Key Features
- Integrated hardware TrustFlex security accelerator with ECC608 cryptographic engine for TLS 1.3, ECDH, and ECDSA without software overhead
- 802.11 b/g/n Wi-Fi with pre-certified FCC/CE/IC radio module, eliminating costly re-certification for end-product designs
- 200 MHz MIPS32 core with 2 MB Flash and 512 KB RAM plus 3.3 V supply operation from 2.97 V to 3.63 V for embedded IoT gateway tasks
Applications
The WFI32E01UE-I is designed for secure Wi-Fi connected products such as smart plugs, industrial wireless sensors, and home automation gateways that require hardware-root-of-trust security and regulatory pre-certification. Its 200 MHz processor and ample Flash allow on-device MQTT/TLS stacks, OTA firmware updates, and edge analytics without relying on a separate application processor.

Frequently Asked Questions
How does the hardware TrustFlex accelerator in WFI32E01UE-I improve security compared to software-only TLS implementations?
The integrated TrustFlex ECC608 hardware accelerator offloads elliptic-curve cryptography operations such as ECDH key exchange and ECDSA signature verification, completing TLS 1.3 handshakes roughly 10x faster than a software library running on the 200 MHz MIPS core alone. Hardware key storage prevents extraction of private keys even if firmware is compromised, providing a physical security boundary that software-only solutions cannot match.
What Wi-Fi standards and supply voltage does WFI32E01UE-I support for battery-assisted IoT nodes?
WFI32E01UE-I supports IEEE 802.11 b/g/n single-band (2.4 GHz) Wi-Fi with a nominal 3.3 V supply ranging from 2.97 V to 3.63 V. The 2.97 V minimum enables operation from a discharged LiPo cell through a low-dropout regulator or directly from a supercapacitor in energy-harvesting designs. Data rates reach up to 72 Mbps in 802.11n mode for high-throughput sensor burst transfers.
Does WFI32E01UE-I include pre-regulatory certification that reduces development time?
Yes. The module carries FCC, CE, and IC (Canada) pre-certification for the integrated 802.11 b/g/n radio. End products using the module in its certified configuration can leverage this modular approval, avoiding independent radio testing that typically adds 8 to 12 weeks and $5,000 to $15,000 in testing costs. This is a significant advantage for small-volume IoT product launches with a 12-week factory lead time.
How much local code and data storage does WFI32E01UE-I provide for edge computing tasks?
The module integrates 2 MB of on-chip Flash program memory and 512 KB of SRAM, running a 200 MHz MIPS32 processor. This is sufficient to host a full RTOS, a Wi-Fi network stack, TLS 1.3 libraries, MQTT client, and still retain 500 KB or more for application logic. Combined with the 54-pin LCC footprint, the device eliminates external memory chips in most IoT gateway reference designs.
