WFI32 Standalone Wi-Fi MCU Modules

Microchip’s WFI32 is an industrial IoT Wi-Fi module supporting 2.4 GHz 802.11 b/g/n

WFI32 from Microchip Technology is a standalone and fully certified Wi-Fi module supporting 2.4 GHz 802.11 b/g/n radio modes. Specially designed for industrial IoT applications, WFI32E01PE contains the PIC32MZW1 series Wi-Fi SoC, which is a 200 MHz high-performance MCU with industrial leading Wi-Fi connectivity and rich peripheral options. PIC32MZW1 has 1 MB embedded Flash and 256 KB SRAM, empowering embedded designers to rapidly build complex IoT software covering WLAN, TCP/IP stack, RTOS, and Cloud connectivity and application. Various types of peripherals, such as Ethernet, USB, ADC, CVD touch buttons, and CAN, make PIC32MZW1 a perfect system core to realize most application features.

As a total system solution provider, Microchip offers a broad portfolio that simplifies IoT and IIoT systems when pairing the WFI32E01 module with other Microchip market-leading components, such as KSZ8081 family of Ethernet PHYs, MCP2542WFD family of CAN transceivers, and other wireless technologies [Bluetooth Low Energy (BLE), Long Range (LoRa®) and IEEE® 802.15.4]. Both the WFI32E01PE and WFI32E01UE provide excellent WLAN functions covering the latest Wi-Fi security standard, Wi-Fi protected access 3 (WPA3), and all the general Wi-Fi functions like AP, STA, SoftAP with eight connected STAs, TLS, and more. The software development of the WFI32E01 module is supported in Microchip MPLAB and Microchip Harmony v3.
