As the IoT expands beyond home automation and drives deeper into home control and grows in building and industrial automation, the need for highly integrated, reliable and secured Industrial IoT (IIoT) connectivity is greater than ever. Microchip Technology has announced a WiFi microcontroller (MCU) module with Microchip’s Trust&GO-enabled verifiable identity.

For developers designing secure IIoT systems, Microchip’s integrated WFI32E01PC is a Trust&GO secured platform-enabled WiFi MCU module that is pre-provisioned for cloud platforms. The WFI32E01PC is compliant to WiFi 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).

Microchip’s Trust&GO platform inside the WFI32E01PC streamlines the process of network authentication using secure element technology, which is preconfigured and pre-provisioned for cloud authentication.

Unlike existing devices, Microchip’s new technology includes a premium PIC32 MCU core, rich peripherals and a proven hardware security platform – enabling it not only to provide WiFi but 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 WiFi that is shipped factory direct or through distribution.”

Unlike module-based designs, discrete designs can be difficult due to the need to develop drivers and circuits for multiple chips, especially when the chips are from different vendors. Often it is difficult to receive system-level support from vendors as their expertise is only in products they produce. Embedded designers need a highly integrated module solution providing industrial-grade MCU functionality, robust WiFi connection and hardware security and authentication.

The WFI32E01PC provides these capabilities and more in an all-in-one module, improving Radio Frequency (RF) power and providing a higher level of security.

In addition to industrial applications, the WFI32E01PC is designed for home automation devices, computing and consumer devices.

As a total system solution provider, Microchip offers a broad portfolio that simplifies IoT and IIoT systems when pairing the WFI32E01PC module with other Microchip market-leading 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. Microchip’s system solution approach provides ready-to-use software drivers and hardware reference designs, significantly reducing project risk and time-to-market.   

Microchip’s WFI32E01PC is supported by the PIC32MZW1 Curiosity Board. Microchip offers several options for software and hardware support. Software support includes Microchip’s 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 24.5x20.5x2.5mm) device is available in volume production in 10,000-unit quantities starting at $8.14.
