Microchip Technology has released its first Wi-Fi microcontroller (MCU) module with the company’s Trust&GO-enabled verifiable identity. The integrated WFI32E01PC Trust&GO platform-enabled Wi-Fi MCU module streamlines the process of network authentication using secure element technology, which is preconfigured and pre-provisioned for cloud authentication, making it easier for developers who are designing secure industrial IoT (IIoT) systems. The module also can be used in home automation devices, computing, and consumer devices.

The new “all-in-one” module also addresses the challenge of system-level support when using various chips from different vendors. The integrated solution, featuring a premium PIC32 MCU core and advanced peripherals, provides industrial-grade MCU functionality, Wi-Fi connection, and hardware security and authentication, while improving radio frequency (RF) power and providing a higher level of security.
The WFI32E01 module can be paired with other Microchip components, such as the KSZ8081 family of Ethernet PHYs, MCP2542WFD family of CAN transceivers, sensors and radio technologies including Bluetooth Low Energy (BLE), Long Range (LoRa) and IEEE 802.15.4, for a total solution.
The WFI32E01PC is compliant to the Wi-Fi Alliance (WFA) specification and fully certified with the following world regulatory agencies: Federal Communications Commission (FCC), Industry Canada (IC), and European Radio Equipment Directive (RED).

The WFI32E01PC includes the PIC32MZW1 Curiosity Board, which is qualified with AWS IoT Core and is listed in the Amazon Web Services (AWS) Partner Device Catalog. It contains an out-of-box demo, featuring registration and communication with AWS IoT Core and interaction with the on-board sensors using Alexa Voice Service (AVS). The AWS IoT Core qualification includes code samples, WLAN software, and network stack, which can be found in MPLAB Harmony v3.
Microchip offers several options for software support, including the MPLAB X Integrated Development Environment (IDE) and MPLAB Harmony v3 embedded software development framework. Supporting tools include the on-board debugger and in-circuit serial programming header for MPLAB Snap, MPLAB PICkit 4 or MPLAB ICD 4 external programmer/debuggers.
The WFI32E01PC-I (54-pin SMD 24.5 x 20.5 x 2.5 mm) device is available in volume production in quantities of 10,000 units, starting at $8.14. Module options include with an external antenna and without the Trust&GO security feature. Products may be purchased at Microchip’s purchasing portal or through an authorized distributor.
