1RI application, or ZWIR4512AC1RI equivalent, key selection considerations include its integrated 6LoWPAN stack, ETSI/FCC certification, 30-pin edge-board package, 19 GPIOs with ADC/DAC/PWM/USB/CAN/I²C support, and ultra-low 3.5 µA standby current.
Technical Context
The ZWIR4512AC1RI implements a full 6LoWPAN protocol stack with mesh routing on an STM32F103RC ARM® Cortex™-M3 core running at up to 64 MHz, paired with the IDT ZWIR4502 transceiver. It supports BPSK (20/40 kbps) and O-QPSK (100/250 kbps) modulation across EU (4 channels) and US (10 channels) frequency bands.
Security is implemented via hardware-accelerated, standards-compliant IPSec and IKEv2 protocols enabling authenticated, encrypted IPv6 communication over untrusted networks. Power management includes four low-power modes - Run, Sleep, Stop, and Standby - with 3.5 µA quiescent current and RTC retention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Silicon Labs EFR32MG21A020F768IM32 | Sub-GHz + 2.4 GHz dual-band SoC; higher TX power (20 dBm); no pre-integrated 6LoWPAN stack - requires SDK integration | Requires full software stack porting; better suited for custom protocol stacks or Bluetooth Mesh coexistence | Choose when multi-band flexibility or higher RF output is prioritized over out-of-box 6LoWPAN readiness |

FAQ
What is the primary function of the ZWIR4512AC1RI?
The ZWIR4512AC1RI is a fully integrated, pre-certified wireless IPv6 module combining an ARM® Cortex™-M3 microcontroller, IEEE 802.15.4 transceiver, and royalty-free 6LoWPAN stack with IPSec/IKEv2 security. It serves as a standalone, programmable endpoint for secure, low-power sensor networking - eliminating the need for external MCUs or RF design. Its architecture enables direct IPv6 addressing and mesh routing in battery-operated devices.
Does the ZWIR4512AC1RI support both EU and US frequency bands?
Yes, the ZWIR4512AC1RI supports license-free operation in both EU (865–868 MHz, 4 channels) and US (902–928 MHz, 10 channels) bands. It implements BPSK and O-QPSK modulation per IEEE 802.15.4, with region-specific output power limits: up to +5 dBm in EU mode and +10 dBm in US mode. ETSI EN 300 328 and FCC Part 15.247 certifications are factory-applied.
How many GPIOs does the ZWIR4512AC1RI provide, and what peripherals are supported?
The ZWIR4512AC1RI provides 19 GPIOs in its 30-pin edge-board package. These support UART1/2, SPI1, I²C, USB, CAN, three ADCs (12-bit), two DACs (12-bit), 11 PWM channels, multiple timers, and JTAG/SWD debugging. Several pins are 5V-tolerant, and peripheral functions can be remapped via register configuration - detailed in Tables 2.1–2.3 of the official datasheet.
What power-saving features does the ZWIR4512AC1RI offer for battery-powered use?
The ZWIR4512AC1RI offers four low-power modes: Run (10.5 mA RX), Sleep, Stop (26.5 µA with RTC), and Standby (3.5 µA with RTC). Its ARM® Cortex™-M3 core dynamically scales clock frequency (8–64 MHz), and peripherals can be individually disabled. Combined with optimized 6LoWPAN stack behavior, this enables multi-year operation on standard coin-cell batteries in intermittent-sensing applications.
Is the ZWIR4512AC1RI pin-compatible with other variants in the ZWIR45xx family?
No - the ZWIR4512AC1RI uses a 30-pin edge-board package, while the ZWIR4512AC2 variant uses a 32-pin land grid array (LGA) package with two additional GPIOs. Pin assignments, mechanical footprint, and soldering requirements differ significantly. Migration between AC1 and AC2 requires PCB redesign; they are not drop-in replacements despite shared firmware and functional compatibility.
