The highly-integrated Microchip WFI32E01PC is a Trust&GO secured platform-enabled Wi-Fi MCU module that has been pre-provisioned for cloud platforms. The module was developed to the Wi-Fi Alliance (WFA) specification and is fully certified with: Federal Communications Commission (FCC), Industry Canada (IC) and European Radio Equipment Directive (RED). Microchip’s Trust&GO platform inside the WFI32E01PC quickens the process of network authentication using secure element technology, which is preconfigured and pre-provisioned for cloud authentication.

The new technology uses a premium PIC32 MCU core, rich peripherals and a proven hardware security platform, allowing it to both provide Wi-Fi and also to serve as a powerful MCU core for the entire IIoT system.

“With increasing attacks, traditional software data encryption is no longer sufficient to protect transmitted data. Devices need a hardcoded, verifiable, trustable identity to securely connect to the cloud,” said Steve Caldwell, vice president of Microchip’s wireless solutions business unit. “This is the first secure, pre-provisioned MCU with Wi-Fi that is shipped factory direct or through distribution.”

Microchip has a wide range of products that can be used besides the module to simplify the development of IoT and IIoT systems. For example, the WFI32E01PC module can be paired with 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. with additional software drivers and hardware reference designs to reduce project risk and time-to-market.

Microchip’s WFI32E01PC module is supported by the PIC32MZW1 Curiosity Board. Software support includes Microchip’s MPLAB X 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 54-pin SMD 24.5 x 20.5 x 2.5 mm device is available in volume production in 10,000-unit quantities starting at $8.14. Also available are module options with external antenna.
